I subbed in a fourth grade classroom recently. During a science lesson on electricity, the teacher has me show an old Bill Nye the Science Guy video. I had forgotten about the goofy Mr. Nye, but the kids were enthralled and entertained. We had a great discussion after the video building on what the children knew about electric cars and alternative energy.
Bill Nye is still delivering accessible science information to children. I recently came across a video shared on Rodale News about GMOs and GMO Labeling.
