Transformations in Matter and Energy Carbon TIME is an NSF-funded partnership led by Michigan State University
Human Energy Systems | Activity 2.3
Target Student Performance
Students return to home groups and share their expertise about patterns of change for four variables in Earth systems: global temperatures, global sea levels, Arctic sea ice, and atmospheric CO2 concentrations.
Resources You Provide
- 2.1 Finding Patterns Tool for Earth Systems (from previous activity)
- 2.1 Assessing the Finding Patterns Tool for Earth Systems
Get out students’ jigsaw cards and their previously completed 2.1 Finding Patterns Tool for Earth Systems.
Use your time circulating through the groups to determine what ideas may be more challenging for students. It may be that in some groups they are easily able to spot the long-term trends but they have a harder time describing the short-term variability, for example. Use the 2.1 Assessing the Finding Patterns Tool for Earth Systems to assess how well they understand the four considerations for each phenomenon.
Identify which idea students struggle with the most in the home group discussions and pull these ideas out to discuss as a whole group. Encourage students to ask questions about things they don’t understand in their home groups.
Tell students early that they will leave the far right column blank during this activity.
