Ecosystems & sustainability
Ecosystems & sustainability helps us explain how the world works. Scientists study it by asking questions, making predictions and testing them — and in this lesson you will do the same.
The most important part of ecosystems & sustainability is not memorising facts but understanding the ideas behind them. Once you understand the "why", the facts become much easier to remember and use.
You can see ecosystems & sustainability at work all across Canada — in nature, in technology and in your own home. By the end of this lesson you will be able to explain ecosystems & sustainability and give a real Canadian example.
