Thank you for sharing this resource. I like the alternative and safe way of the cabbage indicator that was included in the description. Very detailed and easy to follow!

Excellent introduction to learners as well as K-4 Science or Math Educators. Materials are easily attainable. Detailed teacher plans and background knowledge. I scored this activity a 3 star because students activity sheets would need to be modified for K-1 learners. Also, no student technology links or real life connections were suggested.
