Assessment
Use the ideas students share during class about ecosystems to formatively assess their familiarity with various ecosystems, types of organisms, and organic versus inorganic carbon.
This Unit builds on previous knowledge about organic versus inorganic carbon and systems at different scales. If students experience difficulty making the connections in this lesson, they should be provided further instruction or review before moving on. See particularly Lesson 2 and Activity 5.3 of the Systems and Scale unit.
Tips
Check to see if students are able to identify the difference between organic and inorganic carbon at this point in the unit.
