Now that school has started, and we’re starting to get into the swing of things, I realized Halloween is just around the corner! I love to perk my sons’ interest in Engineering by doing fun experiments to tie in with upcoming Holidays. For example, near the fourth of July this year, my son experimented with water while making an American flag. I also want to have fun with some Halloween science experiments, but instead of coming up with my own, I decided to find some experiments from fellow science bloggers. I was amazed at the creative experiments that explored all areas of science, from circuits, to buoyancy, and even magnetism! Here is my list of over 20 fantastic Halloween Science Experiments to try with your kids!
