Day 2: Identify Key Variables
After "messing about" with model parachute materials during Day 1, Goldman brings together teams' disparate experiences with the task by having a discussion of what teams noticed were key design variables in their model chutes. After the discussion, students go back to work. Watch Movie 2 for signs of any impact on groups' discussions about their next steps? Also, compare this discussion with those of two science teachers on Identify Key Variables. Did you identify other variables that these students missed?
