Introduction: How long does it take you to react when you notice a change in your environment? If you
are riding a bike or driving a car, how long would it take for you to apply the brakes? Do you think this time is
the same for everyone?
Part 1: Desmos Activity: The Tortoise and the Hare: In this interactive mission, participants use the story of the Tortoise and the Hare to develop a motion graph. Once the motion graph is created, participants will analyze the graph to determine where the motion was the greatest, where it stopped, and where it decreased.
Part 2: The Fast and the Curious
Mission: If you were a timer at a track meet, how would the times you record on your stopwatch compare to the actual
times of the runners?
Participants watch a clip of a race and they have to use their stopwatch/phone to time the race. They are comparing their reaction time with the actual time using a linear relationship.
TAKEAWAYS:
Participants will collect data of speed and reaction time, then present their data by creating and graphing an algebraic equation that compares the actual amount of time
with the average time that you recorded.
