The effects of microwaves on seed germination and growth. I did this one with both kids - judges loved it!
Get bean seeds and put them in the microwave oven at varying powers same length of time. Of course you need a control group that you do nothing to.
Plant the seeds and measure how long it takes them to germinate and show their little sprouts. Continue to measure them as they grow. Make charts to compare, etc. etc.
