Absorption, Heat Transfer, and Insulation
Grade 8•5 minutes•NGSS Crosscutting Concept: Feedback (negative or positive) can stabilize or destabilize a system.
Learning Objective
I can analyze how the absorption of electromagnetic radiation by different materials leads to heat transfer, and I can describe how insulation minimizes unwanted heat exchange, helping to stabilize a system.
