- Provide pupils with stimulus material,
eg pictures, video clips, to review their knowledge of reproduction in animals. Ask pupils to find out about the reproduction and development of certain animals,
eg fish, frogs, including information on fertilisation using texts, CD-ROMs and to make notes or summaries of their ideas.
- Discuss how eggs are fertilised externally in some animals,
eg fish, frogs, using video clips as illustrations and pointing out the numbers of eggs fertilised at one time. Ask pupils to suggest why this is.
