LEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE♬


Hellllllllllllllllllllloooooooooooo, I'm Christina and I did mine on TASTE !!!!!!(^-^)
Did you ever think of living in this world without senses?????????????????????...........I think we should be thankful for our five senses. Taste buds protect humans from harms. Of the human senses, the sense of taste is not nearly as important as sight, smell, and hearing. However, it does help protect us from eating spoiled or poisonous foods.

Taste:

The particular quality that different foods and drinks have that allows you to recognize them when you put them in your mouth. (from dictionary)

Taste buds and taste cells


Taste buds were given their name because they look like microscopic flower buds. Each bud is hidden just beneath the surface of a papilla. When microscopic molecules of food enter the pore of a taste bud, they come in contact with taste cell. Nerve fibers connect each taste cell with the brain. The sense of taste is not that simple. Taste cells are also connected to one another by nerve fiber. They exchange and combine taste information before it is sent on to the brain. Taste buds wear out and are replace with new buds every week or two.
Think of all the different tastes you enjoy. In ice cream there so many flavors. You might expect that there are hundreds or even thousands of different kinds of taste cells in the taste buds of your mouth. Actually, only five different taste cells are known, including one that was finally proved to exist on 1997ish.

taste detectors


The four basic taste are sweet, salty, sour, and bitter. the fifth is called UMAMI. A century ago a Japanese scientist gave the name UMAMI ti taste he could not identify in seaweed. Now the actual taste cell that detect umami in food have been identified. UMAMI is hard to describe, savory flavor. It is the taste of natural chemical called glutamate. Some scientists suspect that there may be a few other kinds of taste detectors in taste buds. A sweet taste usually signals a food high energy. A salty taste signal a food that can replace salt lost by sweating when a person exercises or does hard physical work. A sour taste often signals that fruit is not ripe. Each taste give important information about foods.



Taste and smell



Having cold is not fun. T^ TTTTTTTT often it starts with sore throat. Later, even though your throat feels better, you may have a runny nose. You may have trouble breathing through your nose. You may have trouble smelling and even tasting. Your sense of taste is linked to your sense of smell. Scent detector send message to your brain about food's smell as the same time as taste detector sending message to the brain about its taste. The flavor you taste is the result of both scent and taste. When you have a cold, the thick mucus in your nose prevents the scent detectors there from working very well. but you don't have to have a cold to see how important a food's smell is to its taste.Get some jelly bean or candy and chew them. one at a time, notice how you can identify their distinctive tastes. spread the candies and close your eyes. With one hand, close your nose tightly so you can't smell. With other hand, pick up candy and eat it.Can you recognize its taste? I couldn't. barly .................Sometimes, even the sound of a food as we eat it adds to our enjoyment.

Your Sense of taste:*

Our senses taste detect bitter-tasting and possibly dangerous substances before we swallow them. The
human senses of taste is much simpler than our enses sight, hearing, and smell. It is, in fact, tied in some ways to the sense of smell.
What we call the flavor of a food or drink is partly its scientists have studied the sense of taste in rats, catfish, mud puppies have helped us understand how people sense all of the flavors in their live.


*LOOK AT YOUR TONGUE

♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪♪

Your tongue, you'll notice, is not a smooth surface. It is covered with small bumps. The little bumps are called papillae. Papillae come in different shapes. Some look like odd-shaped mountains. Some are flat topped and some are mushroom shaped. Just below the surface of each papilla are taste buds. The papile shaped like mushrooms contain betweeb one and five taste buds. The other kind of papillae contain up to 250 taste buds, Although taste buds are cincenrated on the tongue, they can also befound on the roof of your mouth and the flap of flesh that dangles at the back of your mouth that are ready to help you taste all the flavor of the world.

FACTSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS

*I was curious why orange juice taste bitter right after you brush your teeth. The answer to that is that tooth pastes contain a detergent that keeps taste buds from senseing sweetness for a while.
*lemons have strong flavor, but they taste sweet after a persoon eats some African miracle fruit berries because after having them you no longer taste anything sour.
*Smoking harms a person's ability to detect flavors and scents. By keeping teeth and gums healthy, people also help keep their sense of taste healthy.
*Anything a women eats, drinks, or inhales can affect the well-belling of a baby developing................
*Enchiladas in red chili pepper sauce and other spicy food stimulate pain receptors in our mouth.

