Chemistry 1 – Today was spent practicing using the density models. We whiteboarded practice problems that were comparing mass, volume, and density of different particle diagrams.
Physics 1 – Robot Lab 4! The task today:
- Program one robot to move in at least four distinct segments using a position vs. time graph. (not hard)
- Switch the computer software to show a velocity vs. time graph.
- Use the v vs. t graph to program a 2nd robot to exactly match the motion of the first. (hard!)
Shown above are screenshots of two groups attempts. Group 1 was really confident they had it so they went all the way through. Right at the end of the hour when they tested the two they realized we have some work to do. Group 2 first attempted something like Group 1, but only did the first segment, and realized they had it wrong. They worked hard just to get the first segment correct, which they did. But they still have some work to do on Monday to get the rest.
Chemistry 2 – We took our data from the seven unknown solutions and tried to group like solutions together. Each lab group put their groupings on a WB and explained why they grouped them together the way they did.
