This lesson is designed for the Activate KS3 Science Course, specifically Year 7 B1.3 Module on ‘Reproduction’.

The lesson begins with an introduction to the definition for ‘gametes’, students will learn the role of the gametes in fertilisation and the specific structural features that sperm and egg cells possess which help them to carry out their function. Once students have learned about this, they will then complete on gametes structure to function.
Once this task has been completed, students can self-assess their work using the mark scheme provided.
 
Students are now introduced to the idea of fertilisation, a description of the process is provided, which students could take notes on in their book. This is followed by a task whereby students are given three terms - fertilisation, sperm cell and egg cell - using a bank of key words they will be required to write a definition for each.
 
Next, students are shown a labelled diagram depicting sexual intercourse as well as an explanation of the process. The explanation should be read through as a class, answering any questions where necessary, before students are asked to complete a ‘progress check’ of questions on sexual intercourse. This work can then be self-assessed using the mark scheme provided.
 
Lastly, students are shown a video of the journey a sperm cell has to make to reach an egg cell. Whilst watching the video, students will need to fill in the blanks on a cartoon strip depicting these events.
 
Again, the mark scheme for this task is included in the PowerPoint for students to either self-assess or peer-assess their work.
 
The plenary task is a 3-3-1 reduction, students need to write down 3 facts and 3 key words from the lesson today, as well as 1 question to test their peers knowledge of what was learned.