Scientific Method for my project:tongue_dia)00.jpg


Purpose: Find out how many taste buds a person have.

Hypothesis:The book i read said that many more women then men are supertasters.

Materials:

· Cotton swab
· Blue food coloring
· Reinforcement ring ( used in three hole binders)
· Magnifying glass

Procedure:

1. Dab blue food coloring on the tip of your tongue with the cotton swab.
2. Place the reinforcement ring on the tip of your tongue.
3. With magnifying glass, count how many pink bumps you see inside the ring. The tongue will take up the dye, but the papillae, tiny structures that house the taste buds, will stay pink.
4. Record the result.
Fewer than 15 pink dot means you are a "non-taster,” between 15 and 35 an average "taster" and over 35 papillae then you are a "super-taster.”


Observations: I tested on 20 people for my experiment 10 girls and 10 boys.

Conclusions: There was no supertaster ......but everyone had pretty much the same amount of taste buds. supertaster and nontaster. They suspect that nontasters may harm their health because of some of their food and drink choices. Foods like chocolates and broccoli, may be very sweet or bitter to a supertaster. Also, supertaster can detect slight differences in the amount of fat in milk. non taster cannot.
Scientists have tried to figure out why this is true. They believe it is more important for females to be supertasters because women are child bearers. so womens can avoid food or drink that might be harmful.

I had 19 taste buds in the reinforcement. (T ^ T) I guess I'm a non- taster ........................................................................

HOPE YOU ENJOYED READINNNNNGGGGGGGGGGGG KKKKKKKKK HAVE A AWESOME DAY




When we first started on this project, i wasn't sure which topic to do because i had so many things i was intrested on. The next day i thought about doing my science project on taste because that morning , my nose was pluged and i couldn't taste anything. I wasn't sure how we taste food and i was curious about how tongue works. I learned alot of facts through internet and books about taste. I didn't know senses were this important and how smell and taste is related. I learned many plants contain bitter-tasting substances that act as a defense against insects and other animals that might eat their leaves and stems and I learned the taste sense of animal.
There are a few things I would still like to know. In internet i read a information that said scientists who study the sense of taste now say the map shows that different flavors are detected in different regions of the tongue is wrong. They discovered that a single taste bud can be sensetive to more than one taste. Is that true?
Well, this was enjoyable and something new.

Smell

Introduction to smell:Importance:difference of the nostrils:connection of brain.
Smell can help you in many ways, it helps you when you are eating something or if your trying smell the nice fragrance of the early spring.
But did you know that the nostrils in our noses can acually smell the same things differently? First of all the right nostril finds odors more pleasantly,
so when your smelling through with your right nostril you will get to find the object more pleasant then the left nostril. The left nostril show a slightly better skill of identifying the object and naming the object. You might probably say why is it different.The reason why it is different is because the right nostril connects most directly to the right hemisphere and while the left links to the left side of the brain. Even for the left handers the dominant language centers are in the brain's left hemisphere. But the right hemisphere dominates for some of emotional processing.

*Wondering who does most of the smelling inside your nose? The part that does the most of our smelling is called the "olfactory epithelium"
this is a patch of yellowish tissue that is high up in the roof of our nose.In this yellowish patch, there are cells specially adapted for smelling, as well as supporting cells to hold the whole struture together.

My thought- Reflection- Evaluation & overall comment:

- Hi my name is Christina, and I am studying "smell". First of all to tell the truth I didn't think much about my subject because I didn't really get the point for doing this project but I started to get the hang of what I was doing and the expectations and I was like "wow I get an apportunity to learn on my own",so I began to think,"well I picked my own subject and nobody else chose it for me so why not give it a shot rather then letting go?". And I Tthought first I need a purpose for my project so I could carry on and I thought "what interested me the most that made me pick this subjec"t. And I tell you thinking about my purpose was kind of hard for me because I actually couldn't know what interested me about this subject. So after a while I read about this information that the right and left nostrils can smell the same things differently. So then I began to think about things more clearly. Because I didn't want an ordinary experiment that people uses everytime for smell. Because most of the time they make people smell fragranced objects with blindfolds on and I really thought I need something that nobody usually tries. So finally after worth of time digging information I came up with a satisfactory experiment. You can see in my conclusion on what happened and you can see the procedure to find out what kind of experiment it is.
_You might find it tiring to read through all this but I personally think it's worth reading for all the science lovers_*keep reading*and enjoy

