Material properties (Year 5)
Materials have different properties that make them useful for different jobs. Here are some properties that materials have.
Transparent or opaque
Transparent materials do let light through (you can see through them). Opaque materials do not let any light through (you cannot see through them).
Waterproof
Waterproof materials do not let water through and do not soak up water.
Strong
Strong materials are very difficult to break.
Flexible
Flexible materials are easy to bend.
Hard
Hard materials are difficult to scratch.
Magnetic
Magnetic materials are attracted to magnets.
Conductors
Some materials are good conductors of heat. This means heat can travel through them easily. Some materials are good conductors of electricity. This means electricity can travel through them easily.
Metals
Metals come from rocks called ores.They are strong, hard and shiny materials that can be hammered into different shapes without breaking.
Many metals are good conductors of heat and electricity.
Some metals are magnetic. Iron is the most magnetic metal. Steel is also magnetic because it is made of mostly iron.
Their properties make them useful for objects such as cutlery, saucepans, cars and coins.
Plastics
Plastics are materials that are not found naturally but are made from chemicals.
They are strong and waterproof, and can be made into any shape or colour. Many plastics can be made transparent.
They are not magnetic and do not conduct heat or electricity.
Plastics are used to make all sorts of things such as plastic bags, plastic bottles and toys.
Glass
Glass is made by melting sand.
It is normally transparent and can be made into many different shapes.
Thick glass can be strong, but thin glass will break very easily.
Glass is used for objects that need to be transparent such as windows and spectacles.
Wood
Wood comes from trees.
It is strong, flexible and long lasting.
Wood is used to make things such as furniture that need to be strong and last a long time.
Fabrics
Fabrics are made from thin fibres woven together.
Some fabrics, such as wool, cotton and silk, are natural (the
fibres come from living things).
Some fabrics, such as polyester and nylons are made from
synthetic fibres, which are made in factories, from chemicals.
Different fabrics have different properties. Fabrics can be
stretchy (a pair of tights),insulating (keep you warm, like a
woollen coat) or absorbent (a towel).
Fabrics are used to make clothes as they are flexible and comfortable, can be warm and do not wear out easily.

TECHNIQUE ANSWERING QUESTIONS - AIM / PURPOSE
Aim / Purpose of the investigation or things to find out.
Examples of questions
• What is the aim/purpose of the investigation above?
• State the purpose of the investigation.
• What is/ state the aim of the investigation/experiment/ fair test
• What is/ state the purpose of the investigation/ experiment/ fair test
• What are you going to find out.
The Sentence
To investigate the relationship between ..(what to change)..and ..(what to observe)….
To find out the effect of ….(what to change)…on/to ….(what to observe)….
TECHNIQUE ANSWERING QUESTIONS - INFERENCE
MAKING INFERENCE
· Using information from observations to make reasonable early conclusions.
· Making various possible interpretations from single observation.
· Using inferences as a tool to determine the appropriate additional observations.
· Testing the accuracy of inferences through additional observations.
· Give reason to an observation or making an earlier conclusion from what have been observed.
The Inferences
· Logical inference – any reason as long as it is logic.
· Comparing – any logical reason but the answer must be in a form of comparing.
· Controlled/exact – only one specific reason is accepted.
INGATAN UNTUK KITA SEBAGAI SEORANG GURU..
The Average Child
I don’t cause teachers trouble,
My grades have been OK,
I listen in my classes
And I’m in school everyday.
My teachers think I’m average,
My parents think so too.I wish I didn’t know that
`cause there’s lots I’d like to do.
I’d like to built a rocket,I have
A book that tells you how,
Or start a stamp collection-well
there’s no use in trying now.
`Cause since I found I’m average
I’m just smart enough you see,
To know there is nothing special
That I should expect of me.
I’m part of the majority,
That hump part of the bell
Who spends their life unnoticed
In an average kind of hell.
