Activity: Conveyor Engineering

Trafficjam

Lesson courtesy of TryEngineering.org

Summary

In this activity, teams of students in grades 3 to 12 explore how engineers work to solve such societal problems as moving goods, materials, and people by developing a conveyor system out of everyday materials than can transport  pieces of candy 4 feet, including a 90-degree turn. Teams evaluate their results and reflect on them as a class.

Grade level: 3 – 12

Time: Two or three 45-minute sessions

Materials   conveyor belt schematic

For each team:

  • Candy or similar sized items, such as washers or pennies
  • Tubes (can be paper towel rolls, toilet paper rolls, or PVC)
  • Piping or other similar materials – or even rows of soda bottles or pencils
  • Rubber bands
  • Ball bearings
  • Balls
  • Fabric sheets
  • String
  • Gears
  • Handles
  • Paper cups   luggage cartoon conveyor
  • Straws
  • Paper towels
  • Paper clips
  • Tape
  • Soda bottle
  • Glue
  • String
  • Foil
  • Plastic wrap
  • Pens/Pencils
  • Paper
  • Hose or tubes
  • Crayons and other items available in the classroom

Procedure    suitcase cartoon

  • 1. Show students the student reference sheets. (Page 4 – 7 of the pdf.) These may be read in class or
    provided as reading material for the prior night’s homework.
  • 2. To introduce the lesson, consider asking the students if they have been to anairport and wondered how their luggage was sorted or delivered. Ask them to think about any “moving sidewalks” they have traveled on (airports, malls, other large buildings).
  • 3. Working in teams of 3 to 4, students should research how conveyor belt systems operate and then brainstorm ideas for designing one.
  • 4. Teams then consider available materials and develop a detailed drawing showing
    their conveyor system including a list of materials they will need to build it.
  • 5. Have students build and test their conveyor system, also observing the systems developed and tested by other student teams.
  • 6. Teams reflect on the challenge, and present their experiences to the class.

Extensions

  • Have advanced or older students power their conveyor systems with motors or gear systems.
  • Have students write an essay or a paragraph about three existing and one imagined application of a conveyor belt system.
