This lesson uses the "Play-Debrief-Replay" model of science education, as described in "The New Teaching Elementary Science" (see resource).

Students try one activity, then the other, then gather to debrief.


An hour and 20 mins is not enough time to include the Replay aspect of this lesson. Either add time, or remove one activity.
