Dinosaurs Extinction

My son Edwin who is in P4 grade has to write simple English journal on a weekly basis.

The theme of a recent assignment is "How did dinosaurs disappear on Earth?"

Here is what he wrote.

"Dinosaurs ruled the Earth for over 65 million years. Then one day, there was a big space asteriod that hit the Earth. The whole Earth was on fire and all the dinosaurs on land died. Some dianosaurs living in water could still live. After the huge fire, it come the Ice Age. The dinosaurs in water also died. This did not end the Dinosaur Age.

There is a story saying that a dinosaur is living in a lake in italy. I think the story is true."
