Next year science teachers at my school need to provide 2 periods of science enrichment per 6 day rotation. I don't know if there will be a budget for supplies. Right now, I'm gathering ideas. I would like the experiences to be authentic. They can be single period activities or span several periods. I might not have the same students each of the enrichment periods I have. (It's complicated!) Do you have any ideas what would be exciting, the kids would like and gain from? Thanks!
