Eutrophication is the growth of algae or other aquatic plants in water as a result of minerals in the water. These minerals often come from the breakdown of organic matter.

This brief resource gives five starter ideas for students and classes who want to investigate eutrophication. Options include using duckweed, algae and other suitable water plants.

The activities suggested would be suitable for investigations at GCSE, but could potentially be extended for post-16 work.
