Explore Simple Machines — Elementary STEM Unit Study | Knowledge Crates

The best.

My daughter loves stuff about simple machines when this came in she went straight to building. She learned new ways to incorporate this into other things she has built

Another Amazing Crate!

The books chosen to correspond to this curriculum are absolutely amazing! My son loves the projects & we’ve both already learned so much!! TY knowledge crates!

Hands on

We love all the hands on activities/projects that came with this box and also that the simple machine cards give real life examples of each one. As a public school mom I love to help expand my children’s knowledge when I can and these boxes really help with that!
