MiniSASS in P3 & 4

14th Jun 2018

We have been continuing our 'Water Explorer' journey.

Today we took on a new challenge: Is your water source polluted?

We thought of ways our fresh water sources can be polluted and saw some evidence of this down by the river.

We discussed how the health and quality of the water can be measured. So we thought about looking at the creatures that live in the water. Using a Dichotomous Key we tried to identify our findings.

We found a little eel, hairworms, midge larva, beetle larvae caddis fly larvae, mayflies and we think a tiny shrimp.

From our findings the river is in fair condition but we really needed some deeper water.
