how dou you build solar eclipse.?

We Answered:

make a basic frame set out of the wood then draw the sun in lightly with yellow crayon on some grease paper, stretch the paper over the frame and you could shine a torch at the back of it .
Take some black card and cut ot out to match the size of the sun, you could glue a straw or lollie stick to attatch, the move the black card in behind the sun to eclipse. Best i could think of!

How can i build Solar Powered Water Heater model?

We Answered:

Simplist is to use a box with coils of black rubber hose in it,Slowly pumping water through it will gove hot water on the output if it is a bright day. To make a model, just use a heat lamp for the source and small black tubing and something to show temp in vs. temp out.
