Slide 8 / 118 Mass In our definition of matter, we included the word mass. To understand mass, imagine two objects moving. How hard would it be to stop it or change their directions? If the bike and truck are both going at the same speed, which is harder to stop?
Slide 9 / 118 Mass Correct! The truck is harder to stop. What is the difference between the truck and the bike that makes the truck harder to stop? (move the truck for the answer) the truck has more mass How is mass related to matter?

Slide 62 / 118 Review: Material Matters! We use different materials for different purposes because they have different properties. It is important to study materials to find out all about their properties. You can test materials to find out more about their properties. Knowing about properties helps you select the right material for the job.

Slide 73 / 118 Define Matter Think back to the beginning of this unit. Fill in the blanks in the statement below. Matter is anything that and has.
Slide 74 / 118 States of Matter Remember this picture from earlier in this unit? Lets look at three specific examples from it. an apple juice a juice box a ball air inside ball air inside balloon steam from soup hot air balloon a brick soup
Slide 75 / 118 States of Matter What do you notice is different about these examples? air inside balloon an apple juice Air is a gas Apple is asolid Juice is a liquid Move this box to reveal the answer after you have talked about it at your table.
Slide 76 / 118 Three States of Matter We can describe all matter by putting it into one of these three categories. List 3 examples under each category. Solid Liquid Gas
Slide 77 / 118 Solids Solids have a specific shape, mass, and take up a set amount of space. These are all examples of solids.
Slide 78 / 118 Solids Particles in a solid are held together tightly. This is why solids often keep the same shape and size. You can mold, cut, tear, and shatter solids.
Slide 79 / 118 Liquids Liquids also have mass and take up a certain amount of space. Liquids are different from solids because they do not have just one shape. They can be poured and take the form of the container they are held in.
Slide 80 / 118 Liquids Particles in a liquid are not packed as tightly and move freely. This is why liquids can be poured and can flow into any shape.
Slide 81 / 118 Gases Gases have mass and spread out to fill any space. They do not have a specific shape. What kind of gas do you think these soldiers are filling that balloon with?
Slide 82 / 118 Gases Most gases are invisible. You can not hold them or pick them up. You can't see wind, but you can see leaves blow. You can't see gas, but you can fill a balloon with it. You can't see air, but you can see bubbles filled with it.
Slide 83 / 118 Gases Particles in a gas are not held together at all. They are spread far apart.
Slide 84 / 118 Click the box below to see how particles are spaced apart in matter.

Slide 86 / 118 24 The three states of matter are liquid, gas and. A solid B material C mass
Slide 87 / 118 25 take the shape of their containers. A solids B gases C liquids
Slide 88 / 118 26 Which example proves gas takes up space? A filling a balloon B spilling hot tea C dropping a hard brick

Slide 93 / 118 Changing States of Matter Return to Table of Contents
Slide 94 / 118 Matter State Changes Matter can change from one state to another by changing temperature. Adding heat makes particles move faster Taking away heat makes particles move slower When particles move faster or slower because of temperature, they can change states.
Slide 95 / 118 Click the box below to see a demonstration of particle movement
Slide 96 / 118 Matter State Changes Taking away heat causes a liquid to change into a solid At your table, explain how juice pops are made. What do we call it when a liquid changes into a solid?
Slide 97 / 118 Matter State Changes Heat can change a solid to a liquid Now talk about what happens when you have an ice pop on a hot day. What do we call it when this happens?
Slide 98 / 118 Matter State Changes Heat can change a liquid to a gas. Talk with your table about what happens when you boil water on the stove. What exactly changes state? From what to what?
Slide 99 / 118 Matter Changes liquid cold Solid We just saw that temperature causes matter to change states. Solid heat liquid liquid heat gas

Slide 108 / 118 Types of Changes to Matter Return to Table of Contents
Slide 109 / 118 Types of changes Some changes can be reversed, or undone. Use the ice pop example to describe how changes to matter can be undone. Be sure to use the words heat and cool in your description.
Slide 110 / 118 Types of changes Some changes are irreversible, they cannot be undone. To make pancakes, the batter is heated and turns into a solid pancake. 1. 2. 3. 4. Is is possible to melt the pancake to turn it back to a liquid?
Slide 111 / 118 Irreversible changes Rusting and burning are examples of irreversible changes.

Slide 113 / 118 34 The ice in the glass turned to a liquid. What kind of change is this? A reversible, can be undone B irreversible, cannot be undone
Slide 114 / 118 35 Freezing causes liquids to change into. A liquids B solids C gases
Slide 115 / 118 36 Look at the pictures. Is this an example of a reversible or irreversible change? A reversible B irreversible
