The STEM lesson for 2nd grade incorporated using Ozobot Robots to teach States of Matter & Mapping Skills. I first learned about Ozobots this past summer. I caught the Amazon Prime sale and purchased two for my kids as toys. Little did I know the impact it could have in the classroom! 2nd grade students had just completed their unit on States of Matter, and I was looking for a way to incorporate my new ozobots I won for my school, and I came across this great blog post by Kim Mattina in which she used Ozobots with middle schoolers to program the States of Matter. I modified the lesson to address curriculum objectives for 2nd grade, and then along the way, I found a way to connect it to their mapping unit too.
