Comments about Including the Crosscutting Concept
It is important for the teacher to guide the discussions to allow students to not only identify patterns in the food chain but also describe why these patterns might occur and apply this information to new learning and/or through an assessment piece. There are many opportunities for students to make connections between what they have learned about food chains and what they could expect to see in different ecosystems, however the teacher must initiate these discussions. Additional videos or pictures of different environments could initiate such conversations.
