Today the physics classes put together their graphs and linear functions to come up with a model for constant velocity. Whiteboard discussion was actually pretty good considering we have 30 kids per class.
While many kids really had to wrap their heads around the physical meaning of their graphs (slope and intercepts), the actual physics of CV is a bit too easy for them. They’ve all been exposed to constant velocity in science 10, and have also probably approached similar data and functions in math 10.
In this example, we had a good discussion on significant figures (again), but this group had a pretty good handle on what their graph was telling them.
