First up is J-dawg, who will tell you what we made:
We made a cosmic ray detector, how we did it : We got a jar and got a wire hanger . and we put a foil ball on the end of the hanger. We put a little piece of foil on the bottom of the hanger.
(This was J-dawg unplugged and unsensored...thank goodness there wasn't anything about poop in there). Yes, you can all be impressed with his spelling...that kid loves to spell words all...day....long for me. Not bad for a 6 year old!
E-girl will give you the low-down on how we conducted our experiment on static electricity:
To make a static charge, shuffle your feet with socks on the ground or rub a hat on your head. You could also use a balloon. Then we would touch the foil ball to see if it had an affect.
This is the point where Big-Daddy comes down stairs and notices our fun experiment (and he is never one to miss out on a fun experiment). And since our feet weren't quite getting the job done, Daddy brought out the big guns! The Van De Graaff generator is awesome for creating some serious static electricity.
E-boy will now explain what this contraption does when it gets a good static charge:
When the electroscope has a charge the foil in the jar starts to repel. This is what it looks like.
When a charge goes throu the cosmic ray detetor the foil goes apart because they get the same charge.
For some reason, J-dawg refuses to call it an electroscope. I guess Cosmic Ray Detector sounds a lot cooler. There are some differences between them, but it can be used as a CRD if you have that Van De Graaff generator supplying it with a constant charge.
Not bad for a day's work: science AND computerating all in one project! Seriously, check out this link if you want some fun experiments for your kids to try out this summer. Most of the experiments can be done with stuff found around your house. http://www.sciencelearningspace.com/members/go.php?r=5836&i=l22
