Here's a FUN, EASY lab to have your students measure the distance an air bubble can travel in a set amount of time. Vary the times, collect data, and graph the results to find the speed of the bubble. Give students multiple tubes that contain different colored liquids and watch the air bubble move at different rates. How does it look if we graph different tubes on the SAME graph? This lab is fool-proof and truly gives students a visual connection of speed shape of the distance vs. time graph.
*You'll need 1 set of tubes for each lab group.
