Does anyone have an idea 4 a science fair project on at least an 8th grade level? (preferably physics)?

Question

I am in Honors classes at my school, and we are required to participate in our county science fair. I was wondering if anyone had any INTERESTING and EXCITING ideas for a project. It has to be at least on an 8th grade level, and preferably in the physics area of science. Here are some of my interests which might help come up with an idea: cooking, basketball, singing, softball, track, and music. (this might help a little) But if you are unable to come up with a physics based project, I will accept any help at all! Thank you.

Answer 1

Some one asked the other day on here about the wives tale of hot water freezing faster than cold water... There is no clear reason why it works, but experimentation seems to show that it does... hows that for a topic?

The argument against usually goes like this -- If one batch of water is at 100 degrees, and the other is at 50 -- well, when the batch at 100 lowers itself to 50 degrees, then it will act just as the other batch from then on... makes sense, but seems to be wrong in practice... why?

Answer 2

U like playing basketball and soft. A very important related to these game is the projectile motion of the body under gravity.
U can also use basketball as an project defining example.
This might just become too high for ur gade.

Answer 3

You can do lots of fun things with springs. You can test hookes law, which says that if you hang a different weights on a spring the length of the spring will change in proportion to the weight you can demonstarte the wave motion of a weight bouncing on a spring, called simple harmonic motionand show tha you can make the weight bounce very high if you give it energy at its fundamental frequency, just like pushing somone on a swing.

Answer 4

Singing and music are several of your interests; so I would suggest a science project about sound waves. Possible subtopics: Ultrasonics, infra-sonics, and the acoustical sounds made by musical instruments; as well as the human voice.

Answer 5

You could learn how to throw a curveball, and explain how it works, make it curve in different directions depending upon the speed and spin.

Music--waves, how the frequencies depend upon the tuning, how the sounds of drums change when you tape different parts of the drumhead--or even the wave pattern in the drumhead. Or how the tone of a drum changes when the geometry of the drum changes. Or how the temperature of the air in a flute changes the tuning...

Answer 6

Here are some ideas

01. Fuel Cell (Chemistry, yet very intereseting)
Produse electricity with water and platimun rods

02. Aerodynamics (Physics)
[One of the harder challenges]
Drawing/Designing different plane models and proving which one flies the best.

03. Quantum Mechanics
Show and explain the Reed Motor

Let me know if you win. Best of Luck

Answer 7

I had to make an original musical instrument and test the sound waves back last year. It makes use of the concept of sound, sound waves, etc.

But it is quite small, so if you want a bigger project you might want to consider making a few instruments using the various methods of sound producing: etc, wind, reed, percussion, etc

Answer 8

Well i don't know know but i did this one when i was in 7th or 8 th grade & got 1st place,

1.shred a end of a extenchen cord
2.get a dill pickel (lots of juice on it or it won't work)
3.stick 2 nails in each end
4 wire each end to the nails.
plug it in and watch it glow....

Answer 9

I just did a project on whether dogs can comprehend the difference between two different musical notes and completely blew away the judges. i did mine a lot like the pavlov's dogs experiment (you might have to look that up). its actually really easy to do if you have a dog.

Answer 10

make a volcano.
