In this lesson students: 1) share what they think they know about why animals live in groups, 2) watch a Powerpoint to stimulate their thinking and engage their interest, 3) review what they’ve already studied about animal groups, 4) are introduced to claims, evidence and reasoning (with examples), 5) share their ideas about why animals live in groups (sometimes acting out their ideas), 6) read short passages about animal groups, and 7) participate in a science talk to share their claims based on the evidence they have gathered about how groups benefit some animals.
