In my original lesson plans, I should be through the Magic School Bus Germs kit by now. Instead, Nicholas and I did the vast majority of the experiments just last week. Too bad for us, the yeast that came with the kit had expired (no date on the package, GrrRrRR) and so had the yeast in my cabinet. Needless to say, the experiments did not do what we wanted...the yeast did not react better in warm water than cold because it didn't react at all, it didn't release carbon dioxide to make the balloon fill, and the bread was super dense. Nic still learned a lot, but active yeast would have really SHOWN him what I was telling him. I'm proposing a do-over next week and will also include Sydney - I think she'll like participating. Instead of participating with us this failed time, Sydney instead had her own curriculum about the human body using books in conjunction with a workbook I found on the Fernbank Science Center site , a valuable resource!
In another and much more successful science adventure, the
My plan is to follow up this field trip with some of our own experiments, perhaps getting out so
me more polymer to play with and also getting some growing foam from a hardware store. I also have an episode of Sid the Science Kid all geared up for Sydney to watch that shows irreversible chemical changes in easy to understand examples, like cooking pancakes. HmmMmM...maybe I should get both kids in the kitchen to show them that same example. Sounds like science and home ec. rolled into one breakfast!
