Our topic this term is all about Antarctica. We will be finding out all about Antarctic explorers and the geography, climate and animals.
This week we found out that Antarctica is one of the seven continents of the world.
We also found out that millions of years ago our continents were not shaped the way they are today. As a matter of fact, they were not separate continents at all! Scientists now believe that the earth’s land masses were once all one giant land mass called Pangaea. Over the last 250 million years the continents have broken up and drifted to where they are today. Scientists call this Continental Drift.
They also believe that Antarctica was once a warm land roamed by dinosaurs!
This term we will be concentrating on non-fiction writing. Today, we wrote our own instructions for brushing our teeth. We spoke about the importance of making sure our instructions are written in the right order.
In the afternoon we learned about the structure of a tooth. We learned that the outer layer is called enamel, the layer under that is called dentine and the middle is very soft and called pulp. We made our own paper models of the layers of the tooth and labelled them.
Here is a good website for learning about the structure of a tooth.
