Day 1 - the classes watched the videos about Groundhogs and if needed, light and shadows.
Day 2 - classes came to the library to design and construct their winter scene dioramas in small groups. 3Dux had kits that you could purchase, but you could use your own materials too.
Day 3 - classes came back to the library to put their Groundhog in their scene and shine their light from different angles. They observed what happened to the shadows. We didn't record data this year, but we'd like to try that next year.
The learners had a blast creating and building together and the teachers and I loved collaborating.
