This practical activity gives students an opportunity to sample and identify life in a pond. The investigation looks at the effect of water pH on the organisms that live in the pond.

This practical activity allows students to model the growth of algae in ponds, within the school laboratory. By adjusting levels of phosphates and nitrates, students can see how a small increases in nutrients can lead to an increase in algae and summer algal blooms. This can be harmful to other organisms living in the pond. A presentation and short video clip introduces the topic and sets the scene for the investigation. Instructions and teacher guidance for carrying out the practical work are included.
