It is infeasible to measure all of the pollutants that may exist in a waterway. Instead, scientists monitor ‘indicators’ such as water bugs to measure the condition of waterways.
In this module, students will:
- understand the meaning of tolerant and sensitive water bugs
- observe water bugs from their local waterway
- identify water bugs using a Waterbug Identification Guide, as an indicator of the quality of the water from which the bugs were collected
