Other Considerations

Grouping Suggestions: Be aware of students' abilities and ethnic backgrounds when choosing groups. Try to place students of varying abilities and backgrounds in each group.

Pacing/Suggested Time: This activity will take several 45 minute class periods. It will probably take 1 class to perform the Engagement activity and make the first set of putty samples to be tested. It will take a second period to test the samples, record and graph data, and plan the mixtures each group will try when allowed to create formulations on their own. A third, and possibly a fourth class, will be needed to test the new formulations, draw conclusions and write the assessment report.
