Student Experience Students discuss and evaluate ways to determine the velocity of winding toys. Students experience data set that discusses constant velocity Students analyze a ball rolling down an inclined plane to gather time and displacement data to produce the acceleration due to gravity. Students take part in Galileo’s famous falling objects lab to determine the acceleration due to gravity. (modeling of equation) Students use cell phone cameras to collect and analyze data. T4T Material N/A balls, vertical blinds, 4 in rings Any materials that can be dropped. N/A Big Idea Acceleration Non constant velocity To minimize human error in data points. Connection to Culminating Activity Meaning of velocity and procedure for experimentally determining the average velocity from motion. Plotting data. Students experiment with accelerating objects and changing velocities. *Video Analysis* Students learn that objects fall at the same rate due to the acceleration due to gravity. Scaffold in inclined plane and free fall activity.
