Look at these two things: a wooden spoon and a plastic spoon. Both do the same job. Where do you think each one came from?
Hands up: which one grew or was found in nature, and which one was made by people?
Some materials come straight from nature with only light change. We call those natural. Others are made or heavily changed by people. We call those manufactured.
Talk to your partner: is a cotton T-shirt natural, manufactured, or a bit of both? We will use the idea of a raw material (the starting stuff from nature) to help us decide.
In your group, sort every sample on your tray into two piles: natural or manufactured. Talk about each one before you place it. If you disagree, put it on a third pile called not sure and be ready to say why.
On the interactive, we will sort these materials: wood, wool, stone, cotton, paper, plastic, glass, steel, rubber, polyester fabric.
Polyester fabric means a fabric made by people, often from oil.
Together we will decide: is each one natural or manufactured? Use the question on screen to help you.
Your group gets one material sample and a research card. First look at the sample only: where do you think it started, and what do you think people did to it?
Then read the card to check and add detail. Decide together: is it natural or manufactured, what was the raw material, and which change people made was the most important? Be ready to tell the class in three short sentences, including your own choice about the most important change.
