Halloween STEM Ideas

From icky slime to candy coatings, fake blood, wearable LEDs, a fire snake, and things that foam or glow in the dark, we have suggestions for Halloween-themed STEM to explore with students!

With its emphasis on the ghostly, the ghoulish, the gruesome, the spooky, the icky, and, of course, the sweet (to eat), Halloween brings an assortment of exciting themes to October. Science Buddies has science projects, activities, and lessons that tie in with Halloween and can make for great classroom, home, or independent science, technology, engineering, and math learning opportunities. With a bit of trick-or-treat-inspired thinking, teachers can plan fun Halloween-themed activities for science class!
