Intro to ecosystems - complete lesson (A2)

A full lesson introducing the topic of ecosystems. The lesson is based on the OCR-A SOW but can be used for others. The lesson introduces key words relating to ecosystems through video, and has a simple match up activity to allow for AFL. Students then learn about biotic and abiotic factors making use of examples. They then participate in an activity where they must correctly categorise factors as biotic and abiotic from the board. A past exam question is included as a 'stretch question' to reinforce learning at this point. Students are then introduced to food chains, webs and trophic levels prior to a final 'question grid challenge' with differentiated questions based on the learning objective of the lesson. The plenary is based on reflective writing, where students gauge their progress towards the lessons learning objectives, and how they can improve.
