Can anyone help me with my science projects???

Question

If you can help, pls tell me what projects to do. I have no idea at all. I need 3 projects (chemistry, physics and biology).For chemistry, i need the one which has some kind of exciting experiment. Physics, I will have to make a sample of sth(e.g. rocket) and it HAS to work. Biology, I have no idea of what is interesting. I am studying in 11th grade. Pls help me out. Thx a lot.

Answer 1

Chemistry -: The famous Diet-Coke and Packet of Mentos trick

Physics-: Make a hydrogen rocket out of a 2 litre plastic bottle, and collect Hydrogen using the collection over water method (straight into the bottle and screw lid on tight.) I would do around 5 bottles to be safe.

For an ignition fuse test differents amount of wire wool, connected to a dc power supply (around 30 volts should do.)

Connect fuse to another screw top, then replace original cap with new + improved fuse cap.

Place rocket on a holder at 45 degrees (do this outside.)
Make sure power supply is set to 30 volts, then switch on - watch that hydrogen rocket go.

Biology -: Not sure, could always do recovery rates of when people have been exercising or something similar.

Answer 2

For physics & chemistry you'll get a lot of answers.
For biology dissect a frog and mount all its parts with their names.You can make the mounting attractive by taking the cross section of some tree trunk ( showing its annular rings) & string the frog (dissected, on it. It shall thus also have a botany input.

Answer 3

For physics, find out different ways in which Lever system is useful in everyday life. Examples such as crow bar, scissors, wheelbarrow can be very interesting to use as illustrations.

Answer 4

You should do something that has to do with volanoes or earthquakes.Try to make a model of a earthquake or a volcano and then get back to me and tell me how it went.
