NEW AQA GCSE Trilogy (2016) Biology - Rates of decomposition

This lesson is designed for the NEW AQA Trilogy Biology GCSE, particularly the ‘Ecology’ SoW.

For more lessons designed to meet specification points for the NEW AQA Trilogy specifications for Biology, Chemistry and Physics please see my shop: https://www.tes.com/teaching-resources/shop/SWiftScience

Pupils are firstly given some information, in pairs, on how temperature can affect the rate of decay. They are asked to read through the information and complete a set of questions. Once this task is complete pupils can self-assess their work using the answers provided.

The next task is for pupils to think > pair > share ideas about how you could stop or delay the decay process with food. Some images are provided on the PowerPoint slide as a prompt to help students, they can also use the information from the first task to help them come up with ideas. Once pupils have been given time to write their ideas down you can discuss as a group and then reveal the 5 main ways in which foods can be preserved.

Pupils will then be given a set of information about each of these preservation methods, they need to use this information plus the information from the first task they completed to explain how each of the methods helps to prevent or delay the decay process. Pupils can then self or peer assess their work once complete.

For the next task pupils are asked to use information posters places around the room or on their tables to answer a set of questions about decay & recycling. Once pupils have completed these questions they will need to assess their work using the answers provided.

The very last task is an exam question that pupils can either complete in silence at the back of their books - higher ability - or perhaps use the work they have completed this lesson if they are lower ability.

The plenary task is for students to write three sentences to summarise what they have learnt this lesson.
