For Science Week, Year 3 learned about the various theories which possibly explain the extinction of dinosaurs. We did some research then discussed which theories we felt were most likely to have been correct. The children then made their own posters explaining their theory of the extinction of dinosaurs. We also looked at how long ago dinosaurs were around. Did you know that dinosaurs roamed the globe for about 165 million years, compared to humans having only been around for about 300,000 years?
