In 8th grade I won 1st at my school, 1st at regionals, and 1st at states using this project! I found the elevation of each baseball stadium in the US (all 30) and did some research on the air at different elevations. I found that the air is thinner when the elevation is greater and that means there's less air resistance. I found the total number of homeruns hit at each stadium in the 2002, 2003, 2003, 2005, and 2006 seasons to see if there was a correlation between number of homeruns hit and the elevation of hte stadium. I found that the Colorado Rockies stadium had both the highest altitude and the greatest number of homeruns hit! For my project I received 100% and my second 1st place at states!

In 6th grade, I did a project with laundry detergents. It was called,

Does the cost of Detergents effect the cleaning ability?

I came to an astonishing conclusion, just make sure to use stuff that stains really well before you wash them in your different detergents! Best of Luck! (This is a great desperation project, it can be completed in an afternoon. That is what I did and I still went to Regional Sci. Fair.)

THE ROCKET CAN
By Anthony Santa Maria
Problem: Which will make the rocket fly higher? Vinegar or Baking Soda?

Materials:
Meter stick
Empty balloon
Soda can
Chopsticks
Thin cardboard
Baking soda/Vinegar

Top of a plastic soda bottle
Procedure: You will need the can for your base. First, cut the cardboard out into a pair of wings. Then, glue the chopsticks to the “wings” for support. Leave some of the chopstick sticking out on the end of the wing. Next, poke holes on both sides of the soda can, and stick the chopsticks in the holes. Glue the wings on. Now, cut of the bottom of the soda can, and place the empty balloon inside. Now, pull the nose of the balloon out the top hole of the can. Next, glue the top of the soda bottle on the cut out side of the can. To launch your rocket, you first need to pour in the desired amount of baking soda into the balloon. Then, quickly pour in the vinegar and close the nozzle of the balloon. Shake up your rocket and let it fly. Next, do the same with the vinegar. Record your observations.

I did a project on oil pollution in the water. We all know that lots of oil gets spilled into the water each year but no effective method for cleaning it up has surfaced. So I took put water in a few containers and poured motor oil into them-try to used the heaviest grade. Then I chose three ways to try to remove the oil from the water, I used a spoon (scooping), cheesecloth (straining), and sand to see if I could make the oil sink to the bottom, combine with the sand and make to easy to scoop or vacuum out. You can use any methods you want though. The great thing about this project is that it applies to real life and will therefore be easy to find connections of how to use this. I did this in 5th grade and got an A!

One year my friend and I did a homemade thermometer. We took a plain water bottle, modeling clay, rubbing alchohal, water, a straw and tape. First we poured the bottle a quarter full with water, and half full with the alchohal. Then put the straw in so a little bit is sticking out of the top. Use the modeling clay and tape to keep the straw with a little bit in poking out of the top. when you place the finished project near a heater, the water will come up the straw. It eventually overflowed, which I think cost us first place.
WARNING: DO NOT PUT BOTTLE NEAR HEATER WITHOUT RUBBER GLOVES ON. RUBBING ALCHOHAL HURTS A LOT WHEN OVERFLOWING ON YOUR HANDS :)

for my science fair project i was wondering which type of liquid ( vineger, coke, orange juice, and water,) would rust a nail the fastest?
so i used four glasses one filled with vineger one with orange juice one with coke and one with water and put one nail in each glass and waited to weeks without touching it and then foind out which liquid would make it rust the fastest...and my controll variable was the water!!

I did a science project on music effect on little kids. I studied their movements, while asleep, as music was played. I got 1st place in my school, and 2nd place on Behavioral Science district wide.

Even though I didn´t make it to City Wide Science Fair, it was a great success to my community. Now daycares schools and parents know with what type of music their children will rest more and have a better sleep.

Meredith from: KY

I did this project in the fourth grade and I got 1st place out of my entire school (K-8), then I got sent to state where I was awarded $100.00. My project was:

"Whose mouth is cleaner, a dog's mouth or a human's mouth?"

I started off with 4 petri dishes filled with gelatin. Then took a swab of my mouth, my partners mouth, my dog's mouth and my partner's dog's mouth. I put these all in seperate petri dishes. I then observed the growth of different molds and fungus on the swabs. I let them sit for about 3 weeks. The end of the experiment was rather interesting.

