Creepy Science Experiments for the Classroom

Have you ever done class rotations instead of having a Halloween party? Where you have a mad scientist theme and in each classroom, you get to do or watch a different creepy science experiment. It makes for such a fun and engaging day, still having fun on the holiday but with a different, twist if you cannot actually celebrate Halloween. I’m sharing with you a bunch of Creepy Science Experiments For the Classroom.

Potions, brews, and eruptions

In these science lab experiments, your little scientists can make their own crazy chemical reactions. The best part is, the experiments are completely kid-safe while also providing tons of fun for kiddos of all ages.
