Your Task
Design a track for Cue. Use what you know about the relationship between distance, time and speed to determine how fast Cue can get around your track.
Hint: when you ride in a car, speed is measured in miles per hour (mph)

Directions:
Use tape to lay out a track for Cue on the floor of your classroom or in the hallway.
Measure the distance around the track.
Create a hypothesis for how long it will take Cue to complete a lap on the track.
Code him to complete the lap and time how long it takes.
Use what you know about the relationship between distance, time and speed to determine how fast Cue travels in centimeters per second.
Extension: Create another track. DON'T MEASURE THE DISTANCE! Have Cue complete a lap on the track. Don't forget to time how long it takes. Using what you now know about how fast Cue travels, calculate the distance of your track.
Extension 2: Change the surface that Cue is travelling on. How would a track created in a grassy field change the results? Create a hypothesis and then test it out.
