25 min

Preponderance of Evidence Activity - Students should be divided into groups. There are 8 different cards. Students will review the cards for their group, discuss the evidence, and then listen/give presentations and take notes on all the other evidence.

15 min

A Process of Science- Teacher presents and discusses the process of science, scientific consensus, science in policy, and political interference in science.

5 min

Video of Commercial on Carbon Dioxide- Teacher plays video without much of an introduction. After viewing the video, the teacher asks for initial impressions.

PRESENTATION5.1.4 Process Science SLIDES

10 minStudents work in groups to analyze the commerical using the transcript and questions on a task card.

Day 2

3 minBellwork: Perhaps you have heard debates about global warming. Write down different arguments that you have heard in the media about global warming.

5 min

What are some of the major debates over global warming that you wrote down for bellwork?- Have students share what they have heard and where they have heard it. Write some of these ideas on the board and note the sources.- Tell students that they will be watching segments from a video called "The Global Warming Swindle". On their handout, they will be asked to write down some of the major arguments that the video makes. They can also write notes about what they think about the argument to the side as they will be talking about these in groups after the video.

20 min

Watch Global Warming Swindle Parts 1 & 2- Use the note guide to write down the major arguments that the movie makes.

8 min

Teacher-led Discussion- Based on your note guide, what are some of the major arguments that the film makes?- What are their sources of evidence?- What is your response to these claims?

14 min

For example, the scientific consensus supporting a geocentric model of the solar system and the fixed-plate theory for the earth’s crust were both

overturned. The geocentric model was replaced when observation, physics, and mathematics advanced to the point where a more accurate, heliocentric

model could be produced. Mounting evidence against the fixed-plate theory overturned this incorrect consensus and gave us our modern theory of continental drift.
