Lesson summary

In this activity students design and conduct an experiment to compare the difference in plant growth between plants grown using tap water and greywater. Upon completion of the experiment, students are asked to record the changes to the plants with a camera and to produce data showing these changes.

Learning intentions:

Students will...

  • Identify how plants respond to grey water compared to fresh water.
  • Investigate, interpret and analyse data to create graphs.
  • Develop scientific explanations based on scientific knowledge, logic, and analysis.
  • Demonstrate the ability to work collaboratively to research and compile information on issues (extension/homework).
