Water quality lessons

Class-based lesson and field trip for pupils in years 5 to 8

Discover during the class-based lesson:

Depending on the duration of the class, your pupils will have the opportunity to learn about:

  • the water cycle
  • how streams become polluted
  • how to identify freshwater bugs (macroinvertebrate)


Your pupils will also have the opportunity to practice testing the turbidity, pH and nitrate levels present in water samples.

Investigate during the field trip:

Your pupils will have the chance to put theory to the test. They will measure and record the turbidity, pH and nitrate levels of their local waterway and identify the bugs living there. Once they return to the classroom, they can examine their results and make an assessment on the quality of the water in their waterway.
