Population size and competition - complete lesson AS/A2

A full differentiated lesson based on the OCR-A SOW. This lesson was used by myself for an A2 class but the content is simple enough for AS. The lesson covers sigmoidal population growth curves, abiotic and biotic limiting factors, migration and density independent factors. Student understanding is then checked through the use of a differentiated question grid tailored to the lessons LO. Students are then introduced to intra and interspecific competition using examples. The red/grey squirrel example is discussed. Students then apply their learning to 2 exam style questions. The plenary is based upon the students reflecting upon their progress against the learning objectives. All answers are included within the slides facilitating self/peer marking, timers are included to promote pace.
