Age and Reaction Time

Have you ever wondered why kids are usually better goalies than adults in soccer. I decided to answer that question.

As we age our reaction time decreases,

t

he brain processes nerve impulses more slowly, in addition at old age, one gets slower at performance of acts. There are also some things that can affect reaction time: Gender, physical fitness, fatigue distraction, alcohol, personality type, and whether the stimulus is auditory or visual. Younger people of 14 to 24 years have a shorter reaction time than people 25+ because they have a higher level of adrenaline and better reflex. After research we had to set up or hypothesis: If… We ask young and adult people to do our experiment, and see who have the faster reaction time.Then… The adult will have a slower reaction timeBecause… As we age the brain process nerve impulses get slower, and performance of acts, also the adrenaline and reflex levels are higher under 25 years old.

The experiment does support the hypothesis. In the hypothesis we noted that the reaction time will be greater in teens, in the experiment we had proved it. The media on teens reaction time is greater by 84ms. We have tested each one 20 timesSteps:1. Set up the reaction time test in the phone (humanbreakmark.com)2. Record the reaction times of 5 trials (per person)3. Compare data between teens and adultsRepeat the same process with 20 teens and 20 adults

Color’s effect on taste

Color’s effect on taste if far more vast than people think. If you have seen the Pizza Hut commercial and wondered why are they in a red room on a red couch with red pillows? The reason is red activates the hunger sense and gets you hungry. Different colors appeal to different people so companies try to use colors that would appeal to the people that like the product

There are many different flavors and types of gum that affect your brain differently

Gum Could Be The Secret To A 4.0

This

experiment was conducted to learn how gum affects brain activity and recall skills. I became interested in this topic because some kids chew gum in school, believing it is actually helping their performance. So I asked the question: What effect does chewing gum have on your `recall skills? I believe that test subjects will do better on a memory test while chewing gum because chewing increases blood flow to the brain, increasing brain activity, followed by increased recall skills. I gave the subjects two different memory tests. They attempted the first one while chewing gum. The second test they did chew gum. Then I compared the results. I found, in the amount of time that the subjects were given, chewing gum had little to no effect on their recall skills. For the majority of the students, the gum had no effect and they scored the same score with and without chewing gum. In this experiment my hypothesis was not supported because the subjects’ scores did not significantly improve when they took the test while chewing gum.

Color Vibrancy and Memory

Can vibrant colors help you remember words better?

If you take someone and give them a list of words, some printed in

bright fluorescent ink

and some printed in dull ink, which of the words would they remember easier?

In truth, the vibrancy of the ink doesn't have much affect on how easily they’re remembered. As shown in the graph, the results of performing this experiment were mixed. Some people remembered a lot more of the words printed in fluorescent ink, and others remembered more words printed in dull and near colorless ink.

What had more of an affect on which words were remembered was they way the words were organized. Words near the top of the list

had a tendency

to be remembered a lot more than words at the bottom of the list, so if you want to remember a list of words for a spelling test, organize the words from the ones you struggle

with the

most to the ones easiest to remember.

Color and taste

Bryana Taylor

Does the color of a drink affect someone’s ability to identify its flavor? To test my question I made an experiment. I colored white cherry Gatorade with food dye. The colors consisted of green, yellow, red, and blue. I put a couple of drops in each cup of each color and added the Gatorade. I then asked some subjects what they thought the flavor was, they were all fooled. In

the end of my experiment proved that color can affect the taste of food or drinks. Some changes in my experiment could be the number of subjects, the color of drinks. Have you ever wondered if color affected the taste of a drink? Slide7

Have you ever wondered what type of chocolate melts the fastest?

