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. 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.
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.
Free posters from the Linnean Society to download (or order printed copies) on biodiversity, conservation, classification and evolution.
Activity to measure diversity within a habitat.
This is not a balanced arguement of intensive versus traditional farming.

A detailed description of parasitism and mutualism, including detailed examples.
A one page summary of the carbon cycle including a slide show.
A one page summary of the nitrogen cycle including a slide show.
Linekd pages describe several of the more common ecological sampling methods, why they are used and the general reasons for sampling.
A description of why some animals are endangered or extinct and how they can be helped, with a focus on whales and fish.
Linked pages describe common examples of air and water pollution, their causes and their effects.
