Presentation transcript:

Jan 16 / 17 Act D 57 The Conservation of Energy LEARNING TARGET: I can demonstrate a basic understanding of the Law of Conservation of Energy CH Q What is the guiding principle behind the behavior of energy? VOCAB: (next slide)

Law of Conservation of Energy amount of energy needed to do an amount of work Efficiency Scientific Law Law of Conservation of Energy cause and effect observations (NOT How or Why) amount of energy into a system equals amount that comes out

DISCUSSION ability to do “work” can be transferred or transformed Review: What is Energy?

PROCEDURE AND DATA MATERIALS: PROCEDURE: Read on pg. D27-30 silently - after reading each paragraph, write a summary sentence about that paragraph. (there are 10 paragraphs… so there will be10 summary sentences). DATA: WS 57.1 Conservation of Energy WS 53.1 (update)

POST DISCUSSION Review answers 3-5 on WS 53.1. Do you still agree? Disagree? Add more evidence to support or change your answers.

Review answers 4 on WS 53.1. Do you still agree? Disagree? - Add evidence to support OR change your answers. - Add the pg in the book where you found your evidence

ANALYSIS - Discuss and answer Q 1, 3, & 5 on pg.D 31 ANS CH Q What is the guiding principle behind the behavior of energy? A: it can be transferred or transformed BUT NEVER created or destroyed (Law of Conservation of Energy) *there is a Law of Conservation of Mass too, remember E = mc2 (Challenge – How are they related???) HOMEWORK Look for and collect at home, items that could be used as insulators - NOT a commercial insulator - thermos / cooler / etc
