Science fair on Sounds

I'm marjorie , i'm here to help you . It looks like you are interested on doing your project about sounds well i have some great ideas for you,

1. Does sound travel best through liquid, solid or gases?
2.What type of line carries sound waves best?

Hope these two topics can help you. :)

Good luck !

just trying to help
I agree with marj you can also do dose sound distract or help us to focus ( i'm basing it more on music) or why are we scared of some sond and or feel uncomfortable with some, etc. they're not that good it was just some suggestions... :o ;)

heres a catchy experiment...

can You see sound??
The first answer will be ofcourse not but think again...

What u need
loud speaker (or just some speakers)
thermocol *****
tracing paper

begin by covering the speaker with tracing paper. Switch on the music..Full blast...add the thermocol ***** and see them dance....

The sound waves are so strong that they make the ***** dance..
