Teaching activities

Introduction
Write on the board or on a large sheet of paper a list of materials and a list of properties. Go through each material and ask which of the properties it has.

Activities
Tell the children you are going to think about which materials would be suitable for a making a notebook. What is a notebook used for? Which of the materials in our list can you write on? Make a list of these materials. Why are some of these materials unsuitable for a notebook even though you can write on them (e.g. too heavy, too bulky, the ink rubs off)? Which material is the most suitable? What properties does this material have that makes it the most suitable? Repeat this discussion for other everyday items, e.g. a towel, a saucepan, a window, an umbrella.

Divide the class into six groups. Give each group a collection of everyday items. In their groups, children fill in the Characteristics of materials worksheet recording the name of each item, its use, what it is made from, and why this is a good material to use.

Plenary
Why would these new inventions fail? A glass umbrella, a rubber cup, cardboard boots, a paper house, a metal shopping bag. In each case, you suggest one property of the material that makes it suitable for that purpose, and ask the children to explain why it would not be suitable.

Extension

Children look at objects made from two or more different materials, e.g. a saucepan, or a ring binder, and explain why different parts of the object have to be made from different materials.
