Interdependence and Adaptation KS4

This is a series of resources which can be used to teach the topic "Interdependence and Adaptation" at KS4.  It fits best with the AQA Science A specification but could easily be adapted for other specifications.

It is envisaged that lessons would run in the following sequence:

1. Food chains and webs, predators and prey (revision of a KS3 topic) using the article "Food Webs Uncoupled".  This could be followed by one or more of the activities/investigations from "Competition and Predation".  The factors affecting the size of a population can be addressed at this point.  The article "Predators, Prey and Populations" could be used as an extension task.

2. Adaptations and competition.  The adaptations of different plants and animals enable them to be effective competitors.  The "Adaptations video" provides a good stating point for pupils to find out about some adaptations of organisms.  Some background information about the adaptations of whales, dolphins and seals is given in the article "Diving Deep", whilst "How plants grow" has an extended activity on the adaptations of plants.  Alternatively, students could be asked to research different organisms to produce a poster or a presentation on their adaptations to their environments.

3. Extremophiles.  Students need to be able to explain how some organisms are adapted to live in the most extreme conditions.  They could be asked to use the three website in the list to research examples of these organisms.

4. Indicator species of pollution.  Use the final two resources on the list to investigate how different species of lichens and invertebrates can be used to monitor pollution in the air and rivers respectively.
