I was so excited to find out our new elementary school has a Science Club put on by the PTO. Of course, I jumped right in to help and have my girls attend. When it was my week to help, I don't think I realized just what I got myself into! There are a LOT of kids that go to science club. I think I had about 15 kids per group and we rotated about 4 times. I was kind of ambitious and did a fun "Mystery Powders" lab for the kids. We had about 8 different powders including things like Alka Seltzer, laundry detergent, sugar, etc. The kids had to first put a few drops of vinegar in each of their samples and note whether it bubbled or not. Then in a second set of samples, they dropped in some purple cabbage indicator (super easy to make - just boil purple cabbage and save the water - it really cool stuff to use as a pH indicator). The Arm and Hammer laundry detergent was my favorite. It turned bright green. I know, I am kind of a nerd. I love science! The kids then had to use my little solutions page to figure out which powder was which using these two tests. I don't think most of the kids cared to figure this out, they just had fun watching things turn colors and bubble.
Later that night, we used up the rest of my materials from science club and I let the girls mix everything together. They love watching things "explode". (o:

I just realized I never responded to your email...but thanks for the tips on the science day! I'm excited to try them out sometime. This looks really fun.
