Separating Mixtures: Filtering and Sieving — Interactive Lesson (Ages 9–10)

Can your pupils choose the right way to separate a mixture? This 17-slide interactive lesson teaches separating mixtures using filtering and sieving, and links each method to solubility.

Learning About Separating Mixtures in Year 5 Science

Pupils start by identifying which substances are soluble and which are insoluble in water, then apply that idea to real mixtures. They learn how sieving, filtering and evaporating work, decide which method suits each mixture, and answer questions such as how sand can be separated from water and why sugar and water cannot be separated by filtering because the sugar dissolves.

What’s Included

• 17-slide interactive lesson with four clear learning objectives
• Soluble and insoluble substances, and the idea of solubility
• Filtering, sieving and evaporating as separation methods
• Questions on the equipment needed for filtering, such as a funnel and filter paper
• Self-marking questions with instant feedback

Key Benefits for Students

• Links separation methods to whether a substance dissolves
• Helps pupils choose the right method for each mixture
• Uses familiar examples such as sand, water, salt and sugar
