Are they strong? Are they flexible?
Are they warm or soft to the touch?
Can you see through them?
Talk about why each material has been chosen for the job.
Strong, flexible and soft are different properties of materials.
Activity 4.2 (Rough and soft fabrics)
You will need: four or five different fabrics - a magnifying glass
Some fabrics are soft, some are rough, some are smooth.
Which fabric do you think will be the smoothest?
Look at the fabrics with a magnifying glass. Feel them.
Put them in order from the smoothest to the roughest.
Were you right?
Have your friends put the fabrics in the same order?
A fabric has many small threads called fibres. The way in which these fibres are woven together makes the fabric feel rough or smooth.
