Bugs lessons

Class-based lesson and field trip for new entrants through to year 8 pupils

Discover during the class lesson:

Your pupils will discover what the freshwater bugs (macroinvertebrates) that live in our waterways look like. They will find out how they can determine the water quality in the waterway depending on which bugs are found.

Investigate during the field trip:

If the waterway is shallow and easy to access, your pupils will scoop up bugs and empty them into ice-cream containers. If the waterway is not easy to access, the bugs will be scooped up by the adult supervisors.

The pupils will examine the bugs using magnifying glasses. They will identify the bugs and record them on the bug sheet with the assistance of the adult helpers.
