# Find out about Matter!!

Introduction
1. What happens with a glass of water if we leave it under the sun during a couple of days? How is this phenomenon called?
2. When an ice cube is melt, we already know it becomes water, but has the number of its particles changed? Where is the difference between ice and liquid water?
3. When we turn on the heater in our car in winter, what happens with the windows? Is the water inside or outside the car? How is this phenomenon called?

Here you can find some resources which will be helpful in your tasks:

Make a word-map using an online tool such as Mindomo or Popplet with the properties, states and changes in matter.

Process

1. Here you have the lyrics of the Matter Song but there are some gaps…Listen to the song and complete it to sing it and learn about matter. Click the link below to listen to this song and enjoy!

 THE MATTER SONG   Now there’s a ___________here before me. What kind of matter could it be? I’ll list its properties: it’s hard. It has its own shape. And it’s visible. So what kind of matter could it be? _________! (right!) So when I wonder what can the matter be, I’ll make a list of its______________. And when I’m finished, then I can see If it’s solid or it’s liquid or it’s__________! They’re all around us in every place. They all have ___________and they take up ____________ But everyone is a special case: It’s a solid or a liquid or a gas! There’s another matter here before me. What kind of matter could it be? I’ll list its properties: it can be poured. It changes shape. And it’s visible. So what kind of matter could it be? __________!(right!) So when I wonder what can matter be, I’ll make a list of its properties. And when I’m finished, then I can see If it’s solid or it’s liquid or it’s_________! They’re all around us in every place. They all have mass and they take up space But everyone is a special case: It’s a solid or a liquid or a gas! There’s one more matter here before me. What kind of matter could it be? I’ll list its properties: it’s filling the room. It changes shape. And it’s invisible. So what kind of matter could it be? GAS!(right!) So when I wonder…

1. Watch this video and complete this a Compare and Contrast Matrix about the three states of matter

 STATES OF MATTER SOLIDS LIQUIDS GAS MASS VOLUME SHAPE ATOMS

1. Answer these questions. You can find the answers in www.chemistry.about.com

• Fire state of matter. What is the state of matter of fire?
• Is dissolving sugar in water a chemical or physical change?
• Write 3 examples of physical changes:
• Write 3 physical properties:
• Write 3 chemical properties:

1. Complete this T-Diagram about changes in matter.

PHYSICAL CHANGES  CHEMICAL CHANGES

Create a word-map considering all the content worked during the unit of Matter. You can use Popplet or Mindomo.

Evaluation

Students should be able...

• To distinguish the concepts of matter and properties
• To know the main properties of matter: mass, volume, density, flexibility, hardness
• To describe an object considering the material it is made of and its properties
• To relate buoyancy to density, mass and volume
• To distinguish the three states of matter
• To know the changes in matter: physical and chemical.
Conclusion

And now, could you answer these questions?

1. What happens with a glass of water if we leave it under the sun during a couple of days? How is this phenomenon called?
2. Why do objects float?
3. When an ice cube is melt, we already know it becomes water, but has the number of its particles changed? Where is the difference between ice and liquid water?
4. When we turn on the heater in our car in winter, what happens with the windows? Is the water inside or outside the car? How is this phenomenon called?
