Pupils needing extra support

Should use the Activity: How sieving works (support) and the sieving diagram from the Knowledge organiser to help them create an annotated diagram to explain how sieving separates different-sized solids; could use the clues under the tea towel to help them work out how the soil-gold mixture and iron-sand mixture could be separated.

Pupils working at greater depth

Should identify jobs which might involve sieving, such as farmer/harvester, chef, baker or food scientist; could be challenged to consider how salt and pepper could be separated (add water to dissolve the salt, filter out the pepper and then evaporate the water); could choose an extension activity relating to sieving from the Resource: Stretch and challenge: Mixtures and separation.
