Physical Science: Redesign

Now that groups have a plan for how they will test the second iteration of their design, they worked on actually planning that design. Compared the first time around, there was a lot more conversation about the different ways designs could fail. There was also a lot of talk about what had and hadn’t worked in the first iteration. At the end of the hour, each group paired up with another to share their testing plan, their design, and a justification for their design.
