The properties of materials

Hi kids!

We are learning new and interesting facts  about materials and their properties.

Let’s revise them!

 

 

Materials properties

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.

Absorbent

Absorbent materials soak up water and let water pass through them.

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.

Insulators

Some materials are insulators of heat. This means they do not allow heat to travel through them very easily. Some materials are insulators of electricity. This means that electricity cannot travel through them.

WHAT ARE THINGS MADE OF?

Do you dare to test your knowledge?

What are things made of?

There are many different kinds of materials in the world. Try this activity to learn about the materials used  to make the things that we need every day. We already know that our pyjamas can be  made of wool, cotton or polyester …but balloons or car tyres can’t be made of cotton, silk or wood.

Let’s investigate!

THE THREE R’S

Hi kids!

You know we are learning a lot about materials and their uses. Plastic,  glass,  paper, metal, wool, wood, cotton… Many of them can be recycled. It is necessary to understand that every time you throw rubbish away you can make a big difference if you do it in the recycling bins.

Remember this colour code for recycling bins:

Green: glass.

Yellow: plastic and cans.

Blue: paper and cardboard.

And now I leave you with the rap you are performing in drama lessons.

And remember,  help the environment by recycling!

MAKE A GOOD CHOICE, MAKE A BIG DIFFERENCE!

 

 

NUEVA UNIDAD : “¿DE QUÉ ESTÁS HECHO?”

Los alumnos de segundo iniciamos la Unidad de Indagación “¿De qué estás hecho?”

Idea central: Los recursos naturales y los materiales son esenciales para la vida y el medio ambiente.

Durante el desarrollo de esta unidad  Observaremos y entenderemos las características que poseen algunos materiales. Conoceremos cómo se comportan los materiales ante diferentes situaciones. Asumiremos la responsabilidad del buen uso y reutilización de los materiales.
