Disappearing Dinosaurs Organiser’s Card About the activity This activity is designed to get children researching and debating the extinction of the dinosaurs. The children have been given a poem about dinosaurs, can they find out why they are now extinct?

Kit list • Access to the internet and/or books • Pens and paper What to do 1. Introduce the activity using the poem 2. Give out activity cards to the children. 3. Explain that they will be researching the extinction of the dinosaurs and planning a class debate. 4. Encourage children to discuss their ideas and how to carry out their investigations. Encourage speculation. Children may have their own ideas about dinosaur extinction. 5. Support children to conduct their investigation and make their own records of their results. Remind children that they need evidence to support a scientific theory. 6. Ask the children to present their findings to the rest of the group, they can be as creative in their presentation as they want.

Things to think about Scientists are still arguing about this question. They still don’t all agree. Children can consider whether it was a combination of factors that was bad luck for the dinosaurs. Prompt questions might include: Not every prehistoric creature died. Why did some creatures survive, including frogs, crocodiles and some mammals? Many scientists think birds are descended from dinosaurs. What evidence is there?
