Public Policy Analyst (PPA) 1. Define the Problem 2. Gather the Evidence 3. Identify the Causes 4. Evaluate an Existing Policy 5. Develop Solutions 6. Select the Best Solution (Feasibility vs. Effectiveness)

Step 1. Define the problem

Form groups of three students. Make observations of the image. Come up with your own definition of global warming.

Global Warming The planet is heating up - and fast There are global weather patterns, especially increases in temperature and storm activity. Greenhouse effect is a major cause.

Step 2. Gather the evidence

What is similar in the graphs?

We know global warming is a reality because: Global temperature rise Warming oceans Shrinking ice sheets Glacial retreat Decreased snow covered Sea level rise Declining Arctic sea ice Extreme events Oceans acidifications

Use the internet, in your group, complete Worksheet # 2. Gather the Evidence: Worksheet #2

Step 3. Identify the causes

Are these images familiar?

In your group, complete Worksheet # 3. Identify the Causes: Worksheet #3

Step 5. Develop Solutions

Some Solutions Shift the way humans make and consume energy (renewable resources). Plant more trees Reduce the amount of greenhouse gases

In groups, brainstorm possible ways in which students at your school can help reduce the problem.
