  1. Jump, Don’t Bump! Bungee Jumping

  2. Bell Ringer Adventures, Inc. has hired your student engineering team to design a thrilling event for their new amusement park. Your team has decided to create an exciting bungee jump. To do this you must design bungee cords that will be safe and give people a thrilling jump. On a notecard list some things you need to know and do to successfully complete this challenge.

  3. Engineering Design Process

  4. Define the Problem What will our bungee cord need to be able to do? Take a look at a bungee jump

  5. Your bungee cord must be safe and give people a thrilling jump. What do you think are the most important things in bungee jumping safety? Think about this …

  6. Your Engineering Challenge Design a bungee cord prototype that will allow objects of different weights to fall from a height of 75cm. without hitting the floor and spring back several times.

  7. Engineering Design Process

  8. Make a rubber band bungee cord Connect one rubber band to another with a slip knot. Watch this quick video of how to do this. Keep fastening rubber bands together until you get a bungee cord the length you want it.

  9. Criteria and Constraints • Criteria: The cord must allow the object to: • Fall almost 75 cm • Come close to floor without touching it • Bounce (spring back) more than once • Constraints: Teams must: • Use only materials provided • Use only one size of rubber band • The bungee cord must not break

  10. Test Your Bungee Cord • Construct a bungee cord with the number of rubber bands you think you will need. • Devise a way to attach the bungee cord to the bottle. Use this method for both bottles. • Stand the meter stick up (or tape it to the end of the table) and hold the end of the bungee cord at the 0 cm. mark. • Drop the bottle from the 0 cm point. A team member at floor level should call out the mark the bottle reaches on this drop.

  12. Bell Ringer 1. What is the problem we must solve? 2. What steps of the EDP have we already done? 3. What steps do you think we will do today? 4. Do you think we must always follow these steps in the order they are listed?

  13. Consider this . . . • Which bungee cords had the longest length drop without hitting the floor? • Which bungee cords had the greatest number of bounce backs? • Did any bungee cords have both the longest drop and the greatest number of bounce backs? • Which bungee cords used the most rubber bands? • Whyconsider the number of rubber bands? • What does your team think is most important to consider when designing your bungee cords?
