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

Resources Provided

Setup

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

Directions

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

Show slide 2 of the 2.3 Home Groups: Share Expertise PPT.

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.
