Science Y1 – Managing materials – week 3
FOCUS ON METAL

Truth to Teach (Source)

God has stored ores in the ground and over time has enabled man to extract and use the
metals contained in them. He is Jehovah Jireh, God who provides.

Job 28:10 ‘Man tunnels through the rock; his eyes see all its treasures.’

Way to Work (Means)

1. Have a display of a variety of metals and metal objects to hand.
We realised last week that there are different types of wood. Are metals all the
same? Ask for the names of as many metals as they know and list these on the
board. Working from the answers given, identify and label certain metals. e.g. the

‘gold’ metals are not necessarily gold - brass.

Copper is easily recognisable by its colour.
Copper can be ‘pulled’ until it is very thin - wire - allowing electricity to
pass along it. (All metals do.)
Are all metals strong? Aluminium can be beaten until thin. Difference in
weight between aluminium and steel

Show a rusty object - what has happened?
Show a tarnished object - has this rusted? Ask the children to polish it.

2. We know wood comes from trees. Where do metals come from?
God has hidden metal underground in rocks. It is like ‘treasure in a rock’. Rocks with
a lot of metal in them are called ores. Iron comes from iron ore.
Extraction: involves heating - liquid ore - metal is heavier - drained off. God has
helped people work out how to get the metal out of the rock.

Gold is different - found in the ground as a pure metal.
Gold and silver - precious metals.

3. People often mix metals together. Steel is a mixture of a metal – like baking a
cake. It is stronger than iron. Iron and steel are often used to make large
bridges, cranes and ships.
You can always tell if something is made of iron or steel. How?
It will be attracted to a magnet. Is anything made of iron or steel in this room?

4. Worksheet.

5. Gather and compare what happens when spoons of different materials are placed in

boiling water. (metal, plastic, wooden)
Why do saucepans often have plastic or wooden handles?
Inventors and craftsmen need to know about different types of materials.
