Challenges

And They're Off!

Challenge
This month is the 144th Kentucky Derby. The best horses will race 1.25 miles around the track at Churchill Downs. Who will help them guide the track? The jockey that rides the horses will do this. A jockey must be light in weight but still be able to control the horse. This a large factor in the competition and winning the race. So for this month, the challenge is going to be creating and designing a mock jockey for a mock horse! How can you make your jockey aerodynamic? How will the jockey stay on the horse? Where should the jockey sit? What will be the race conditions? Your challenge is to think about these questions and use all your given materials to build a jockey that will sit on top a matchbox car (your horse) and goes the fastest speed or longest distance.

Your jockey does have some criteria and constraints. Only the materials provided can be used in your design and ALL of them must be used. You should try to use the same matchbox car as everyone else in the class. The jockey must stay on the car for the entire race. You cannot change the car in any way. The race must be conducted as fair as possible.   

Materials
  • 1 matchbox car
  • 4 toothpicks
  • 2 index cards
  • 1 foot thread/string/yarn
  • 2 rubber bands
  • 5-feet string piece
  • 1 foot tape
  • stopwatch

​Hints and Tips for Success
  1. Allow students planning and discussion time by having them experiment with the items to see how flexible and movable they are. Students could test out cars to time them before their jockey is attached.
  2. After experimenting, allow student groups to plan their final design. Include as many ways to improve their jockey and race time as needed.
  3. For differentiation, adjust the amount of materials available, items needed to use, add any additional materials, take away materials, have students choose from a variety of cars, have the jockey need to look like a person. Adjustments could be made to make it more challenging or simpler.
  4. Create some sort of race track by using a wide piece of cardboard or other sturdy material set up like a ramp. This way multiple cars can be placed on the track at a time. Create a gate for the cars so that when lifted, all the cars start at the same exact time.
  5. Discuss if students would like to race to see which car and jockey is the fastest over a certain distance or travels the longest distance after leaving the ramp.
  6. Connect to science by discussing forces, air resistance, friction, speed, or variables.
  7. Connect to math by having students graph their times or measure the distance their cars and jockeys travel after each race.
  8. Connect to ELA by having students create a broadcast of the event as announcers of the race. Students can use a green screen app to broadcast and provide a photo finish for tight races.