My group and I came up with what type of chocolate melts the fastest! We came up with dark chocolate because it had more

surgar and the other chocolates we used were bakers chocolate. Also the chocolates we used were white, dark, semi and 60 percent. The 60 percent chocolate took the longest to melt because it had less sugar then the other ones

Could

color

effect memory

Alondra Sotomayor

This experiment was conducted to test the question Do brighter colors effect the memory? Whenever you need to take a test you have to study and when you study you have to memorize the things for the test. Sometimes people have a hard time memorizing things so they hire a tutor of someone to help them with their work. Humans are unable to remember colors very well beyond the basic primary colors. For the color memory it depends on a person’s experience. Every person could have different results. After researching, I was able to form a testable hypothesis. I thought that if we attempt to memorize a list of words (some are dull and some are bright), then most people will remember the words of dull words. This is because most people are unable to remember more than just the basic primary colors. In the first seven trials more people remembered dull colors then bright colors. In the seven last trials more people remembered bright colors then dull colors. In conclusion, whenever you are taking a test it doesn’t matter if the words are bright or dull. This might be because of the fact that memory of color depends mostly on the persons experience in life. Slide9

Have you ever wondered how food processors make food so colorful?

My group and I came up with a test to find out how sight effects scent. We took the same flavor of

jello

and made it different colors. We had subjects smell the jello and identify them. We found that most subjects associate what they’re smelling, with the colors they’re seeing. The science behind it is that our eyes detect most of the things that our brain identifies, therefor sight influences our scent.

Melting Chocolate

By Bel Chisholm

In the end of my experiment after melting 60%

Chocolate, Semi-Sweet, and 100% Chocolate and White chocolate, White Chocolate melted the fastest mainly because of all of the added sugars. None of these results were really unexpected. I thought that all of these results would result like this based on how much sugar was in each chocolate bar. If I ever do this experiment again I would do more trials and have more chocolate flavors.

Color and TasteMellodi Henderson

For my 8

th

grade experiment I colored sprite with food coloring and had people drink it and we were trying to figure out if the color of the drink affected the taste of the drink. In

the end my experiment lead to these results. The reason we got the results we did was because the majority of people knew that it was sprite, so they knew what our experiment was and they figured out that it was sprite colored with food dye. There were a few unexpected results. A few people matched the flavor they guessed to the color of the drink. To get a more accurate result we could have tested more people. Maybe if we tried a different drink then people might have not known that we did sprite.Slide12

Color and taste

by Aubrey Lewis

For my 8

th grade pace experiment I did an experiment that tested how color of foods affect the way it tastes. We colored sprite red, blue, yellow and green and had people taste it to see if they were tricked by the color of the soda. We hypothesized that they would be tricked by the color, but our results proved us wrong and our test subjects were not tricked. Only a few of the people we tested thought that the soda was a flavor matching the color of the dye we added. Most of the people thought it was either sprite of 7up. Based of past experiments we studied we probably should have gotten different results. I think that the reason we did get these results was that when we dyed the soda we added to much color making the soda look too vibrant. To make our results more accurate I would dye the soda a color of an actual soda like orange or purple I feel like this would help us to get more accurate results. The above graph shows the guesses of what soda our test subjects thought that they were drinking. Slide13

Music and Reflexes

By: Taylor B

Have you ever listened to music while driving or doing other things? Well listening to music can be a hazard sometimes. My experiment was conducted to test if listening to music affected someone’s reflexes. To investigate my question, I gathered forty different subjects and had them catch a reaction time stick with and without music. An interesting thing that happened, is most of my subjects did better with music than they did while not listening to music. In the end, I learned that my hypothesis was inconclusive. The results showed that half my subjects did worse without music, half did better with music, and a few did the same.This graph shows how fast or slow the reaction times of many different subjects.Slide14

Friction

How does friction effect the movement of an object?

Avery Filbert

For my experiment I set up a ramp that would give a consistent speed. Then I rolled a toy car down the ramp. I used a smooth surface, a less smooth surface, carpet, and a smooth surface with water on it. After that I recorded the lengths of each try, from the base of the ramp to the car. And then recorded this experiment multiple times.

All in all the smoothest surface made the car go furthest. The smoothest surface went furthest because there was the least kinetic friction. The next best result was on the counter, the counter was smooth but not as smooth as the floor, the car went significantly more straight on this surface. The carpet was rough, I was surprised that the car went as far as it did, the care went very strait. The counter with water was the worst, the car was out of control and did not go far at all. The counter with water the car slid on and went all over the place.In conclusion, friction did not help the car go faster, and water did not help. Friction is the force that stops things from sliding across each other, the car had small wheels made out of hard plastic, the wheels slid smoothly across the floor, the smoother the surface, the faster and further it went.

