Though my experience is mostly in the fields of electricity, magnetism, and physics, I have a broad science background. My career is in the field of alternative power sources -- solar, wind, water and battery power. But any questions about electricity, magnetism, energy conservation, power generation, electric motors, and even general physics are very welcome--especially from kids. They ask the best questions of all! I pride myself in answering science questions accurately, with ideas for SAFE, easy experiments that kids can perform by themselves--and that let them prove the answers to their own satisfaction. I think science should be fun, and available to everyone, regardless of age.
I have volunteered in our local public schools for 5 years. I currently make presentations at our schools about electricity and magnetism, with a focus on solar, wind, water and other alternative power sources. I try to demonstrate at our schools how easy it is to make electricity, with simple devices using spinning magnets and coils of wire--powered by wind, water, bicycles, gerbils...etc. And of course solar panels! I am the webmaster of Otherpower.com, an alternative energy website. I have lived 10 miles from the nearest power pole for 11 years--I make all my own electricity from scratch with sun, wind and water.

Hello David -- It's not a daft question, but it won't work. There's not enough energy potential from skin electrodes to power anything...the voltage ranges from microvolts to millivolts, but the amount
Hello Kara -- The online Wikipedia is actually very reliable, at least with well-known science topics. When you move into fringe science, there are some nutty things on there. But the Evaporation article
Hi John -- You want an LCD clock, *not* LED. LEDs use too much energy. You can get one at any K-mart, Walmart or supermarket. Pick one that runs on a single AA or AAA battery, so the voltage is 1.5v
Hello Anne -- Bubbles are actually fairly complicated things, they are thin films of water. It's really the protein in milk that does it -- your other liquids don't have any. Protein is dissolved in
Hello Georgina -- According to the theory, there was no dust, ice and rocks -- there were not even any atoms at all! -- at the time of the big bang. It was an explosion of space itself, and at that
