Lesson Plan

Entry Work Question: Define global warming and the greenhouse effect!

Attention Grabber: Explain the difference between Global Warming (unnatural - from pollution) and the Greenhouse Effect (think GREEN - it's natural and all planets need it to survive!) - review these terms from yesterday.

Introduction: Have the students take turns reading through the background and instructions for the topics covered on the graphing exercise on page 380. Don't forget that they have to do questions 1 and 2 on that page as well!

Together Work: What is the first step to setting up a LINE GRAPH? What is the very first thing that we need to do? We need to draw and label the X and Y axes. These are the years and amount of CO2 in the air. Watch me as we go through the first 5 years and I show you how to estimate where the amounts of CO2 are on the graphs.

Independent Work: To review for the test, the students are to work on Pg 382-383, #1-24.
