The document describes how to incorporate cooperative learning techniques into a unit plan for teaching students about separating mixtures. It recommends organizing students into groups of 6 and using two cooperative learning techniques: 1) A jigsaw activity where each student researches a different separation technique and becomes an "expert" to teach their groupmates, and 2) A round robin activity where students take turns sharing their views and strategies for separating a mixture of sea water and sand in a lab report presentation. The document provides detailed instructions for implementing these techniques.
