I am i freshman in highschool and i need a science fair project so does anyone have any ideas for me?

Question

Can anyone provide me with a great topic or idea for a highschool science project?

Answer 1

Yes, I have a killer project for you. If you were to pull it off, you would be a very popular person in school. You may need a little trigonometry or some geometry to work it out.

You will also have to get a layout of the U.S. Pentagon: Maybe some satellite pictures.

Your challenge would be to try to figure out what size "plane" hit the Pentagon.

You could use the profile of a small craft seen in the released video of the attack. Here is a profile of the craft that hit the Pentagon.

Good luck.

Answer 2

well thinking of that last answer doing the things that i do hs made me a really cool guy in school and i was thinking of building a speaker
yeas you heard me right a speaker it seams hard but it's no big deal they are very simple to work with
(this may take a few trips to radio shack)
so i might have a deign for you and i'll host it right now
for info on how these things work gor here

WARNING!!!
this has an impedance of <1 ohm so i recomend testing it's ohmage so whatever the ohmage you should increase it to at least 8 ohms but the resistors should go on both loose hookup wires and the value that you want to add might need to be divided by 2 (we're talking about an ac current here as in it goes in different directions in the same wire so to make sure that it resists enough energy to keep things safe make the values divided evenly, and this is to ensure that it get resisted when electricity flows in either direction) but if they come out as decimals then one can be bigger than the other.
atleast it resists like if the speaker had 1 ohm and i was to add 7 (adding that requires decimals) so a 4 can go on one side and a 3 can go on the other see where i am going with this

heres the design

and i asure you that this is very simple but you might need some help connecting it to an mp3 player or something (not very many people know how to ground it or what ground means, but i can teach you)

if you need help contact me at [e-mail]

Answer 3

It depends, but you can talk about ''Reproduction''.
