AQA GCSE Geography 2018 - What is an ecosystem?
Whole lesson, all resources included. Activities visibly differentiated on the slides. Clear learning journey.
This is a straightforward lesson aimed at a Y9 group with a little understanding of food webs / food chains.
The main aim of this lesson is to consolidate / teach students the main components of an ecosystem. The lesson includes a food web activity. By the end they should know the difference between a food chain and a food web, understand nutrient cycling and energy transfer, as well as develop an understanding of interdependence.
Activity: key terms activity (use the printout), display the key terms on the board. Students have to work out which term is which. Animated slide to help discuss this.
Content (teacher understanding required):
1. some key points to prompt discussion (students can write these depending on understanding).
2. animated slides to introduce energy transfer, food chains and food webs.
3. nutrient cycle diagram to explain and discuss
Activity: food web activity - students cut out each component, and place it on the food web using the descriptions. There is only one correct way for this to work so it's best to let students arrange them before gluing. There is also a key to colour code each component for producer, primary consumer, secondary consumer and decomposer.
Activity: there are some questions right at the end to test their understanding about change / balance in the food web.
