Active learning ideas
Conservation of Biodiversity examines the ethical, economic, and ecological reasons for preserving species and habitats. Students analyze the current 'sixth mass extinction' and the primary anthropogenic drivers: habitat loss, overexploitation, pollution, and climate change. The unit covers the legal frameworks that protect biodiversity, including the UK's Wildlife and Countryside Act and international treaties like CITES and the IUCN Red List, as required by AQA 3.2.2.
Activity 01
Students take on roles as prosecutors, defense attorneys, and expert witnesses in a case involving the illegal trade of an endangered species. They must use evidence from CITES appendices to argue whether a violation occurred and what the appropriate penalty should be.
Why is biodiversity economically and ecologically valuable?
Activity 02
Stations feature different ecosystems (e.g., mangroves, peat bogs, tropical rainforests). Students rotate and identify the specific 'services' provided by each (e.g., flood defense, carbon sequestration) and the economic cost if these services were lost.
What are the main anthropogenic threats to species?
Activity 03
Students read a short article on the possibility of bringing back the woolly mammoth. They discuss in pairs whether resources should be spent on de-extinction or on protecting currently endangered species, then share their ethical stance with the class.
How effective are international conservation treaties?
A few notes on teaching this unit
Watch Out for These Misconceptions
Conservation is only about protecting cute or 'charismatic' animals.
Students often focus on 'flagship species' like tigers. A collaborative investigation into the role of 'keystone species' like fungi or insects helps them understand that biodiversity loss at any level can cause ecosystem collapse. Peer discussion helps shift the focus from aesthetics to ecological function.
Extinction is a natural process, so we shouldn't worry about it.
While background extinction is natural, the current rate is 100 to 1,000 times higher. Using a graphing activity to compare historical extinction rates with modern data helps students visualize the severity of the current crisis and the role of human activity.
Methods used in this brief
Conditions for Life on Earth
Review the historical conditions that allowed life to develop on Earth. Discuss how early life forms altered the environment to support greater biodiversity.
