Sorry. I’ve been really busy, and didn’t notice the thread bumped.
My son wanted to do the electromagnet, but I didn’t have the supplies here, and didn’t have the vehicle until it would have been too late, so that was out. Didn’t have a magnifying glass or too many varieties of cleaners, so that was out. I was actually up for the paper airplane suggestion, but while I was looking on the net, my oldest son found a “make your own plastic” (from milk & vinegar) thing in one of his books, and voted for that. Apparently the siblings were allowed to work in groups, and I didn’t have enough time to help with TWO projects, so we went with that.
After a couple of hours, I decided that I was doing the entire project by myself. I realized that by the next morning, I would have done no studying for my own final the next day; however, I would be an expert in plastics. I told the kids that it was their project. If they had wanted help, they should have told me three weeks earlier. They wanted to fail, they could go on and be free to do so. I was out of it.
Feynn helped them a little later, putting together their presentation, but he was pretty tough, and made them do all of the thinking themselves.
I don’t know what their grade was, but their presentation was nothing compared to so many of the other ambitious projects. Hey, what can I say? I only had four hours notice.
Thanks for the suggestions, everyone. And thanks for checking on me.
