The activities are appropriate for elementary and middle school interest and include many experiments that my STEM school had already planned as part of our curriculum this year. I can’t wait to see the teachers’ faces when I present them with this title. We use the Science NSRC kits and the Engineering is Elementary Kits in our science integration throughout the curriculum. Some of these activities are explored in the kits, but none of them explain and extend the learning in such an exciting way as this series. . . .STEM schools will naturally want to purchase the entire set. It is essential that more school and public libraries carry titles like this.
