Teaching activities
Introduction
Recap that a material is what an object is made from; it doesn’t just
mean fabric.
Show the everyday items and ask what material each is made from. Make a list
of these materials on a large sheet of paper.
Activities
Select Characteristics of materials from the Science Clips website. Tell the
children you are going to test each material to find out it usually behaves.
First, go through the four tests to be carried out to ensure children
understand the words waterproof, flexible, strong, transparent. Drag the paper
into the tester. Ask different children to come out to carry out one of the
four tests. Ask them to predict what they think will happen, and then record
the result on the list made in the introduction. Are there any other obvious
properties they could add, e.g. paper is light. Repeat for the other materials.
Now click on the Workshop button. Show the children the blueprints for the
tyre, towel, saucepan, window, notebook and drinks bottle. In pairs, ask the
children to predict a good material to make each object from (from the list on
the board) and explain why, and suggest a material it could not be made from
and explain why. Ask them to write their choices on the worksheets.
Plenary
On the interactive whiteboard, use the Workshop to check the children’s
predictions. For each object, ask what are its functions and what properties
does it need? Which material has those properties? Which material would not be
a good choice? Why?

Extension
Umbrella Design Challenge. Ask children to design an umbrella to keep off the
rain. They must first brainstorm a list of possible materials they could make
it from. They should then go through the list and decide why it would not be
sensible to make an umbrella from some of the materials.

Suggested homework
Make four different designs for a cup, each made from a different material.
Two of the designs must work and two of them must not work. Children need to
explain why each of the cups will be a success or a failure.