Lish from IL suggests:

Last year for 7th grade, i did this really cool experiment on soda! (a great subject) My idea was to see which soda contained the most fizz out of Cherry Pepsi, regular Pepsi, Mountain Due, and Coca Cola. To make your hypothesis just know that carbonated water is what fizz is and the soda with the most sugar in it will have less room for carbonated water. The one with the most sugar will have the least amount of fizz. I made this little machine out of a few household items and some wood and i got 1st place in our class! This is a great project because after demonstrating at the science fair, you can hand out the free soda and that will make everyone want to come and see your project! (Trust me, it works!) It would also be a good 8th grade experiment or even 9th grade!

Marz K. from CALIFORNIA suggests:

In 7th Grade, I got to county (1st), then state(1st) with this project ! The project need these things:

-11 petri dishes

-5 name brand lotions- Lubrieum, Origin etc.

-5 ingredents of Lotions (100% cocoa butter, 100% baby oil, 100% aloa vera, 100 % nitro glisteren (handle carefully), and petroulim jelly (constant)

-3 packets of clear geltian

-bent butter knife (op)

-triple beam balence

-large cookie sheet

Make the geltian according to box, then disperse evenly into petri dishes. put all the petri dishes with geltian in them on a lare cookie sheet and put then in fridge. let them set overnight. them apply the same amount of each product/ ingredenent on to 10 of the perti dishes, label the perti dishes so you won't get mixed up. Leave one plain as this will be your control. put all perti dishes on the cookie sheet again and leave in a place they will not get distrbured and is room temp. then weight each dish every day recording your results. keep weighting until the control disappears. then record your data. then make your board look good! USE STICKERS THAT IS MY ADVICE TO YOU AND HAVE A BLUE AND LIGHT BLUE COLOR SCHEME AND HAVE THE TITLE HAVE SOMETHING TO DO WITH MOISTURE.

Morgan from Kentucky, USA suggests

In the 8th grade I did a science fair project involving the effectiveness of various hygiene products on the inhibition of bacteria. I left meat on my counter for several hours and rubbed it on the agar of 10 petri dishes. Then I soaked 60 hole punch circles in hygiene products---10 in mouthwash, 10 in antibacterial hand soap, 10 in Lysol, etc. Next I placed one of each type of circle at equal intervals around each petri dish. I allowed bacteria to grow for 48 hours under a bed and checked for bacterial growth. My hospital administrator allowed me to visit the hospital lab, and the tehcnicians offered to make slides of the bacteria and performed Gram Stains, which really made the bacteria visible under the microscopes. We were able to identify the type of bacteria and I measured the absence of growth around each soaked circle and recorded the zone of inhibition(where the bacteria could not grow) and plotted the results. It was a very interesting experiment that seemed to refute a lot of claims of products that supposedly kill so much bacteria. I learned so much and I really gained an interest in the field of microbiology!

Hilary King from Indiana suggests:

I did a project on whether snow was warmer on top or underneath. First, I filled a plastic container with snow. Next, I took two film canisters and filled them with warm gelitin. Then, I Put one canister under the snow and one on top. After that I took two small ragular themometers and put one on top and one under the snow. After a while take the canisters and open them. The top one should have a little ice in it. The other one should not. Take the thermometers, to see which temperature is higher. Record your data and state your conclusion and you should be set.

Megan from Georgia suggests:

My idea was to test the water found in our local areas to see if it has any threatening chemicals inside of it. Just buy a testing kit from epa.com/watersafe(Trust me it's cheap only $6), then gather up water from anywhere and test it with standard epa approved water. Trust it is a good project idea!

Julie from Oklahoma suggests:

My project was called Hay Infusion. You took 4 glass jars and 2 lids. Put hay and water in each of the jars. Seal 2 of the jars. Put one aerobic and one anaerobic in the dark and the other two in the light. Let it set for a while and see how much bacteria grows in each jar and take samples and transfer into tubes. Use a colormeter to test how dense the water is. Put observations in research. If possible, use a high magnification and take pictures with a microscopic camera. Use a high contrast board. It stands out.(felt, construction paper and computer printouts)

THIS PROJECT GOT FIRST PLACE OVERALL

Dominick from New York suggests:

My Idea was to measure the amount of fungus on my feet. For three days I wore three different kinds of shoes. Then I took the fungus off my feet with a Q-Tip. I put the fungus in a paper bag and wetit with water. Then I let it grow for five days. At the end of the five days there was a lot of fungus there.

