Objects and materials

Look around you. You can see lots of objects. An object is a thing, like a chair, a spoon or a bottle.
Every object is made from something. What an object is made from is its material. The chair is made from wood, so wood is its material. The bottle is made from plastic.
Some objects are made from more than one material. Scissors have metal blades and plastic handles.
Key ideas
- An object is a thing, like a chair or a spoon.
- A material is what an object is made from, like wood or plastic.
- Some objects are made from more than one material.
- To find the material, ask: What is it made from?

Watch out
Watch out: the object is the name of the thing, and the material is what it is made from. A chair is an object. Wood is the material. Do not say the object when someone asks for the material.
Exam tip
Grown-up tip. Point at things around the room and ask: “What is it made from?” Your child might say “wood” for a table. Praise every good guess, then check it together.
Try it at home
With a grown-up, find three things in the house. For each one, ask: What is it made from? Tell a grown-up your answers. Do not touch anything hot or sharp.
Working scientifically
What do you think you will find when you look at each thing closely? How could we find out what each one is made from?

Glass and water
Printable: Worksheet (PDF) · Answers (PDF) · Open this lesson on its own page
Glass is hard and see-through. We can see through a window or a clear jar. Glass is made by heating sand until it melts, then letting it cool.
Water is a liquid. It is see-through when it is clear. We find water in puddles, in rain and in drinks. Water has no shape of its own. It takes the shape of the container it is in.
Metal is not see-through. You cannot see through a tin.

Rock is hard, and it is found in the ground. A pebble is a small piece of rock. Pebbles on a beach are made of rock.
Clay is a soft, wet material from the ground. We can squash it and shape it. When clay is baked in a very hot oven, it becomes hard.
Brick is made from clay. Bricks are shaped and then baked until they are hard. A wall is made from many bricks.