-I actually quite enjoyed doing this project and also my subject. I think that I learned quite a bit of things through my subject because now I know that if you smell with our left nostril you can identify objects by name slightly better then the other one and when we smell with our right nostril we can actually smell less-pleasant odors more pleasantly than the left nostril.I was quite amazed to find out what really was going on when we smelled something, which we do every day even though we can't realize this skill of our "nostrils" because it's hardly noticable but it can be quite noticable if we try to know the difference.

-If I were to evaluate myself in this project. Well I wouldn't give myself a "good for you" mark I would probably give myself "would need a little more thinking". Because I truthfully think that I didn't give alot of thinking on this project then I wanted to.I think if there was a little bit more time then I think I could have used the time more truthfully and could improve my work. I think I would like to do something with what happens to the person when the persons left side brain is damaged what will happen?..And what will happen if the right side brain gets damaged.

Purpose:My purpose for this experiment is to find out if the left nostril and the right nostril can actually smell same things in a different way.

Hypothesis: My hypothesis is that even though it might be possible that smelling with our right nostril means more pleasant odor and smelling with our left nostril means that we can show a slightly better skills at identifying things. I don't think it really counts as everyone's nostril smell it that way. So I think not everybody's nostrils smell things this way.

Procedure:First, put a blindfold over a person and then make the person smell with their left nostril and smell the "hard to smell" objects, and then with their right nostril the person will also smell the same "hard to smell objects". Secondly, the person will smell with their right nostril and smell the "stinky "objects just like your gym strip that you didn't wash for a month. And then again the person will smell with their left nostril and smell this brutally "stinky" object. Thirdly, make sure you record this with making a chart or a graph indicating the differences of people with their nostrils.

Observations: I tested the teenagers the age 13~16, and the adults the age of 29~50, and the aged people the age of 60~80.
From what I saw the older people had some difficulties of identifying the differences of the both left and right of the nostrils. While the younger people and the adults showed a more clear sense of what they were smelling.

Conclusion: My conclusion, is that the more aged people had more trouble to identify the difference of the right and left nostrils,
but for the teenagers and most of the adults had no problem identifying the difference. 3:5 aged people could not take notice of the nostrils difference.
And 4:5 teenagers took notice of the nostrils difference. And 4:5 adults took notice of the nostrils differences.

My guess my failures and my rights:
I guessed through the first part of the thinking process. The part I was guessing is that first I thought maybe because the younger people is developing their smelling senses as they grow maybe the younger people have smelling senses less then the adults who are fully grown.

One of my biggest failure was when I thought I could conduct an experiment that included involvment of the brain and the nostrils it was almost impossible to include the brain in the experiment and the in the project because then the situation will become a little complicated. I had no experiment that was suitable to test the brain and the right and left nostrils. But I finally got an experiment that was suitable for me but I finally found out that if I was going to use the information as I was going then it wuold have been plagerism. It may be not a great failure to someone but it was sure to me!

One of my correct times was when for my hypothesis that not everyone's nostril's will give the same results. That hypothesis was one of my correct times.

Overall comment:
My comment on this whole thing is that this gave me a chance to actually learn by myself other then learning out of a book. And also gave me a chance to think and the chance to pick a topic that I was interested in so I was struggling that much because I chose it. And after a while I got a real hang out of it. And I suggest that you try this too! This can be for fun because it is fun and you will learn something that you dearly wanted to. If I got another chance I would like to do better than I did right now. It must have been hard to read this far but I hope you enjoyed it!
Thank you for reading one of the senses "Smell".

