Activity 6.1: Making Predictions About The Future of Earth’s Systems (30 min)

Students use the long-term trends in the Keeling Curve and Arctic Sea Ice graphs to make predictions about the future.

Resources Provided

Setup

Prepare a computer with a projector to display the PPT.

Directions

1. Use the instructional model to show students where they are in the course of the unit.

Show slide 2 of the 6.1 Making Predictions About Future Earth Systems PPT.

Assessment

Use the students’ ideas in the class discussion to see if they see the difference between short-term and long-term variation and their relationship to predictable and unpredictable projections about the future. At the end of this activity, you want the students to understand why using short-term data that includes a lot of random short-term variation (sea ice extent, sea level, and global temperatures) is not very useful for making precise predictions about specific years in the future, but that the longer-term trends are very predictable.

Modifications

Allow students to visit the following websites to discuss how scientists use patterns in data to make predictions about the future:
