Mixtures

Matter can be classified as a Pure Substance or as a Mixture. How do we decide?

Our sciPad (p27) had some everyday substances we had to classify. How did we make our decisions?

The generalisation has to be completed for homework. We were give some hints, such as: salt being made of two substances, yet not being a mixture; there being different types of dirt...but they are still called dirt!

We also have to complete p28 in our sciPad for homework (by Friday).