Optical Illusions

By Kimberley

Hi! I'm Kimberley, and I am studying sight and how optical illusions work for my project. When I first began, I didn't know what to study about. When we were told "You can study anything you want", I couldn't think of anything in particular because there are just so many interesting things! I finally decided on sight, but then I needed to narrow it down. I was first planning on filming a video of how to dissect a cow's eye because we'll be doing that later on, but then Mr. Truss suggested Optical Illusions. That just hit home because I've always been interested in them, and I have tons of books of them. I always wanted to know how an artist came up with them, and how they really worked, and now I have had my chance to find this out. This page is YOUR chance. In case you don't know, I have drawn some optical illusions, done testing and created an "Optical Illusions Journal". The journal contains many of my notes, observations and conclusions. When you think of optical illusions, what do you see? Swirling pictures that make no sense at all (or do they??)? Hidden meanings? Being fooled over and over again by a drawing ("...but that one looks farther/bigger/longer!") No matter what you think of, optical illusions are a way for artists to express a feeling or emotion, and for the public to enjoy and think and puzzle over their work. And, of course, they're ALWAYS plenty of fun!

Hope you enjoy reading about and looking at my project!



For my project, I have been drawing and testing some optical illusions. I began with doodles, one of which turned into the large drawing below. Then I experimented with drawing two circles and adding designs around and just inside them, to see if I could make one look larger than the other. I drew one to begin with, but whenever I drew one, I had a new idea of how to possibly improve it. I tried them all, and they can be found in my Optical Illusions Journal.

Look below, and what do you see? The grace and poise of a pirouetting dancer? A calm, gentle bird careening through the sky? A cautious, yet playful, rabbit? Anyways, please let me know what you think it looks like in the discussion titled "Illusion 1: Response". Thanks.
View my other illusions at my Optical Illusions Journal!

Bird-Dancer.jpg


Scientific Method for my project:
Purpose: Find out if I can create 3 optical illusions that have not been drawn before (at least not that I know of), and can be seen as at least two different 'pictures' (like the vase/two people picture) and at least 10% of people see it each way, make at least 90% of people confused about what it is, or make at least 90% of people think that it looks like something that it isn't.
Hypothesis: I believe that I can create at least 2 optical illusions that fit the above description.
Materials: Paper, pens, pencil crayons, markers
Procedure:
1. Research how optical illusions work and how we see.
2. Draw one optical illusion that you think will work.
3. Ask 30+ people what they see when they look at it.
4. Record the data and why you think that was the result.
5. Repeat steps 2-4 with 2 different drawings.
Observations: Look in my project journal!
Conclusions: See my journal!

Procedure has been adjusted to the following for my first drawing:
1. Steps 1 and 2 above.
2. Hand the 'subject' the picture on a diagonal, so that a corner is toward them, not a side, and they won't necessarily look at it one way first and not get a chance to see it as something else.
3. Ask 30+ people what they think the picture is of.
4. Record whether they thought it was a bird, dancer, or something else.
5. Analyze data and decide why you think the results turned out that way.

Procedure for second illusion:
1. Steps 1 of original procedure.
2. Draw an illusion that asks the famous "Which one is bigger?" question. (They have to be the same size in reality. Use background or covering designs to create the illusion of a difference in size.)
3. Make variations, to see which one the difference seems to be greatest in.
4. Poll people (if possible) to see which drawing they think seems to have the greatest effect.
5. Record data (if possible).
6. Analyze drawings to see why certain ones have more effect than others.

My findings, observations and general notes can be found in my journal.

Reflections and Evaluation

I have learned so much from doing this project on optical illusions. I now know that when you ask "Which one is bigger?", it is better to make the "distraction" design bigger and darker, so that the 'tester's' eyes will be drawn to it, but if you make it too big or too far away, then your 'tester' doesn't focus on it anymore. I also know that if I ever try to draw the Bird-Girl again, and want the results for the two most common answers (which led to the naming of this picture) to be more equal, I need to make it look slightly more like a girl and slightly less like a bird - enough that fewer people will say bird and more will say girl, but not so much that the scale tips the other way completely.

If I had more time, I could have tried the 'Circles' illusion with shapes other than circles with triangles (how about ovals with arrows, or something else?). I also would have liked to see how many people would automatically say that one circle was larger, and how many have seen a similar illusion before and know that they should say that both are the same size. It would also have been interesting to have one paper on which the circles really WEREN'T the same size, and how many people would say "Same size!" because they've seen the illusion before. Then I would actually be doing my experiment on how many people will go by instinct and how many will go on what they have (possibly) seen in the past, while everyone still thinks I'm trying to do an experiment on how many people think they are not the same size.

