My DD8 loves science so we had a science party. It was a lot of work but it was great. We had Jimmy Neutron decorations. We had stations for the kids to visit with an adult helping/demonstrating at each one. They each got a glow bracelet with one of 5 different colors so we could split them into groups and send them to the different stations. At one we made slime and ice cream. At another, they made fossils. At the third, they played with static electricity (plasma balls,etc) and crushed wintergreen lifesavers in the dark (they spark). At that fourth, they made "potions" in test tubes (they added water to Hi-C mix and drank it to see what it was). At the fifth, they observed anatomy by looking through books, viewmaster and plastic replicas of frog and human organs. They also played skeleton hangman. This party was a lot of work but it was the best party my DD ever had. By the way, my DH and I wore labcoats (borrowed from my uncle who is a pharmacist). My uncle also gave us plenty of test tubes and beakers for decoration. This year she wants to do a Harry Potter theme. My mind is just racing on this one. Good luck with the party.
