Students learn about the super food that is the potato and how just a little bit of water can lead to a whole new plant.


  • Pierce the middle of the potato with toothpicks and suspend it over the plastic pop bottle jar.
  • Fill the jar almost to the top with lukewarm water and set in a bright windowsill.
  • Have students create a potato journal with several pages for illustrations and writing observations.
