This task can be done virtually or in person. Since my classes are 100% virtual this year, I had groups in breakout rooms on Google Meet with a shared jamboard to show all of their work. They submitted their shared google doc and jamboard for grading. I decided to have a little fun with the video since I knew they would be spending a lot of time with it. :) The video includes information about my mass, the slope of the hill, and the distance travelled (ruler overlay). To get the best timing results, students can download the video into an app like Hudl Technique or Pivot Interactives. The TaskUsing the video, calculate as many physics properties as you can that incorporate our topics of Motion, Forces, Energy, and Momentum. Some properties are very easy to measure or read from the video (mass, angle, etc) while others will need more calculations (kinetic energy, normal reaction force, etc). For properties that exist throughout, you are only allowed to include in two locations (i.e. initial and final momentum) Show all calculations and record your final answers in the table. The first few rows have been started for you but you will need to add in the others. Only answers within the accepted range of uncertainty will be accepted in the final count so it’s a good idea to aim high
RubricThe rubric is a pretty straight forward 10-point assignment that awards points primarily based on the number of properties that each group correctly calculates from their measurements. I found that 18 was a pretty good threshold with the content that we had covered (most groups submitted 20-22 for a buffer) but it would be really easy to adjust this based on the placement in the year and the topics that have been studied. CalculatorSince there are a variety of different values that could be calculated and their values are dependent on the groups displacement and time measurements, I created a calculator in google sheets to enter their measurements and automatically calculate all of the properties that I anticipated groups would include. They didn't have this list of properties, so their presentation of the values was far less organized than this ;) Individual Make UpFor students that missed the lab practical day and didn't have the opportunity to complete this assignment in a group, I created a "make up" assignment with reduced requirements. This allowed individual students to have a similar experience as their peers but at a more appropriate level for a single student to complete without the help of a group. Rather than expect a total of 18 properties. This make up assignment has a list of 7 properties that are required followed by 8 more optional properties. To get 100% students must correctly identify at 12+ properties. Click Here for More Labs
