My son and hubby are closer than ever since my husband doesn’t usually get much of a chance to help our son with school work. This helps them both enjoy their love of science together.
Best birthday gift ever! The VR part is totally mind blowing. The app contributes a lot to the fun and learning, but you can still keep it screen free doing just these science subscription boxes.
A great way to incorporate real science into homeschool — as close as having a science lab as you can get at home. Safe and clean to keep parents calm and so much fun learning for the kids!
