Well- it’s that time of year again- Halloween is approaching and there are some wonderful ways to connect the excitement of Halloween to engaging science demonstrations and investigations. Here is a list of some of my favorite links:
The Haunted Physics Lab– another source of ideas.
Halloween Science at Science Bob’s Site– even more videos and projects.
Easy Halloween Science Experiments for the Classroom– the title says it all.
Icky, Creepy, and just Plain Gross Science Projects– a page from Scholastic with lots of gross ideas- boys will love these!
Spooky Halloween Science and Halloween Science Experiments from the Kitchen Pantry Scientist Blog- a very cool site by the way.
Science for All 
Thank you for including Steve Spangler Science in your Halloween experiment list. We love Halloween science!
