Year 5: Separation techniques and food preservation

The Year 5 Kitchen classes commenced Term 2 learning about the many different ways that mixtures can be separated in the kitchen and how these techniques can prevent food waste.

Separation techniques used in the Kitchen may involve physical separation (eg. Filtration using a strainer), or it can involve chemical separation using a catalyst, such as vinegar or lemon juice. Students learnt that catalysts are used to speed up a chemical reaction and the separation of a mixture.

For centuries, people have used such separation techniques to create cheese as a way of preserving and storing food for later. As you can see below, the Year 5 students thoroughly enjoyed making their own Homemade Ricotta cheese and were very surprised how quick and easy it was!
