Halloween STEM activities for 4th grade are a fun way for 4th graders to explore science, technology, engineering, and math during Halloween!
If you teach fourth graders, or are parenting a fourth grader, you know they are still curious about the world!
That makes this the perfect time to pique their interest in creative STEM activities.
No matter what time of year, I love using seasonal STEM activities to capture children’s imagination and get them to think outside the box.
My goal is to teach kids to be innovators, problem solvers, and creative thinkers, and I believe that hands-on STEM activities are one of the best ways to do so!

How to Do Halloween STEM Activities in Fourth Grade
In fourth grade, kids are old enough to do most of the activities without help from an adult.
I always introduce the concept before I hand out any supplies to kids, and I like to have fourth graders work in small groups when they can.
In some cases, it can be helpful to assign roles to the students, like one is the designer, one is the recorder, and one is the engineer. This can help keep kids on track and prevent conflict.
Fourth graders should be able to apply scientific concepts to their problem solving and draw conclusions on their own.
I don’t like having “right” answers in STEM class, as there really isn’t right or wrong in science, only experiments and hypotheses.
One importnat element to include in fourth grade is a science journal, or a STEM activity worksheet. You can get our free version below.
