Activity 2.3: Home Groups: Share Expertise (60 min)

Students return to their home groups and share their “expertise” with their peers. They will each report on a different phenomenon.

Materials You Provide

Setup

Get out students’ jigsaw cards and their previously completed 2.1 Finding Patterns Tool for Earth Systems.

Directions

1. Explain the purpose of the activity.

Tell the students that it is their job to discuss the four considerations (generalizability, representation, and short-term/long-term) for each of their phenomena with the rest of the group. Have students retrieve their 2.1 Finding Patterns Tool for Earth Systems. At this point, only the first row should be completed (for Arctic sea ice). Give the students the following instructions:

  • First, experts from Group A will have 10 minutes to explain their phenomenon to the other members of the home group. It is the experts’ job to lead a discussion about what they learned in their expert group.
  • When Expert A is discussing the phenomenon, other members should ask questions if they don’t understand something.
  • After the discussion, the group should complete the row for Group A’s phenomenon, with the exception of the final column.

Ask the students if they have any questions about what they should be doing.

Assessment

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.

Tips

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.

Modifications

After the home groups have discussed the three considerations for A, B, C, and D, have them give a brief presentation to another home group and compare their tables in 2.1 Finding Patterns Tool for Earth Systems.
