In a nutshell, we had cups of water sitting underneath different wattages of light bulbs. Our hypothesis being more water would evaporate when exposed to more heat/energy. So much better than germinating seeds! His teacher would be so impressed!
I gathered up our supplies. I went to OSH ("The answers are out there. We'll help you find them") and asked someone there how to wire up what I needed. No problem.
His teacher went to plug it in and a huge arc of sparks shot out of the connection, leaving a little burn mark on the box. Oops. One of the dads saw it and pointed out that I had left something exposed when I connnected the socket to the power cord. After 2 more people pointed out how dangerous it was, we left it unplugged.
We wrapped the wires with electrical tape (I figured that had to be the correct tape to use, right?) so that Zach could plug it in when he presented to the class the following day. I wasn't there but Zach brought the contraption back with one of the plug prongs melted. I guess the tape didn't work. I didn't ask for details.
I have no idea what went wrong with it. It also freaks me out to think I had them plugged in the house for all that time. Thankfully Zach and I didn't burn the house down! I have 3 years before Joey has to turn in a science project. Maybe I will stick with the germinating seeds.

I would have thought electrical tape the way to go too. Despite the sparks, it looks like Zach got all the details of the real experiment down on his presentation board. Cool idea!
I can't do 2nd grade math. Don't feel badly.
And I like seeds. Nothing wrong with seeds.
I'd opt for the culturing stuff on petri dishes. But that's just me.
