Cameron R.- Project Engineer - Responsible for helping members understand the team's task, leading team discussions, checking for safety at all times, and checking whether the team's task is complete. I would be good at this because I am on task and responsible.

Adam B.- Facilities Engineer - Responsible for collecting materials, directing model construction, directing cleanup, and storing materials. I am good at cleaning up and storing materials.

Cameron H.- Test Engineer - Responsible for recording and organizing data the Team Design Log. I am good at this because I am a good drawer and a good writer. I will keep them on task and record everything.

The Engineering Design Experience


Set Goals
  • What requirements must be met?


    Requirements:
    • Needs to travel at least three meters ( get to over 6 meters)
    • Needs to travel in a straight line
    • Can't be battery powered
    • has to be sturdy enough for kids to play with
    • has to be gravity powered
    • easy to repair
    • Can't be repaired by glue
    • has to be built by string, wheels and coragated plastic
  • What do you need to learn in order to build your design? What materials would work best and how to build everything and improve it.
  • How will you know if your toy design is successful? If it is fun to play with. It is able to travel 3 meters or more and in a straight line.

Build Knowledge
  • What are the basic parts to a Gravity Cruiser? We need a fulcrum, chaise, weight, lever, and rubber bands.
  • How do these parts work together? The gravity cruiser will use the lever and weight to make it go forward using gravity.
  • Build a model and then answer the following questions:
    • How does your model work? Are model works with a weight pulling with a lever arm, and wheels move it forward.
    • How could you make it work better? We could put something on the wheel to add more traction.


  • Change parts of the model, record observations, and discuss your results with other teams.
    • Amount of weights used (pennies)
    • Location of lever arm compared to the fulcrum
    • Location of lever arm compared to the support beams (move up or down)
    • Size of wheels
    • Length of lever arm
    • Length of the string
    • Legth or size of the support beams
    • Wheel location
    • Length of wheel axle
  • Make predictions on what parts allow your model to be a quality toy that meets all requirements

Design
  • What ideas do you have for your design? We will test out Mrs.Brown design and then making a design what is better.
  • What will make your design stand out among all the other teams? We will make it go far.

Build & Test
  • Build and test your design that meets the performance criteria
  • Redesign as time allows to create the optimal toy (Keep in mind the appearance of your cruiser)

Present
  • Show and describe your work to an audience
