What is matter?
Learn that everything around us that takes up space and has mass is matter, and that matter comes as solids, liquids and gases.
Lesson 2Solid materials
Explore solid materials such as wood, metal, plastic, glass and fabric and what makes each useful.
Lesson 3Liquid materials
Explore liquids such as water, milk, oil and juice and how they flow, take the shape of containers and can be measured.
Lesson 4Properties of solids
Describe and test properties of solids such as hardness, strength, flexibility, roughness and whether they float or sink.
Lesson 5Properties of liquids
Describe and test properties of liquids such as flowing, thickness, colour, mixing and whether they dissolve things.
Lesson 6Comparing solids and liquids
Compare solids and liquids by shape, flow, volume and what they do in containers.
Lesson 7Changing the shape of materials
Learn how some solid materials can be bent, stretched, squashed and twisted, and which changes can be reversed.
Lesson 8Melting
Learn that some solids melt and become liquids when they get warmer, and observe melting safely with ice.
Lesson 9Freezing
Learn that liquids become solids when they get cold enough, and observe freezing safely with water in a freezer.
Lesson 10Everyday uses of solids and liquids
Apply what we know about solids and liquids to everyday life: cooking, building, drinking, cleaning and choosing the right material.