Flying Objects

By Payton Lyons

Does projectile shape affect flying distance

?

For my experiment I got everyone into position, (Austin at the beginning of the hall, Emanuel in

the middle of the hall and me at the end). And we had Austin launch the projectile out of the slingshot keeping his drawback the same every time. Then we measured how many tiles the projectile flew, (one tile= one foot). After that we repeated the process 5 times for each projectile (pencil eraser, pen cap, pencil cap, student id and squishy). Lastly we recorded data, found averages, etc

.

While

looking at my data I noticed that 60% of the projectiles didn’t fly past 60 ft. I also noticed that the eraser flew the farthest by about 13 feet. The student id flew the least farthest averaging only 26 feet. Pen and pencil cap flew about the same distance, except for the pen cap flew a little bit farther.

In conclusion

t

he

pencil eraser flew the farthest because its pointed tip and sloped edges created a balance of lift and drag. This shows that projectiles with a pointed tip will be the best because of the way it forces the air around it. This experiment could help people who build missiles or aircrafts to help build a projectile that will reach its destination faster and uses less fuel.

Flying Objects

Does projectile shape affect flying distance?

By: Austin Brewer

For my experiment we started by getting into are positions. (Austin at the beginning of the hall, Emanuel in the middle of the hall, Payton at the end of the hall). Than we had Austin shoot 5 projectiles (pen cap, squishy, pencil cap, student id and pencil eraser) out of a slingshot. Then we would count how many feet in flew. W

ith the projectiles we figured out that (one tile= one foot). The feet and the averages are in the graphs to the right. As you can tell the squishy flew the farthest by about 10 feet. The student id flew the least.Slide17

Color

Vs.

Taste

Does The Color of a food or drink affect the way it taste?

In my experiment I randomly selected subjects and had them drink four different colors of the same drink, and then they would record what they thought the drink was for all four colors. By doing this many times we found out that groups guessed The drinks actual flavor correctly more often, and that purple was the hardest to identify. The reason subjects guessed incorrectly is because there eyes saw the color and matched a flavor in the past with the color of the dyed drink.

Colorful Brains!

Derek Pinder

In my experiment, we tested if Color effected memory. We saw if people could memorize more numbers in color than with just black ink. We found that people who tested in color did improve their scores. Every test subject improved their scores by 1-4 points. My hypothesis was proved correct. The science behind this is that the section of the brain that controls memory, The Central Frontal Cortex, is closely related to the section of the brain that recognizes and sorts colors, the Color Center.Slide19

Fast and easy

way to improve your test scores

We had ten students perform three mad minuets, each a different color. Each mad minuet had 80 problems and to make it far we had them do one test per day over a series of 3 days

After the experiments were concluded we averaged the results, finding that green had the highest average. White surprisingly came in second and blue came in last. we believe that this happened because like, colour affects, by Angelia wright stated, “When the world about us contains plenty of green, this indicates the presence of water, and little danger of famine, so we are reassured by green, on a primitive level” (Wright). Meaning we are more calm while taking tests on green paper. By: Peyton SimmonsSlide20

Age and Reaction Time

Does age affect reaction time?

This experiment was conducted to find who has faster reaction time,

teens or adults

? The data showed teens had a lower average reaction time then adults. We got these results because while you age your brain has more cross talk between both hemispheres (left and right), slowing reaction time. Another reason why the adults had a slower reaction time then the teens is because the corpus callosam

(Bridge between both hemispheres of the brain) breaks down which slows reaction time. A way to make reaction time faster is if the subject is in a situation that can affect health or survival. Another way to increase reaction time is to give the subject a goal to reach or have them exercise.By: Connor SmithSlide21

Shining a Light on Math

By: Magnolia Hazel

Does the Type of Light Have an Effect on Math Test scores?