Jo Anna Ogunmuyiwa from US suggests:

My idea is "Why is it important for you to throw out mold the minute you see it? Mold is dark spongy patches that sometimes appear on bread. when that happens you should throw it away imediatly. My project was to put one slice of bread in two sandwhicn bags. I put a little warm water in each of them. I put one in a warm place (above the stove) and one in a cold place(the fride). When I took them out 6 days later, the sandwich in the cool spot looked fine while the sandwich in the warm spot had dark patches of mold. You should throw away any moldy bread instaed of just picking it out because mold's spores reproduce in a few hours. That is what learned out of my science project.

Kevin from U.S. suggests:

I got 2nd place in school and 2nd place in city with this project!!! Does temperature effect the way a musical instrument sound? You need a tuner (machine used for finding out what note your instument is playing),a flute, and a violin(you can use any other instrument and can use other instruments if you dont have those), and a thermometer fortelling the temperature. Play your instruments in room temperature seeing & recording the temperature, date & the tune theyre in(make sure you remember the note you played). At night when its cold out put the thermometer & instruments outside all nite, in the morning go out & play the same note, again recording the tune, date, & temperature. then put a hairdrier in a small room, put the thermometer and instrument in the room & turn on the hairdrier, close the door and keep it closed for about 3-4 hours. After that go back into the room & close the door turn off the hairdrier & play the instruments recording the time, date & tune.

Repeat this about 6 times.

Camilo Lopez required-homestate: US

In the fifth grade I got second place with this topic, Is the strength of a magnet affected more by cardboard, glass, or plastic. first make your hypothesis then start trying different materials on the magnets. Keep trying until the magnets can't hold any more, then measure how much can they hold to see wish material affects the magnet the most.

Natalia from Puerto Rico suggests

I won 2nd prize in the 5th and 6th grade science fair using This question:

To What extent does the humidity affect the growth of fungi? I made the hypothesis. Then I Made a model using the website called only Science fair Projects and the one that I found wasent exactly the same project I used. I hope you can use this information.

Chris Hall from United States

This year for eighth grade i am going to be useing to power of rocketry to mesure the tempreture of an altutude of 3000 feet, over half a mile! I would suggest useing a echostar payload rocket. It is also a double stage rocket to get it up high. The only real challenge is finding a thermoniter fitting on the rocket.

blank from Washington suggests:

In sixth grade I designed a maze for plants to grow through. I got an old box with a few dividers. For each divider,I cut a hole, so that the plant could grow through it. At both ends of the box, I also cut a hole. At one end I laid down a pot with a few seeds in it. At the other end, I placed a heat lamp. Because plants grow towards the sun (or in this case, the heat lamp)the plant twisted and went through the obstacles to get the the other end of the box (and to the lamp). If you need to compare for your science project, try making two mazes(one with more dividers) and see which plant grows through their maze quickest.

Marcus Sanders from Illinois suggests:

The science projact that I 'am doing this year is entitled: A New Compound From Alcohol. Basically I test natural substances, such as air or bacteria, that can cause chcanges in alcohols. A bottle of wine containing ethanol can sometimes be spoiled by such a natural chemical process. This chemical conversion canbe demonstrated in this activity.

Chelsea from Massachusetts suggests:

I won 1st place in my state science fair in 8th grade. I tested the effect of waves on sand buildup. I put sand on the bottom of a fish aquarium and made waves with a board. Then I measured the amount of sand buildup on one side of the aquarium after creating about 50 waves. It was great and I got an A+! ~*Chelsea*~

Foxxy Roxxy from Canada suggests:

I'm doing this idea for a project I'm working on right now. It's great for people interested in Global Warming or the atmosphere. Research on Global Warming. Use jars and fill them up with different kinds of gases that play a part in Global Warming (Carbon Dioxide, Methane, etc). Put the jars under the sun to see which one heats up the most. This way you'll find out which kind of gas plays the biggest part in heating up our environment. I think it's a great idea. My teacher loved it!

