Anticipated Learner Outcomes

  • engineering design process
  • teamwork in the design process
  • making and testing predictions
  • product design challenges

Lesson Activities

Student teams will design a candy bag, and predict the volume and strength of their design. Students then build a model of their design, redesign it, build an improved bag, retest using weight, discuss findings, and share results.