This experiment was conducted to see what type of light can improve test scores the most. I thought that if we had subjects take three different math Mad Minutes in a different setting of light each then natural lighting would prove to be the best type of light because it stimulates Melanopsin in the brain which is linked to brain cognition. To investigate my question, I gave twenty subjects, in groups of four, a Mad Minute in each of the light settings and compared the data. 58% of the subjects did best in florescent lighting compared to the other types. The results were interesting because I thought natural lighting would be best because of the stimulation it provides to your brain. However, in the florescent lighting, it was easier to focus and you didn’t have distractions from the outside. In the end, I learned my hypothesis was wrong, Florescent is the best light setting for a test.

What color do you notice the most?

Have you ever been to the store with the intent to get a few things and got distracted by cool colors or things just caught your attention. This is how I got my question, What color do you notice the most? I put 60 test subjects through a test I would flash them a row of colors and then show them an answer key with same colors that were on the row but we also had 10 different colors that weren’t on it. From my information I concluded that people thought they noticed one color that wasn’t on the row. They also noticed neon colos.Slide23

Have you ever wanted to melt chocolate & make chocolate dipped fruit?

Kate Plaisted

Adding a little bit of chocolate to your fruit can turn it into a great snack or dessert.

 My group and I conducted an experiment to see what type of chocolate, out of milk, dark, and white, melts the fastest. We timed how fast each of them melted on a hot pot for three trials. After getting all the results we saw that dark chocolate melts the fastest. This makes sense because it contains much more cocoa than the others which also makes it healthier. We found that it melted twice as fast as white! Milk chocolate was close behind dark but does not have the same health benefits.

Dark chocolate is the easiest chocolate to make dipped fruit because it melts easily and becomes smooth while white chocolate is thicker and takes longer to melt.Slide24

Getting The Most Pop For Your Money

Emma Jones

Does the temperature of where you store your popcorn affect how many kernels you are left with after being microwaved?

You reach down into a giant bowl filled to the brim with delicious popcorn. Your fingers gather a handful of the buttery delight, but as you bring the popcorn to your mouth, the pleasure ends. Instead of the fluffy popcorn that you desired, is a hard, tasteless kernel. Because of this frustrating experience that seems to occur every time I microwave a bag of popcorn, I came up with a question to solve this issue: does the temperature of where you store your popcorn affect how many kernels you are left with after being microwaved? In our experiment, we placed ten bags of buttered popcorn in a fridge, ten in an ordinary room, and ten under a heat lamp. After some time, we removed the bags from their locations and microwaved them. After each delicious bag of popcorn went through the microwave, we counted each kernel in the bags that did not pop, and recorded our data. Our data showed us that the popcorn bags that were placed in an ordinary room had the least number of unpopped kernels.

One reason is happened was because ofthe moisture within the popcorn kernel. As said in a Popcorn Wikipedia article, “Popcorn is able to pop because the kernels have a hard, moisture, sealed hull. The pressure within builds, and a small explosion is the end result.” In order to get a fluffy piece of popcorn, the moisture the kernel needs to be unaffected. When we put bags of popcorn in a fridge and under a heat lamp, the moisture was affected, either drying out, or slightly turning to steam. This is why room temperature had the least number of unpopped kernels. So next time your popping a bag of microwavable popcorn, keep in mind that the buttery delicious popcorn your are striving for, is only obtained by storing your popcorn in an ordinary room. Slide25

It’s movie night with the family. You get out the blankets, turn on the new

Star Wars

movie, and cuddle up with a big bowl of buttery popcorn. Its half way through the movie, and your out of popcorn! All you see is a bunch of kernels at the bottom of your popcorn bowl, and you think to yourself what a rip off! This ongoing

led

me to my science question: Does the temperature of a popcorn bag before placed in the microwave affect how many kernels are left not popped. For my experiment I put bags of popcorn in the fridge, under a heat lamp, or just laying out on the table and popped them all then counted how many kernels were left in each bag. In the end my experiment proved that you should keep your popcorn in a room temperature area, in order for it to pop more kernels! Emme Dibble
