Watch children and talk to them as they carry out their observations and sorting. Can children identify the difference between translucent, transparent and opaque materials?
Can children use a magnifier to make simple observations about an object?
Are the children able to recognise properties such as hardness, strength and flexibility?
Can children make comparisons between materials?
Quizzes available in pupil zone.

The Science Behind the Science
Transparent materials can be seen straight through, like glass. Translucent materials can be seen through, but not as clearly as glass, such as a green plastic bottle. Opaque materials cannot be seen through at all, like wood.
Opaque materials can cast the strongest shadows as they let the least light through them. A perfectly transparent material will not cast any shadow because it allows all of the light travel through it.
To describe the simple physical properties of a variety of everyday materials.
The study of the properties, behaviours and uses of materials, both natural and human-made; the origins of human-made materials and how they are manipulated to suit a purpose.
Grouping and classifying.
Identifying and classifying; Observing closely using simple equipment.
