Easy STEM Challenges

Here at Science Sparks we love easy STEM challenges. Not only are they great fun but also a wonderful opportunity for children to work together in a hands-on, collaborative and creative manner to solve a problem.

If you want to make a task more challenging try limiting the materials children have access or setting a time limit.
