Interdependence
With current estimates suggesting that a third of the world’s amphibians, a quarter of all mammals and one in eight birds are now endangered, human impact on ecosystems around the planet is becoming more and more apparent. These resources explore interdependence - from food webs to adaptation, from loss of habitat to the competing priorities involved in species conservation.

Video
Life in the Water *suitable for home teaching*
As a starter, introduce the idea of food webs with this short video. Phytoplankton and zooplankton have a crucial place in the Arctic food chain, which is highly sensitive to change.
Having watched the video, there are two activities for students:
Activity A - Food chains uses the Arctic food chains to show why a pyramid of biomass is more useful than a pyramid of numbers.
Activity B - Arctic food web develops ideas about food webs and encourages students to think about how species are adaptated depending on their food source. .
Future Morph: Chief Scientific Officer (Raptor Biologist)
To end the lesson, show students what it would be like to work with birds of prey with this engaging video, highlighting career opportunities for those with biology qualifications. Part of the biologist’s work at the Hawk Conservation Park is to set up nest boxes for British birds of prey, which includes monitoring prey abundance using the capture-mark-recapture method.
This is also a good lead into the next lesson on adaptation.
Marine Biologist
Lead into the next resource by showing this video which highlights the work of a marine biologist.
Presentation
Adaptations for Movement (Age 11 to 14)
There is an excellent presentation in these resources which looks at the definition of adaptation, why animals need adaptations to move successfully in their natural habitat and the difference between a specialist and a generalist species. Students can then complete the worksheet to assess their understanding of the ideas by describing the adaptations of a range of animals.
Adaptation: Design a Species Activity
Using the marine environment as an example, students learn about how different animal species are adapted physically or behaviourally to survive in this habitat.
Students can then research an allocated habitat, taking into account local predator or prey species, and design a new species of animal or plant to suit the conditions. They then present this species to the class.
Article
Life in the Balance?
A Catalyst article about Earth’s biodiversity much of which appears to be teetering on the brink of a man-made extinction crisis. Scientists have suggested that, unless urgent action is taken now, many species will disappear in the next 50 years. This article looks at some of the issues involved.
Again, useful as part of a display on biodiversity, or in a research pack.
Game
Endangered Species Bingo (Age 11 to 14)
What happens to a highly adapted species if their ecosystem changes? This engaging lesson introduces students to the issues around endangered species.
Firstly the visually engaging presentation describes what is meant by an endangered species. Then, using the ARKive website, students explore endangered species around the world, each species’ conservation status, and the various factors leading to that species endangered status by filling in the Conservation Definitions worksheets provided.
As a plenary, concepts and definitions can be reinforced by playing Endangered Species Bingo, which incorporates all the species the students will have researched online during the main activity.
Information sheet
Biodiversity *suitable for home teaching*
This colourful leaflet looks at what biodiversity is and why it matters. It also explains how human activities threaten the natural environment, endangering species and habitats and what we are doing about the problem. It would be good as part of a display on biodiversity, or in a research pack if you do not have access to the internet for the previous activities.
Activity sheet
Biodiversity Hospital
With this Arkive resource, students can learn more about the importance of biodiversity and species conservation. In a finely balanced ecosystem there are competing priorities when considering the conservation of an endangered species and difficult decisions need to be made.

Team Wild
This online game for students highlights some of the work being done by scientists and conservationists around the world to protect threatened species and habitats. Supported by four topic pages with links to related teaching resources, the game is a fun way to end the topic and let students find about some less well known career choices.
