Learning Objective: I can say how suitable a material is for different objects.
What do the words in bold mean?
Warm up: Have a look around your house and see if you can find an object that is made from the materials below.
Today we are going to be finding out more about the materials objects are made from. If we choose the wrong material to make an object from, they may not be suitable to use. We would not use fabric to make a knife and fork, they would bend and get soggy!
Look at the images below and see if you can identify any scientific vocabulary – do you know what it means?
Main activity: Using the items you have found, write sentences to describe them using the questions below. Remember to feel your objects to help you with this!
- Is it cold or warm to touch?
- Is it flexible?
- Is it hard or soft?
- Does it make a ringing sound when you tap it?
- Can it be squashed or stretched?
- Is it shiny or dull?
Challenge: Can you tell me why the material may be suitable for a particular object?
An example to help you get started: ‘Metal is cold, hard and shiny and makes a ringing sound when tapped. A knife and fork are made from metal because it is strong.’

Support: If you are finding this tricky, try finding one word to describe each material, using the word mat to help you.
