12 Material AICLE: 6º de Primaria: Matter

Would you make a …. from..…?

MATTER is anything that has weight and takesMatter is everything that we can see, touch, taste and smell in our daily lives. You see matter everywhere you look. The clouds are made up of matter (mostly water!), the Earth is made up of matter, your notebook is made up of matter and so are you!

Matter can be broken into very little pieces. The smallest pieces of matter are called molecules.

Matter has properties

Property is a characteristic that describes matter. Volume and density are properties of matter.

Color, flexibility and shape are other characteristics of matter.

Volume is the amount of space that matter takes up.

Density is the property that describes how much matter is in a given space, or volume.

Properties describe matter. A block of wood, a rubber glove, milk and air all have properties.

All of the matter on Earth is in one of three states: solid, liquid or gas.

A wood block is______. A solid has a certain ______ and ______. Solids are ______. Wood blocks do not change size or shape. Other examples of solids arethe computers, desks and the floor. Water can be ______ too. You know that when we freeze water it becomes ______ which is solid.Can water be a ______ too? What should we do to transform liquid water into gas?

- Solids stay in one place and can be held.- Solids keep their ______. They do not flow like ______.- Solids always take up the ______ amount of space. They do not spread out like gases.- Solids can be cut or shaped.- Even though they can be poured, sugar, salt and flour are all solids. Each particle of salt, for example, keeps the same shape and ______.- Heating certain ______ will cause them to turn into liquids.- Cooling certain ______ will cause them to turn into solids.

Milk is a liquid. It has size, or volume. Volume means it takes up space.But milk doesn’t have a definite shape. It takes the shape of its container.

- Liquids can flow or be poured easily. They are not easy to hold.- Liquids change their shape depending on the container they are in.- Even when liquids change their shape, they always take up the same amount of space. Their volume stays the same.- Heating liquids will cause them to turn into a gas.- Cooling liquids will cause them to turn into a solid.- Heating solids will cause them to turn into a liquid.- Cooling gases will cause them to turn into a liquid.

Examples of liquids:

Look and answer:

What shape does milk have when it’s in a glass? What shape does it have when it’s in a bottle? in a brick?

13) Listen to the text and read it out loud  

If you run very fast for one minute you will notice how hard you’re breathing.What you’re breathing is air that contains oxygen. You need oxygen to live. That’s why you can only hold your breath for a certain amount of time.

You can’t see oxygen. It’s invisible. It’s a gas. A gas is matter that has no shape or size of its own. Gases have no color.

Gases are all around you. You can feel gas when the wind blows. The wind is moving air.Air is many gases mixed together. Gas spreads very easily and quickly.

- Gases are often invisible.

- Gases do not keep their shape or always take up the same amount of space. They spread out and change their shape and volume in order to fill up whatever container they are in.

- Gases can be squashed.

- Heating liquids will cause them to turn into a gas.

- Cooling gasses will cause them to turn into a liquid.

The atmosphere surrounds the Earth and protects us by blocking out dangerous rays from the Sun. The atmosphere is a mixture of gases that becomes thinner until it gradually reaches space. It is composed of Nitrogen (78%), Oxygen (21%), and other gases (1%).

Oxygen is essential to ________ because it allows us to breathe. Some of the oxygen has changed over time and is now in the ozone. The ________ ________ filters out the Sun’s harmful rays. Recently, there have been many studies on how humans have caused a hole in the ozone layer.

Humans are also affecting Earth’s atmosphere through the greenhouse effect. Due to increases in gases, like carbon dioxide, that trap heat from being radiated from the Earth, scientists believe that the atmosphere is having trouble staying in balance, creating the _______________ ________ .

The atmosphere is divided into five ________ depending on temperature and height. Most of the ________ formations and ________ are found in the first layer.

16) Density, volume and weight experiment:    

You need:- A precession scale- A sponge, a piece of iron rubber and a styrofoam ball- An empty balloon and an inflated balloon- A bottle of water and a bottle of oil

We are going to cut the same sized pieces of all these solids,and then we are going to weigh them.

After that we will weigh the liquids.

Take notes:

- Which of the solid objects is the heaviest?- Which is the lightest?- Which balloon is heavier: the empty one or the inflated one?- Do you know why?- Which is heavier: a liter of oil or a liter of water?- So, what will happen if you mix oil and water? Why?