Jacque Strapp from MA suggests:

I did a test on whether people actually prefer Coke or Pepsi. First I asked them which they preffered, then blindfolded them and gave them a glass of one or the other, choosing by flipping a coin. I then asked them to identify the product. I found that people who claim to prefer coke can identify it correctly more often, therefore, they actually prefer it more.

Nick Abele from Sumwareinohio suggests:

For seventh grade science fair I tested which kind of household material best limits heat transfer. Fancy way of saying what insulation works the best. Try to simulate a home with a box. On the inside, stuff your insulation and a smaller box to put a thermometer in. Take the outside temp. and compare that to the temp. in each of the boxes. Its real easy and I won $75 at district and went on to state. Now I'm getting all sorts of letters from like Supreme Court people that were blown away with it. Make sure you stress controling your variables, and yes Mrs. Turchetta I plan to work with soybeans this year.

Madilyn from Minnesota USA suggests:

for my science fair project i did "nocturnal to diurnal" or can a nocturnal animal (my pet rats) have its sleeping pattern changed, every night i made my room light and during the day i left the room dark. i did this for ten days, after that my rats were completly changed i recomend trying this experiment if you have nocturnal pets! its great thanks, madilyn

Fer-Fer (LOL) from da best state sunni florida suggests:

my idea is to find out what angle you should put a solar panel under. you use more than one panel and attafh it to a voltmeter or a multimeter that measures the amount of elctricity that the panel is producing. itz also kinda interesting

Samantha from Florida suggests:

Ok, this project got me an A in the 6th grade science fair. My topic was: Which magazine has a better influence on teenage girls? All you have to do is get five different magazines, (like Popstar, Cosmogirl, Seventeen, stc.) and about ten people. Read a certain article in each magazine. Have everyone else read the same article and have them write down what they think about it. Then, make a chart on which articles were better for young teens to read, and which ones had a greater prespective of real life. This should only take about 2-3 hours to do...so make sure you have enough time on your hands. I went to county with this project last year, so I hope if you do it, you'll do good too! GOOD LUCK!!!

aileen mgm from philly by way of la suggests:

does knowledge of calcuim affect calcium intake? it won me 2nd at school and 1st at county along with $200. give one group a class on calcium one group a paper on calcium one group nothing. give them a pre-test & post-test and compare results. judges loved this one. lmyjltacs

Jenny from US suggests:

This is a cool sort of experiment to try:

Do antacids help soil affected by acid rain?

Get a bunch of different pots of soil from your garden or yard. Using a soil sample kit or some sort of acid test kit, test the acidity of the soil. THen put some form of acid in all but one pot of soil (I used sulfuric acid in the form of a pipe cleaner solution) (Mix the sulfuric acid with some water first) Allow the sulfuric acid to completely settle into the soil (I waited about 24 hours!) Test the pH of the soil after 24 hours to determine the acidity of the soil with "acid rain". Then, crunch up a TUMS, dissolve it in water, and pour it into each pot (one or two TUMS per pot). Wait again for 24 hours and measure the pH of the soil.

This is a cool experiment to try...It doesnt take too long and it is really interesting. Good luck!

Travis Clow from Texas suggests:

I really love skateboarding so i chose a project on bearings. I tested to see whether ABEC-3 ABEC-5 or ABEC-7 went the fastest on a regular 7.5 by 31 inch skateboard, it was lots of fun and i did really well in the science fair!

Morgan from Pennsylvania suggests:

My friends sister did this project and I thought it was really cool. How much bacteria is swarming your soda can? Its a cool project but you'll never want to drink a can of soda again without using a straw or pouring it into a glass!

MeGiEz from WV (US) suggests:

what fabric color makes ice cubes melt faster? red,orange,yellow,green,blue,purple,black,brown,white,or none?

Gamaine from Philippines suggests:

The Effects of Monosodium Glumate on Rodents and on Humans based on research and experimentation. the judges liked it a lot. we hardly faced any obstacles in this project. have fun!

Adam from Wisconsin suggests:

last year I did a project about fermentation. I made wine during the process, so if your science teacher doesn't like that idea then leave this one alone. This also takes a lot of work, but it got me an A+. I made different wines using apple cyder, putting a different amount of sugar in each one. I saw how much each of them fermented over a course of about 2 months, then measured that in accordance with how much sugar I put in. I got a 55 out of 50 on the display, too, without really trying.

