Properties of Materials

Strong, weak, hard and soft are properties of materials.

Different Properties

Flexible, rigid, shiny and dull are different properties.

Rough and Smooth Fabrics

Some fabrics are rough. Some fabrics are smooth.

Feeling the Threads

Look at some fabrics and feel the threads the fabrics are made from.

Bigger Threads

Rough fabrics have bigger threads.

Think Like a Scientist

Rough and smooth fabrics

You will need: four different fabrics, a magnifying glass.

What to do:

Observe some different fabrics.
Which are rough? Which are smooth?
Look closely with a magnifying glass.
Feel the fabrics.
Sort the fabrics. Put them in order from rough to smooth.

How am I doing?

Have your friends put the fabrics in the same order?

Thinking About the Best Material

Which material is the best? Is it water?

WHAT WE LEARNED

Today we learned that materials have different properties, such as hard, soft, rough, smooth, shiny, or dull. We practised observing and touching materials to find out what they are like. Great work exploring materials like a scientist!
