Ectotherms & Endotherms

Learning Objective Success Criteria Know about endotherms & ectotherms Describe the physiological and behavioural responses that maintain a constant core body temperature in ectotherms & endotherms

Starter: Marine Iguanas http://www.youtube.com/watch?v=czpPbDG HOZA

Task: Independent LEarning Person 1: How do Ectotherms maintain a core body temperature? Physiological Responses Behavioural Responses Person 2: How do Endotherms maintain a core body temperature? With reference to peripheral temperature receptors, hypothalamus & effectors in skin and muscles Create A4 summary with question on either endotherms or ectotherms, must include definition of those terms. Use pages 8-11 in book.

Assessment Plenary Explain the key points to the other person in your pair Can they now answer the questions on either page 9 or 11?