Anya from california suggests:

You get a person of the opposite gender than yourself, who has the same color eyes and hair, go to the mall (or any crowded public place) wearing same color clothes and ask 25 women and 25 men each for 1 quarter. The idea is to see if people give boys or girls more quarters. Record your results . Be sure to stay away from the same parts of the mall, or people will know what youre doing.

Viv from Canada suggests:

why do acids and bases cause a chemical reaction?

Kathryn Wong from (US) suggests:

Ok, this project is so amazing...simple, yet amazing...You take at least 5 different types of balls...(relatively the same size)-tennis ball, baseball, raquetball, golfball, ping pong ball, etc...and see how high they bounce on a variety of surfaces...(wood, tiling, ceramic, brick, concrete, etc..) Then make a conclusion on why they act the way they do! Good luck. I am trying it this year for state science fair!

alexio from calif suggests:

I want to compare fingerprints within family members(Mo, Fa, 2 children)and look for similarites. How many families should I test? and should I compare the results to random selected people? Thank you for any help in getting the clearest questrion for me.

Shelly Jones from VA suggests:

A great project is "The effect of antibacterial vs regular soaps on the rate of corrosion of iron nails." This project got me 1st at school, 1st at City, 1st at Tidewater and 2nd at VJAS (States for us) back in 8th grade, and a follow up project got 3rd at high school and hm at VJAS the next year. Good luck, but change it a little to make it your own, like test chrome bars or try detergents rather than soaps.

Kdawg from Cleveland,Ohio,U.S.A. suggests:

Set three cups on a flat surface, ask 5 to 10 people to pick cup 1,2, or 3. Put the song "Air force Ones" on while they pick their numbers. My graph showed most people picked 1 because of the song.

aleeza harburger from texas suggests:

1ST PLACE 7TH GRADE SCIENCE FAIR!!!! find out if when 4 mice are kept in a dark environment, and when 4 mice are kept in a bright environment, if they got through a half dark/half light maze differently. i kept the mice in 2 different cages- one that was light all the time, and one that was dark all the time, for one week. then, i put each mouse through a maze that was symmtrical, with one half covered in dark plexiglass, and the other half covered in clear plexiglass. each half had a different opening. i looked for which exit each mouse chose to come out from. JUDGES LIKED THIS PROJECT A LOT

Aydan from Florida suggests:

Observe the manner in which sugar crystals for into the larger crystals found on the coffee-stirring sticks that are coated with sugar crystals that are much larer than normal. (hint-cover the stick in sugar so that the process will be started using the sugar already on the stick as a material for the larger sugar crystals to build on.) You can eat them too!!! :) Aydan Wessels- Age 15

Jessica from US suggests:

What you want to do is find the pH level of soil. You try to find out how acidic or basic the soil is. You can take plenty of samples from different areas of the U.S. You take a little bit of soil and put it in a glass jar and add some water. You then shake it up really well and take a strip of pH paper in the water/dirt mixture. You then skake off the pH paper and compare the color on the pH paper to the color on the key. The key will tell you how acidic the soil is. You can go online and find soil professors and doctors and ask them to send you a sample of soil from where they are and ask for any information they might have. This project got me into the school and regional science fair.

Aubrey Finnegan from Gainesville,Florida suggests:

First you need real teeth out of a human mouth at least 1 or 2 and a caffine drink lets say for example coke. First you take the coke and pore some in a cup any kind of cup doesn't matter at all, then you put the teeth into the cup full of coke and let it sit at least over night or however long you want.when you wake up take the tooth out of the coke and look at the results its going to look a little ROTTEN but thats the point of the project to see the result of your teeth when drinking coke then go wash the tooth off and if it turns back to its normal color you need to leave it in the coke more I left mine in for a week and I one first place blue ribbon in states but my friend left hers in for a day and it worked even though she only won eigth place.

taylor cox from u.s. suggests:

the topic is: what kinds of liquids affect plant growth on wildflowers? On a science fair experiment you have to have a independent variable & a dependent variable! my variables are! Independent: I'm goin change the liqiuds Dependent : the growth of the wildflower plants!! thanks have fun doing my project!!
