We are using Master Books 9th grade curriculum for Fall 2015. In it is a science curriculum that includes Engineering (Based on God’s Design) and I thought “What if I found a monthly subscription that would send my teen boys little things to build and tinker with? It would go well with the curriculum and be fun!” So, Google search brought up Kiwi crates and I got $10 off 🙂 You can to!
