1

Materials are made up of tiny parts found in 3 different states, what are these stages

Solid
Liquid
Gas

2

We know that materials can change their state, when does this happen

When heat is added or removed

3

Where are metals found when mined

In different types of rocks

4

What are rocks that contain metal called

Ore

5

List the 8 properties of metals & explain each one
See photo

Hard - can't be bent or scratched eg. Train track
Shine - when polished it will shine but it can lose its shine or rust - will rust when oxygen combines with metal
Malleable - can be hammered into different shapes
Ductile - can be stretched into long thin strands
Strong - can hold the weight of heavy things
Melt - will melt at high temp
Conduct electricity - electricity passes easily through metal
Solid - will stay solid at room temp

6

How does rust occur and what color is it

Rust forms when iron is exposed to oxygen
Dark brown or red

7

What are the 6 properties of non metals
See photos

Are Soft
Are Dull
Are brittle
Do not conduct electricity
Do not conduct heat
Can be solid, liquid or gas at room temperature

8

What is conduction and give an example

The transfer of heat in metal
When one end of a piece of metal is heated, the other end gets hot

9

Magnets are metals that contain what

Iron, cobalt or nickel

10

What does it mean to be magnetic

It can attract certain metals

11

A magnetic filed can not be seen, what can you see

You can only see the effect of it

12

What is the only metal that is liquid at room temp and where can it be found

Mercury found in thermostats
