Recycling PBL

Problem Based Learning

Our PBL incorporated science and social studies aspects and was part of the background knowledge students needed in order to develop creative and innovative solutions.

  • City of the Future:  Humans use 70 gallons of water per day per person.  Water is a limited resource. What are ways that city planners can encourage reusing water and reducing water usage in future developments?
  • Improving Pipes:  Water expands when it freezes and exerts ten times the force required to break copper so pipes break easily in winter.  What are the effects of pipes breaking and how can it be prevented?
  • Improve Roads: What are the effects of damaged roads and how can it be prevented? Why put forth the effort to improve roads for our community?
  • Improve Recycling: How does the improvement of recycling centers impact communities?
