This week in the lab, we are beginning our chemistry/matter unit in grades 1 and 2 and of course, pumpkin investigations in K. We might actually make a pumpkin explode this year. :)
Today, we did "Dancing Creepy Crawlies" in first grade. We replaced the traditional raisins with broken up cooked spaghetti dyed different colors with food coloring. The red ones looked so gross... just like real worms. Mystery potion A was sprite and B was tonic water. They had to determine which made the worms dance more.
