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
