When doing a summer STEM activity, I suggest to let the children guide their learning. Avoid jumping in to help them solve the problem or tell what the best solution is.

Through years of doing STEM activities in my classroom and at home with my own children, the best learning comes from children making mistakes, trying a different method and then learning from their mistake.
