Materials List: Engineering a Solution to Study Soil Mechanics

Each student needs:

Each group needs:

  • a plant in a transparent container
    • note: it should be far enough into the growth phase that roots can be clearly observed
  • container with only soil
  • mist spray bottles with measurements on the bottle
  • clear ruler (in cm)

To share with the entire class:

  • weights to act as a force on top of the tested soil
    • metric weight set (two sets recommended; available at Learning Resources or other online sources)
  • PocketLab with pressure sensor (PocketLab and pressure sensor available online; activity can be modified to use a different tactile pressure sensor)
  • fertilizer (for one group)
  • herbicide (for one group)
