Activity Objective: For students to understand the differences between speed, velocity, acceleration. Activity: Students will work through a mini lab and a worksheet. The worksheet allows them to work on calculations and the mini lab allows you to see acceleration. Materials: • Small ramp • Small car • Time • 5 books Resources: • https: //www. tumwater. k 12. wa. us/cms/lib/WA 0100156 1/Centricity/Domain/1375/ velocity-acceleration-lab. pdf
