This lesson is designed for the NEW AQA Trilogy Biology GCSE, particularly the 'Homeostasis' 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 This lesson begins with a think > pair > share task asking pupils to consider the different ways in which males, females or both could potentially find difficulty in conceiving a baby. Images are shown in order to prompt students to think about the anatomy of the male and female reproductive system. Answers will then be provided, pupils can check their ideas against those shown on the PowerPoint slide and red-pen their work. The next task is a fill-in-the-blank task on the role of FSH and LH during fertility treatments, pupils will need to consider the job of these two hormones in a healthy woman (covered during the menstrual cycle lesson) and then summarise how these hormones are used in fertility drugs. This work can be assessed using the answers provided once complete. The next part of the lesson focuses on how in vitro fertilisation works, pupils will be shown diagrams and descriptions of the stages involved with this process. Extra challenge questions are provided at the bottom of the worksheet should some students complete their work quickly. Pupils will then need to complete a worksheet o summarise these steps, once completed this work can be assessed using the mark schemes provided. Finally, students will need to consider the advantages and disadvantages of IVF. They will be given some information, one between two, they will need to use this information to summarise the pro's and con's of IVF. For the last task pupils will be given opinion cards in groups, they should read out the opinion cards and discuss which one's they agree with and why. They should then write a conclusion of their own opinions on IVF in their books, using as many valid scientific points as possible. The plenary task is for pupils to write a twitter message about what they have learnt that lesson. All resources are included at the end of the presentation.
