the story
The Story
  • Juan Daniel loves to play fútbol
  • He lives near El Imposible in El Salvador
  • El Imposible is an endangered rainforest
  • During a soccer game, he finds a frog
  • The frog becomes a “lucky charm”
  • Challenge: keep frog healthy until Championship game
the challenge
The Challenge
  • Create an environment for the frog
  • Build a model membrane that allows water in
  • Keep water at constant drip
    • Water should not flood the frog
    • The frog should always be wet
the process
The Process
  • Poked hole in cup; created our sponge frog
  • Filled cup with cotton balls
  • Covered bottom of cup with plastic wrap
  • Poke holes in plastic wrap
  • Place frog in container
  • Place mesh over top of container
  • Pour water through the membrane device
problems we f aced
Problems We Faced
  • Not enough cotton balls (started with 0)
  • Holes were too big in plastic wrap
  • Pouring the water into a small hole
  • Getting the amount of water correct
    • Flowed too fast
    • Flowed too slow/got stuck in cup
improvements
Improvements
  • Filled cup completely with cotton balls
  • Used fine-point wire to poke holes
  • Used a pitcher with a spout to pour
future improvements
Future Improvements
  • Use wire mesh instead of cloth mesh
  • Find a way to cut a bigger hole in the cup
  • Try different materials that were not available
  • Use materials that weren’t suggested in book
  • Use more natural materials
    • Leaves
    • Grass
    • Rocks
engineering design process
Engineering Design Process
  • Ask: How do we keep the frog wet?
  • Imagine: Different materials
  • Plan: Created the design
  • Create: Built the membrane device
  • Improve: More cotton balls, future possibilities
