Halloween STEM activities for 3rd grade are a fun way for 3rd graders to explore science, technology, engineering, and math during Halloween!
There is something magical about Halloween when you are in third grade.
You’re finally old enough to understand everything about the holiday, but you’re still young enough to get swept up in the magic of it all.
That’s one of the reasons why third graders are some of my favorite age of kids to work with!
In third grade, kids are curious and love learning about the world, which is why I always love doing creative STEM activities with third grade kiddos!
This Halloween, why not try out these 3rd grade STEM activities for Halloween?

How to Do Halloween STEM Activities in 3rd Grade
In third grade, STEM is all about applying scientific thinking and concepts to real-world issues, and learning more about how the world works!
Although these Halloween STEM activities aren’t exactly “real life” they provide a fun hands-on way for kids to explore the world and gain an interest in science!
Third graders will love these hands-on and just a bit silly science experiments and STEM projects which can help them build a love of science that will carry them through the high school years!
My two girls (9th and 3rd grade), have both done STEM activities all their lives and they always excel at science and my eldest is thinking of pursuing a career in a STEM field thanks to a lifetime of hands-on science!
