Project Outline
AskHow can your team get your rock to roll from one cone to the other?
ImagineLook back at pictures of the rocks rolling down the hill in the story.
  • You can’t move the rock in any way - it has to roll on its own.
  • You can only use materials given or purchased
Work with your team to draw out your plan (planning sheet included on last slide of Google Slides for this lesson) and create your shopping list.
CreateStudents will visit the “store” and create their slope and rock modifications according to their plans.
ImproveStudents will be constantly making improvements as their plans change with testing.
Closure / Student ReflectionsDiscuss as a group what was the hardest part of the challenge, what modifications worked the best, what would they purchase differently next time (if anything)
