Bumper Buggies requires two constant velocity buggies, some pre-assigned starting locations, and a little bit of math.

On Day 1, students used video analysis to determine their buggy’s speed. Today, I assigned two lab groups to play Bumper Buggy against each other. Both teams got a starting point and were asked to predict a collision location (and time). I didn’t tell them how to do it.

The group in the following video used a graphical method (shout out to Desmos — it was the kids’ introduction to the world’s best graphing tool).

Another student used algebra to predict a window of times between which the collision would occur (as in, her prediction sounded something like “the collision will happen between 1.7 and 2 seconds and between 1.1 and 1.3 meters from the blue buggy”).
