Today, I’m celebrating the fourth grade with these Valentine’s STEM activities for 4th grade! It doesn’t get much more fun in the classroom than when kids are doing hands-on Valentines STEM activities. I love 4th graders. In 4th grade, kids are mostly independent, but they don’t have that tween and teen know-it-all spirit that can get a little tiring. 4th graders aren’t ready for true love, and they are a bit beyond classroom valentines, so there is a bit of a void on what to do with 4th graders on Valentine’s Day!
These Valentine’s Day STEM activities for 4th grade were collected with 4th graders in mind and are perfect to do in a classroom setting, STEM lab, or at home with 9-11 year olds.
