Transparent and opaque materials: review

I can name transparent and opaque materials and talk about how they are useful.

Lesson details

Key learning points

  1. The results of an investigation can tell us which materials are transparent and opaque.
  2. Materials can be sorted into transparent and opaque.
  3. Scientists think about how transparent and opaque materials can be useful to us.

Common misconception

In comparing the extent of a given property in two materials children may rely purely on observation rather than on active testing.

Ensure children have been able to test materials and generate a set of results.

Keywords

  • Material - A material is what an object is made from. An object can be made from more than one material.

  • Transparent - Transparent materials are completely see-through.

  • Opaque - Light cannot pass through objects that are opaque.

  • Results - The result of a test or enquiry is what happened or what was found out.

Ensure that children have had opportunity to test materials prior to this lesson (see lesson 8 of this unit) so that they have developed an understanding of materials that are transparent and opaque.
