Day 20: Board Meeting & Free Fall

Physical Science: Newton’s Laws Board Meeting

Students finished collecting data, then we had a short board meeting to agree on the qualitative relationships in Newton’s 2nd Law.

Physics: Free Fall

Students white boarded answers to a few qualitative questions about last week’s Direct Measurement Video. I emphasized having them provide evidence to support their answers, which lead to some good conversations, both in groups and in the whole class, about what makes “good” evidence. Different groups looked at different combinations of falling objects, which lead to some good disagreement about whether all objects fell at the same rate. My favorite moment was when I asked whether using the same acceleration for all objects is useful and a student quickly responded with “It depends” which lead to some good talk about uncertainty.
