A fully-resourced lesson which looks at how decomposers are involved with the process of decay. The lesson includes an engaging and detailed lesson presentation (31 slides) and an associated differentiated worksheets.
The lesson begins by displaying the definitions for decomposers and detritivores and challenging students to use their bingo cards to see if they can work out the words which are being described. Students will learn how these two types of organisms work together to break down matter. Moving forwards, a worked example is used to guide students through how to calculate the rate of decay from a range of different data types. Students will be challenged to act like a travel agent for decomposers to come up with the different conditions that they require. Finally, they have to bring all of the new-found knowledge together to answer a range of summary questions. These questions are differentiated two ways so that differing abilities can access the work. There are regular progress checks throughout the lesson to allow the students to check on their understanding.
This lesson has been written for GCSE students (14 - 16 year olds in the UK)
