Engineering a

Challenge

• Design and build a cranking elevator to lift items to the top of a 1 meter height.

Challenge continued

• Your lifting device must make use of a turning handle that will wind the elevator system to the top while carrying a small container of assorted candy, load a small pumpkin or gourd and then release it and carry it safely back to the ground without spilling or causing the cargo harm.

Materials

• paper clips
• cardboard or cardstock
• craft sticks
• dowel rods
• pipe cleaners
• rubber bands
• straws
• bucket
• string
• tape

Constraints

• 4-5 jumbo paper clips
• cardboard as needed
• 8 craft sticks
• 3 feet of string
• roll of masking tape
• 1 six inch dowel stick
• 1 pipe cleaner
• 4 rubber bands
• 4 straws

The pumpkin and candy will be provided. You can make your own container to carry the candy or use a small cup.

Final instructions

• Because the lifting device will be carrying two loads - candy then a pumpkin, the candy holder will need a handle. The second load will need a platform built on which the pumpkin will sit as it is raised.
• The elevator may be attached to the tabletop during lifting
