A 3-in-1 Build-upon Kit:1 Car Simulator, 1 Car Simulator with Variable Starting Point and 2 Car Simulator
InterActivity 1: 1 Car SimulatorShow/Hide Scenario
Scenario with 1 car: Everyday Rila drives her red car the 100 mile distance across the flat plains of Flatlandia between the cities AbsolutelyNowhere and BeyondBoring. She drives the whole route at a constant speed using cruise control. A stopwatch displays the number of hours past and a GPS displays the number of miles the car is from AbsolutelyNowhere.
Students build a simulator and answer questions like: Today Rila leaves AbsolutelyNowhere at 9AM. She resets the stopwatch to 0 and she sets her cruise control at 16 mph. What 2 numbers are displayed at 9:45AM? Starting when she resets the stopwatch to 0, every 15 minutes, the car prints out the numbers on the display. What does the printout look like at 9:45AM? What time is it when Rila arrives in BeyondBoring?

Scenario with 2 cars and variable starting positions: Bobi sets out in his blue car at 20mph and a while later Rila sets out in her red car at 25 mph. They are talking on their hands-free cell phones when they both decide to stop where they are. Bobi is 30 miles from AbsolutelyNowhere and Rila is 20 miles from AbsolutelyNowhere. At exactly the same moment, they get back in their cars and both reset their stopwatches to 0 and continue driving at their set speeds. Will Rila meet up with Bobi before he gets to BeyondBoring? If so, when and where? What do each of their printouts show?.
