This lesson is designed for the NEW AQA Trilogy Chemistry GCSE, particularly the ‘Organic Chemistry’ SoW.
Firstly, pupils will need to complete a ‘True or False’ activity on carbohydrates, they will then be shown how polysaccharides are made from monosaccharides via a condensation reaction, as an example of a natural polymer. Pupils will also be provided with information on the structure of starch and glycogen ad how this relates to the function of these two polymers.
Another example of a natural polymer are polypeptides/proteins which are made up of the monomers - amino acids. Again, pupils will be shown how a condensation reaction occurs to link together many amino acids molecules in a long polypeptide chain.
Pupils will now complete a ‘Quick Check’ task to test their knowledge of what they learned so far this lesson, the answers to the questions will be provided in the PowerPoint for students to assess their own work.
The next part of the lesson will focus on DNA as a natural polymer. Firstly, pupils will need to order the structures given in order of size - DNA, gene, chromosome, nucleus, cell. Next, pupils will watch a video on the structure and function of DNA and will need to answer a set of questions. This work can then be self-assessed using the answers provided in the PowerPoint. A diagram is then shown highlighting some of the key structural features of a double-helix DNA molecule, which pupils need to know and remember.
The final task is a ‘Quick Check’ activity on the structure & function of DNA, students will need to answer the questions in their books and then peer or self-assess their work using the mark scheme provided.
The plenary task is for pupils to write three quiz questions for pupils to test their peers knowledge of the topic learned in the lesson today.

This resource is excellent, just what I need for GHL, however I can't access the video and having tried to copy the address can't work out what are capital I 's or lowercase l's so not sure I have put this in correctly. Hoping that you can send out the link. Many thanks.
Great lesson! Thank you so much, saved me a lot of time on a Friday morning!! Great structure to the lesson.
