For your next science experiment, use the Scientific Method Poster and Recording Sheet.
For a fun idea using Lab Coats in the classroom:
When I was teaching 3rd grade, we asked students to bring in an adult white; button down; long sleeve shirt. When it was time for science, the students put on their white shirts, or "Lab Coats". The classroom looked like a bunch of tiny scientist with their lab coats on! It brought life skills into the classroom and the students loved it too! There was such a fun vibe in the classroom.
