The Definition Debate
Have students watch the animation for key glossary terms in your current concept. Have them create their own definition using evidence from the animation (Including the text portion of the animation). Have students do a think/pair/share to come to consensus on small group definition. Put all of the group definitions on a bulletin board or web form and have students vote on the best definition. The winning definition will be the one used by the class for the year. For fun get a small little trophy and award the trophy to the winning team. It is amazing how much, despite what they might say, they look forward to holding the trophy for a day or week.
