phsyics project help? 10 pts best answer?

Question

i have no idea what to do for my physics project, i've tried googling some topics but some of them seemed a bit too far complex

i'm a high school junior and i need a good creative physics project

any sites/links with procedures or ur own ideas would be very helpful

i also have to make with home made materials

Answer 1

Do a buoyancy experiment.

f = ma = W - B; where W = mg, the weight of whatever you might try to float in a bucket of water; m is the mass of the object. B = rho g V; where rho is the mass density of the water, g = 9.81 m/sec^2, and V is the volume of water displaced by the object you try to float.

When W = B, the object will float; when W > B, the object will sink. Try several objects, but make sure some sink and some float. Use the equations above to specify why some sink and some do not...they float.

If you top off the bucket and put a dish under it, when you place the object in the water, the water will spill over into the dish. Pour that spill over into a graduated beaker to find out how much water was collected. That will be the volume V of the object because that's how much water it displaced.

And, if you really want to get into this, repeat the objects but with different fluids (e.g., kerosene, oil) You may find some of the objects that sunk in water will float in the other fluids...explain why.

Answer 2

You might like to read Science Fair Projects for Dummies probably available at Amazon.com. I read it. It is pretty good. It also goes into how to present your project. This link also list other project books.

Answer 3

Prove the Isaac Newton Momentum Equilibrium and Conservation Theorem.

Try building a 4'x3'x2' post/beam/stud box-frame and add continuous reinforcing steel net to interior side of boxframe. Show how much force it will take to break apart the boxframe or build an additional boxframe without continuous reinforcing steel net, and compare-test the two boxframes to see which one will last longer under various tests. Try pushing the frames apart, pulling the frames apart, and crushing the frames. You can pick up the general ideas for the boxframe construction on the yahoo website Tor-Eggs-Tor design Solutions with Closed-Nets. Please let me know how the experiments went.

Answer 4

While this will take a little digging on your part, I would recommend that you consider a project demonstrating the operation of a vacuum tube, and a modern Field Effect transistor. In actuality, the properties of the 2 are quite similar. A point to consider on this is how much our present relies on the foundations laid by past technology.
To supply power for the tube, if you decide to do this, can be done by using simple batteries since you won't need to draw a lot of current. 9 volt batteries can be connected together to make a very effective plate power supply for the tube, while 1 or 2 can be used for the transistor.

Answer 5

The project is to make a metal sphere about 1meter diameter and put a small hellicopter in it to fly,and observe the difference.