I think the variations on the 'Circles' illusion went really well. I was able to begin with one drawing, and then keep on improving it, and finding out what did and didn't work (which, if you recall, I stated as something I wanted to find out in my introduction paragraphs). I think I could have done a bit better on the Bird-Girl if I had enough time to keep on improving it over and over, so that more people would say girl, and less say bird. It seems that it is very easy to imagine something is a bird because we don't always see them as a definite shape, such as when they are high in the sky, whereas a person we have a very definite image of, because most people see other people every day.

I have really enjoyed working on this project because it has allowed me to work on a more open project, and learn about something that not everyone wants to learn about. I think, if I did this again, I would try to do more of my drawing at the beginning so that I have more time to test people.

Thank you for taking the time to read about optical illusions, and my study of them. I hope that you have sincerely enjoyed it, and maybe you'll try creating your own, too!

Have fun!
Kimberley

Hearing

lofi.forum.physorg.com
ear_diagram.gif
www.electoneonline.com
For this project I'll be testing grade 8 boys and girls on their hearing and hoping for a good and interesting results.I'll also hope to find out whether listening to music using ipods or mp3 really could damage a teenager ear.Another thing that I would like to learn about during this experiment is whether hearing with only one ear would be easier or harder to hear compared to hearing with both ears.

Did you know that:
The human ear can distinguish some …
1400 different pitches
Here is a video to test on your hearing!Can you hear the two?

http://www.youtube.com/watch?v=30m3HfO7yM8
Hearing, what comes up in mind about this word well majority of you might say we hear with our ears but thats not all. How do we hear?What else can the ear do?What might be causing modern day hearing damage?What types of hearing damage are there?Well I'll be answering all of those for you.First how do we hear?It doesn't just sends vibrations in the ear and hits right into our brain there is more to it. First the sound goes in from the pinna which is the outside flap and is known as the outer ear.Next the sound hits the ear canal and hits three tiny bones called: the hammer, anvil and stirrup which is part of the middle ear.Once these little bones are hit it turns into vibration and goes up into the cochlea(part of in the inner ear).Once in the cochlea there will be tiny tiny hair cells which are those you must not harm or else hearing loss occurs, the hair cells then send the message into the brain a briliant thing.Second, what else can a ear do instead of hearing, well nto only you hear with your ear it helps you balance as well.First it is obvious your brain is always changing postions in which you are moving but most of the balancing comes from the ear.What might be causing modern day hearing loss? Did you ever say to yourselfs "its just one rock band for once a year what can it do to your ears"Well it can do alot.Just going to a rock band for 30 minuites is Over 128 to 512 times as louder then the number of decible you need to hear from a days explosure not to mention that rock bands take up to two hours.Another modern hearing loss device are the mp3's ipods and other portable music devices.It isn't the mp3 or the ipod itsself that is causing most of the damage but the earphones are! Did you know that the smaller the headphone the more damage of hearing loss it causes.Last of all but not least, what types of hearing damages are there well mainly there are three types of hearing losses.First the conductive hearing loss where hearing loss occurs when sound is not conducted efficiently throughout the ear,second the sensorineural hearing loss when hearing loss occurs when there is damage to the inner ear (cochlea),last but not least the mix hearing loss where it is the mix of sensorineural hearing loss and the conductive hearing loss combined.
The scientific mothod for my projects experiment is:
Purpose:
For this experiment I would like to find out how well people can listen and find things without seeing where it is and finding out the differences between one ear / both ear,whether the distance of an angle would effect someones hearing and whether age difference would bring a difference.

Hypothesis:
Some of my hypothesis were that the distance of the angle would bring big impact amoung the results because the further the distance the sound waves that are coming out of the thing would fade each time i go farther. Having only one ear to listen to a sound would be alot harder because its almost like your're hafly death except only for a minute and i'm also guessing that age differnce would bring a difference in results becuase of the amount of sound each person has been through are different even if by a year.

