Fun Fall STEM Activities for Elementary Kids

Last week, I had a conversation with my daughter that went a little like this:

“Mom, what happened to school?”

I am puzzled.

“The first few weeks, my teachers were so nice, but now, they are getting mean!”

But, unlike my daughter’s teachers, you don’t have to fall into the “mean” trap once October rolls around.

Instead, engage your students with hands-on learning activities, like these fun STEM activities for fall.

Your students will never call you the mean teacher when you bring these educational fall activities to class.
