Week 3 - Teaching Science In Early Years

Question 1

What are materials?

Answer 1

Refers to all matter (solids, liquids and gasses)

Materials take up space and have mass

• an object is made up of materials
• a material is composed of substances
• a substance is composed of (contains) one or more elements (in combination)

Introduced in foundation

Question 2

Foundation year focuses:

Answer 2

Materials have observable properties

Post humanistic science and ecological sustainability

Question 3

Year 1 focus

Answer 3

Materials can be changed in a variety of ways

Question 4

Year 2 focus

Answer 4

Different materials can be combined for a particular purpose

Question 5

Year 4 focus

Answer 5

Properties and uses

Question 6

Natural materials

Answer 6

Natural materials produced by natural processes

Rocks, water and air are natural materials

Question 7

Processed materials

Answer 7

Processed or manufactured materials are also called synthetic materials

Question 8

Absorbency

Answer 8

Ability of material to take in liquids or gasses

Question 9

Flexibility

Answer 9

The ability of a material to be bent, twisted, stretched or noticed

Question 10

Strength

Answer 10

The ability of a material to resist or absorb forces

Question 11

Texture

Answer 11

The appearance and feel of materials - for example rough, smooth, sticky or grainy

Question 12

Transparency

Answer 12

The ability of a material to transmit light so that objects can be seen distinctly through the material

Question 13

Elasticity

Answer 13

Materials that have the property of recovering their shape after a force has been applied to them

Question 14

How can we classify objects

Answer 14

We can classify by type

What are it’s properties, what do we use it for, why is that good use for that

Question 15

Different types of materials:

Answer 15

Metals

Ceramics

Plastics

Fibres

Wood

Glass

Question 16

Physical science foundation focus

Answer 16

The way the object moves depends on a variety of factors including shapes and size so

Question 17

Physical sciences year 1 focus

Answer 17

Light and sound are produced by a range of sources and can be sensed

Question 18

What are sources of light

Answer 18

Sun

Fire

Hot things (incandescent light globe)

Light emitting doides

Flourescence

Phosphorescence

Question 19

Science behind sound energy

Answer 19

Sound is a type of energy made by vibrations

When an object vibrates it causes movement in air particles - the particles bump into the particles close to them which makes them vibrate more

Question 20

Physical sciences year 4 focus

Answer 20

A push or pull affects how an object moves or changes shape

Question 21

What are forces

Answer 21

A force is a push or pull

Force can affect objects in different ways

A force that causes a change in its motion by either speeding up or slowing down

A force can change the direction an object moves

A force may deform the shape of an object

Different types of objects can act on an object at any time - gravity and friction