Materials:
sound-proof room, ticking watch , pencil,paper, blindhold,5 metre sticks

Procedure:
1. Place four metre sticks evenly around a chair.
2. Get volunteers within different age groups.
3. blindhold a volenteer from the first group and see how far can they go on finding the watch by listening to its ticks at each different types of angle.
4. Then ask the volunteers to cover an ear and find the ticks at different angles.
5.Record each persons result and do steps 3-4 with every volunteer.
*due to time I wasn't able to get different age groups for this experiment.
_Observation_:
During this experiment i have obvserved that there are some strange gaps between good hearing and bad hearing during each test, I am also guessing that the enviroment one lives in makes a huge imapct amoung ones hearing.Another really intresting fact was that people could hear better with one ear instead of two.
graph.jpg
graph2.jpg
_Conclusion_:
I was right on how different anlges and distances made a nig impact for example people were able to hear better when the clock was beside the ear or in front of the face while hearing from the sides made it alot difficult for some others but not only your not half death also people were able to hear better with only one ear because all the sound would be concentrated on one ear instead of both so that the sound waves weren't so fade compared to using both ears.

_Reflextion_:
I have learned so much about one of our five senses,hearing, hope to learn more about the five senses in a near research on the human body,I really enjoyed this project and learned alot at the same time.What I could haev done for the experiment was to use different age groups and test out the results in which group would go the farthest majority. I also could have done farther research in how to prevent to much hearing damage and test whether it'll work or not but that will be for my next studies for science.
Hearing, alot of times students might think of well a concert to a rock once a month won't damage my hearing too bad, thats not true! Did you know that just going to a rock band is 128 to 512 decible loud and with that sound level it could damage your ear within just 30 minutes! Uaually rock band concerts last around 2 hours.There are three main types of hearing damages, one,Sensorineural when inner ear nerves become damaged and do not properly transmit their signals to the brain.Two, Conductive hearing loss when disorder happeans within the outer or middle ear and finally Mixed hearing damage which is when sensorineural and conductive hearing loss put together.
_Evaluate_:
What went well?My research was totally going smoothly in what I wanted and what I didn't also in mny other different areas
What could have been improved on?I could have had more time in doing the experiment and tested on other age groups.
What did you like about this process? I really liked how instead of sitting in a classroom doing paper work we are presentig a project we all love to learn and show it to the world as a class what could be done.
What would you improve?I would want ton improve on by asking more questions on the five sense and looking up the answers to hepl others who need the information, I also would like to share more information to others so that we are all learning.

Fear & Phobias

By: Delia, Denny and Shirley



woman_in_mirror_1_.jpg





Welcome to our Page of Phobias or Fear as you might call it. We don't think that there is a person on this planet that is not afraid of something. They are just too afraid to tell people because they might think it's too embarrassing. It's ok admit it and you'll be fine ;). Well we don't just get a phobia (born with it), we have to go through something that will frighten us to do it again, or scared that it might happen to you so it becomes a new phobia on your list. You can get that phobia even if it doesn't happen to you. It could happen to anybody and you just have to see it and there, like I said its a new phobia on your list. We have taken some experiments and recorded some answers. Please continue....it might just be helpful one day. :)

Experiments:

Objective: See if people get more scared by something they think they feel rather than something they know when they're feeling.

Hypothesis:(all of ours) The person we are experimenting on will have no idea what we are putting their hand into. That will frighten them, but once they actually feel what is in the bowl they would be more scared, but once we tell them what it is they will be fine with it.

Materials:
- bowl
- boiled spaghetti
- paper towel
- someone to test it on

Procedure:
- the person that we are doing the test on will have to answer us a survey
- then we will cover their eyes with our hands
- put hand in bowl telling them its something gross
- see their reaction
- answer a different survey after the experiment
- tell them what it really was

Part 2
During the experiment we had showed higher order thinking, and with higher order thinking we also had fun. There was only one person who actually believed it was worms he was touching in the bowl. The others seem to have outsmarted us. We had more people wanting to be our Ginny pigs than we expected.Getting them scared was the main part, so that is what we did. It seemed that people got more scared before putting their hand into the bowl than after. I hope they had fun, because we sure did .

Conclusion:
Our hypothesis was that they would get really scared when we told them what "was" in the bowl. The fact is, we were wrong. Most of their reactions were scared at the beginning and relieved at the end. One person had an idea of what it could be, there was one who believed it was worms, and one that knew what they were.

Since they got more scared before they have put their hand in the bowl, we have proven what we wanted to prove. We wanted to prove that people get more scared by just thinking that it's something gross in the bowl. When they actually felt what it was they thought this was a joke, well at least some of them. Maybe this will help you that at lest people get more scared before than when they are actually doing something.

