Days 39-40: Lab Performance Assessment
We spent these 2 days (3 periods) on a lab performance assessment. It was split into 2 parts: an individual portion and a group portion.
The individual portion had 3 tasks:
(1) Find the speed of a green buggy using a stop watch and meter stick;
(2) Find the speed of a green buggy using a motion detector and Lab Quest 2;
(3) Find the speed of a green buggy using video analysis in Logger Pro.
I had 4 stations set up for each of the 3 tasks. Students spent about 20 minutes at each station and rotated through. (The video for the video analysis task was pre-made by me.)
The group portion had 1 task: Design an experiment using a pull-back truck to find a mathematical model relating 2 variables. Students worked in groups of 3 and had 60 minutes to complete this task. They could graph their data by hand or use Desmos.
Half the class spent the first 60 minutes of the 3 periods rotating through the 3 individual tasks while the other half worked on the group task. Then they switched for the remaining 60 minutes.
