Week 3 - Teaching Science In Early Years Flashcards
What are materials?
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
Foundation year focuses:
Materials have observable properties
Post humanistic science and ecological sustainability
Year 1 focus
Materials can be changed in a variety of ways
Year 2 focus
Different materials can be combined for a particular purpose
Year 4 focus
Properties and uses
Natural materials
Natural materials produced by natural processes
Rocks, water and air are natural materials
Processed materials
Processed or manufactured materials are also called synthetic materials
Absorbency
Ability of material to take in liquids or gasses
Flexibility
The ability of a material to be bent, twisted, stretched or noticed
Strength
The ability of a material to resist or absorb forces
Texture
The appearance and feel of materials - for example rough, smooth, sticky or grainy
Transparency
The ability of a material to transmit light so that objects can be seen distinctly through the material
Elasticity
Materials that have the property of recovering their shape after a force has been applied to them
How can we classify objects
We can classify by type
What are it’s properties, what do we use it for, why is that good use for that
Different types of materials:
Metals
Ceramics
Plastics
Fibres
Wood
Glass
Physical science foundation focus
The way the object moves depends on a variety of factors including shapes and size so
Physical sciences year 1 focus
Light and sound are produced by a range of sources and can be sensed
What are sources of light
Sun
Fire
Hot things (incandescent light globe)
Light emitting doides
Flourescence
Phosphorescence
Science behind sound energy
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
Physical sciences year 4 focus
A push or pull affects how an object moves or changes shape
What are forces
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