Doing this experiment made us learn that you should be brave sometimes too. Sometimes it's not a big deal to put your hand in something especially when you are being experimented on. If you think that oh my god this is going to be really gross or scary... no way would we do that to you. Well maybe if you were in a real science lab and you were experimented on the you would have a reason to be scared. Apparently thats how most felt but right when they were going to put their hand in the bowl we felt that their heart rate was going up. then after they realized it was not such a bad thing.


There's also one more thing, we did the exact experiment to our homeroom teacher and when we blind folded her, she got REALLY scared. She wouldn't touch it no matter how many times we tell her its harmless. She even asked one of her students to touch it for her. But it's okay we still love you! Good times...>=D




Horror Movies in a Year:
Fear can be real or just imaginary. Simply touching pasta can make us think that we're touching worms, which we're not. We did a survey on how many horror movies people saw in a year and most of them picked 1-2 times a year. That tells us that not a lot of people like to see horror movies because it causes them nightmares.
I think the reason we have nightmares for few days after watching a horror movie is that we see & hear something scary
and we think about it so dreams naturally happens.

Causes of fear & phobia:
It is generally accepted that phobias arise from a combination of external events and internal predispositions, some phobias such as arachnophobia (fear of spiders) and ophidiophobia (fear snakes) however, many arise more easily due to an evolutionary trait that conditioned humans to fear certain creatures that could cause them harm. In a famous experiment, Martin Seligman used classical conditioning to establish phobias of snakes and flowers. The results of the experiment showed that it took far fewer shocks to create an adverse response to a picture of a snake than to a picture of a flower, leading to the conclusion that certain objects may have a genetic predisposition to being associated with fear. Many specific phobias can be traced back to a specific triggering event, usually a traumatic experience at early age, social phobias and acrophobia have more complex causes that are not entirely known at this time. It is is believed that heredity, genetics and brain chemistry combined with life experiences to play a major role in the development of anxiety disorders and phobias.


Cure the Phobia:
There is a way you can cure your phobia. It might not work that great the first time but once we do it twice or three time it will probably cure you. Now we did not try to cure anybody because we imagined that it would be hard. If you go down you can watch a video of someone curing somehow also from a needle phobia.



Reflections:

We have learned a few things from doing this project. People usually get more scared when they are younger. Since they don't get used to the fact that the boggy man is coming from when they are small they surely wont get scared after a few years. For some of us the feeling is not as gross as we thought it would be. If we had time enough we would have time to cure someone if we could, well if it wouldn't work at least we tried (we didn't try it, just saying). This project was fun a few arguments but not as many as we thought it would bring us. Here's a few questions we have been asked hope they're useful. :D
S:I think this science project gave me more knowledge about fear & phobias. It made me realize all of the wild and surprising things people are afraid of. Personally, my biggest fear is worm. Whenever I see one, it would disgust me and I would feel all uncomfortable, buts thats just me. There are worse reactions than mine, like if someone's scared of clown they'd run, scream and try to hide. Fear is created in our mind and our imagination could go wild even thinking about it. I really liked working on this project with my group and hope to do more of these projects in the future.

What we still want to know is how fear is created in us...How is it so popular?


Q: Why do people have fears?
A:Fear is created in our minds, and only you have the control to it, either stop it, or let it control your life. We don't really know the exact reason to why we have phobias, it's created in the inner mind.

Q: Why are some more scared than others?
A: Some people have a more afraid mind than others. Most likely, girls are the ones who are more scared. Most girls are sensitive and they think a lot about what is to happen or have a lot of "what if.." questions. As on the other hand, boys, like to think of themselves as strong human beings, but it could also be a natural thing, not to be scared of anything.

Q: What is the main cause of fear?
A: From what we have researched, our answer would be that something similar that have happened in the past. Now is haunting you. It also has something to do with your brain functioning.

Q: Why do people let fear control them?
A: People don't really have any power over the fear they get. People could also be "just that brave" and face it, or others might just only take it as a joke, or like in scary movies, NOT real. They could control your life.

Q: Why is fear such a weakness?
A: It's not usually a weakness, it can give you more power to run or get away from the thing you are afraid of. It could also give you a bad state to be in.
