These are not regular beads, they are UV beads. They start out a nearly white color and then change in the sun. Luke's teacher from last year, Mrs. Crowder, did the neatest experiment with the beads. She taught the kids about sunscreen. She had the kids put various numbers of sunscreen on the beads. When you take the beads in the sun you can tell which ones have the most SPF protection by the amount of color they change. Luke was beyond excited about this science project! In addition to learning more about how sunscreen works, Mrs. Crowder taught the kids about the various UV rays.
Need a quick refresher course on UV rays or how sunscreen works? Read here.
Need a good place to buy the UV beads? I like buying from Steve Spangler. Don't forget to click on his experiment and video tabs.

Isaac is crazy about science and I never have enough ideas for experiments. I have showed him your posts each day and he gets so excited about them, so thank you for posting these ideas!
What a fun idea -- thanks for sharing them! That's so neat! We have a lot of those "science experiments at home" books and it's fun to try them.
