This introductory unit on the CVPM will proceed along the traditional modeling framework with only a few additions. I expect it to take approximately three weeks. It will begin with the Buggy Lab and whiteboard meetings to analyze the results. The only change from the traditional progression will be to first complete the “Graphing Practice” worksheet from the Scientific Methods unit.
From there they will proceed through the modeling materials for the Constant Velocity Particle Model as provided by the Modeling Materials. Thus the new worksheet 2 will be a worksheet that focuses on the students converting between the position-time graphs, motion maps, and verbal descriptions. Worksheet 3 will then add velocity-time graphs to the mix. Worksheet 4 brings back data analysis and converting to the other representations. Worksheet 5 does the same, but for slightly more difficult situations. We end with additional problems for review.
For those using Standards Based Grading, the first draft of may standards is as follows:
Students will be able to (SWBAT):
- design an experiment that properly controls variables
- report measurements and calculations with proper precision
- develop a mental model that correctly explains and predicts an event
- algebraically solve an equation for a given variable.
- create a scatter plot of independent and dependent data points
- linearize data points
- create a mathematical model of a graph.
- create and interpret graphical and mathematical representations of objects moving with constant velocity.
- distinguish between position, distance and displacement.
- solve problems involving average speed or average velocity.
I’m fully aware that this is a long list of standards, and quite possibly too many standards. Any feedback on whether or not the list should be adjusted (and how) would be greatly appreciated.
