Solar Cooker....

Life in the "classroom" is never boring...

I saw this project on solar energy for cooking where you line a box with foil and black construction paper and according to the wonderful instructions you should get enough energy to cook something.  Well, it didn't work at all.  We had marshmellows set up trying to cook them...

So, there's more then one way to harness solar energy so I gave the kids magnifying glasses to try to get it to work that way.

Well, one student showed how to make these solar cookers work.  Set it on fire with the magnifying glass...

Gotta love it when you students set their science project on fire... At least the marshmellows cooked then...

dwot, don't use paper, use a thick plate of copper painted black - you will be able to fry an egg.

adventures in education. one of the funniest thing i ever saw was on a NOVA program about building Machu Pichu. due to the tight fit of the stone work a scientist suggested that the ancients had used a parabolic mirror to "melt" the stone with focused sunlight. using such a device, he attempted to ignite a popsicle stick on a bright sunny day. the stone mason said after 20 minutes "this guy can't light a match!" and went back to scribing a block to fit. very funny, might have lost something in the retelling just now...
