Day 67: Projectile Motion Lab Practicum

Today students calculated their predicted horizontal displacement based on the launch location they were assigned and taped their target to the floor (or desk, depending on location). Most groups’ predictions were not accurate. I haven’t reviewed each group’s analysis, but I know that one group suffered due to inaccurate data collected yesterday and another group had accurate data but analyzed it incorrectly. Next year, I may have groups use the short-range setting rather than the medium-range setting to reduce the velocity of the projectile and make the lab a bit easier. One group had solid data from multiple techniques, analyzed it multiple ways, determined which led to the most accurate initial velocity, and based their prediction upon that. They did fantastic:
