MATTER Matter is ALL Around Us! Matter is anything that takes up space and has mass. Matter is made up of atoms. Atoms are the basic building blocks of matter and make up all objects. Lesson Checkpoint: What is matter made of? States of Matter: Solid, Liquid, and Gas Solid: A state of matter in which molecules are packed tightly together so they can’t move around. Solids always hold the same basic shape. An example of a solid is a rock. Liquid: A state of matter in which the molecules are close together, but are able to move around slowly. Liquids take the shape of whatever they are poured into. An example of a liquid is water. © Copyright NewPath Learning. All Rights Reserved.

Gas: A state of matter in which the molecules are far apart and can move around freely. Gas has no shape. Oxygen is an example of a gas. Lesson Checkpoint: What are the three states of matter? Matter can Change States! Not to New York, California, or Texas…matter change states from solid, liquid, or gas. An example of matter changing states is this: an ice cube begins as a solid…when it melts it becomes a liquid…when the liquid is heated and evaporates it becomes a gas. Types of Changes in Matter A physical change is when matter changes size, shape, or state but doesn’t change the particles that make up matter. An example of physical change: shaping clay into different shapes, you change the shape of the clay but not what the clay is made of. A chemical change changes what particles of matter are made of, which produces a new kind of matter. An example of chemical change: combining baking soda + vinegar = carbon dioxide. The carbon dioxide is the new matter created. © Copyright NewPath Learning. All Rights Reserved. Permission is granted for the purchaser to print copies for non-commercial educational purposes only.

Lesson Checkpoint: What is the difference between a physical change and a chemical change? Properties of Matter Size: A property of matter that tells how big or small an object is. Shape: A property of matter that describes the form of an object. Mass: A property of matter that tells the amount of matter in an object. Volume: A property of matter that refers to the amount of space something takes up. Flexibility: A property of matter that refers to the ability an object has to be stretched without breaking. Buoyancy: The ability an object has to float in a liquid. Lesson Checkpoint: What are three properties of matter? © Copyright NewPath Learning. All Rights Reserved.

Measuring Matter: Units of measurement Meters, centimeters, grams, and liters are all examples of units of measurement. For example, meters and centimeters are units of measurement that can be used to measure the length and width of an object. Tools used for measuring: Many properties of matter can be measured using different tools. For example, volume is an amount of space measured in units. A graduated cylinder can be used to measure volume. Mass can be measured using a pan balance. Lesson Checkpoint: What can be used to measure volume? © Copyright NewPath Learning. All Rights Reserved.

What happens what matter is mixed, dissolved, or combined? A mixture is a combination or two or more substances. The substances in a mixture are physically combined, which means they can be separated. Substances that are mixed together have the same properties as they did before they were mixed together. When you add chocolate chips to your cookie dough before you bake the cookies, you make a mixture of dough and chips. You could separate them again if you had to, since one did not dissolve in the other. That is a mixture. A solution is when one or more substances are dissolved in another substance. A solute is the substance that is dissolved in the solvent. The solvent is the substance that dissolves another substance. Solubility refers to the ability of one substance to dissolve into another substance. When you make lemonade, you combine water, lemon juice, and sugar together to make something new: lemonade. You can’t separate the sugar from the lemon juice or water once you mix them together. That is a solution. Compounds are substances that are made up of more than one type of atom and are chemically combined. For example, carbon dioxide is made up of carbon and oxygen atoms (CO2).

5.1. What is Matter?
Everything that you see, smell or touch around you is matter. Even many things that you cannot see, smell, or touch are matter. Living and nonliving things are made of matter, including our clothing, the food we eat, and even the air that we breathe.
5.2. Describing Matter
Matter is anything that takes up space and has mass. The amount of matter in an object is its mass. Air is matter that you can't see, yet it still takes up space. You can observe this as you blow up a balloon; the air takes up space making the balloon bigger.
5.3. Properties of Matter
Matter can have several different properties. A property is a feature, trait or characteristic and is used to describe an object. For example, two properties that describe a marshmallow are that it's soft and white. While we can use our senses to identify many physical properties of matter, some properties are measurable.
5.4. Properties of Matter Essay
5.5. Properties of Matter - Use your Senses
Physical properties that can be identified with your senses include color, odor, shape, hardness, and texture. For example, you can smell the odor of a rose, observe its color and shape, and feel its texture.
5.6. Properties that Can be Measured
Physical properties that can be measured include mass, volume, density, temperature, and attraction to magnets. Each is measured with a different tool. Scientists use the metric system when measuring matter.
5.7. Sorting Physical Properties of Matter
5.8. Measuring Mass
Mass is the amount of matter in an object. A balance is used to measure mass in metric units of grams or kilograms. For example, to find the mass of a rock, you place it on one side of the balance and the gram cubes on the other side. When the two sides balance each other, the mass of the rock equals the mass of the number of gram cubes on the balance.
5.9. Measuring Volume of a Liquid
Volume is the amount of space an object takes up. There are several tools that can be used to measure volume, such as measuring cups, graduated cylinders, and beakers. The units of measure are milliliters or liters. For example, to measure 50 mL of water, we pour it into a cylinder, until it reaches the 50 mL point marked on the side.
5.10. Finding the Volume of a Solid Object
A graduated cylinder can also be used to measure the volume of solid objects, such as a rock. Fill a cylinder to about the half-way mark with water and read the number on the side. Place the rock in the cylinder and read the water level again. Now, subtract the old reading from the new reading and you have just measured the volume of the rock.
5.11. Measuring Density
Did you ever wonder why some small objects weigh more than larger objects? It depends on their density. Density is a measure of how much matter fits into a certain amount of space. To find out the density of an object divide its mass by its volume. Which do you think has a greater density- a bowling ball or a basketball? If you guessed the bowling ball, you're correct!
5.12. Buoyancy and Density
Buoyancy is a property that demonstrates whether an object is more or less dense than water. Density and buoyancy are closely related. An object will float in water (have buoyancy) if it's less dense than water and sink if it's more dense.
5.13. Measuring Temperature
Temperature is a measure of the hotness or coldness of an object. A thermometer is used to measure temperature in metric units of degrees Celsius (ºC). A thermometer shows the temperature by the up or down movement of a colored liquid inside the thermometer. As an object heats up, the liquid moves up showing a higher temperature. What do you think happens when the liquid moves downward? Is the temperature getting warmer or cooler? You're correct if you answered that it's getting cooler!
5.14. Tools for Measuring Matter
5.15. Attraction to Magnets
Attraction to magnets is also a physical property of matter. Certain objects that contain the metal iron are attracted to magnets. Such objects are magnetic. They include keys, metal paper clips, and iron nails. Magnets do not attract non-magnetic objects made of plastic, wood, or paper.
5.16. Which are magnetic?
5.17. States of Matter
The three states of matter are solid, liquid,and gas. Matter can change from one state to another through a change in temperature.
5.18. Solids, Liquids, and Gases
Solids keep their shape and always take up the same amount of space. Liquids can flow and change their shape depending on the container they are in. Gases, on the other hand, are often invisible and change their volume and shape to fill up the container they are in.
5.19. Solids, Liquids and Gases
5.20. State Changes in Water
When liquid water cools to 0ºC, it changes to solid water called ice. When liquid water heats to 100ºC, it boils and changes to water vapor. This process is called evaporation. Regardless of its state, it is still water.
5.21. Condensation - Gas to Liquid
Condensation is the opposite of evaporation. It takes place when water vapor (gas) cools and changes from vapor to liquid. If you've ever left a cold drink outside on a hot summer day, then you've already seen condensation. As the water vapor in the warm air touches the cold surface of the glass, it cools forming water droplets (liquid) on the glass.
5.22. Changes to Matter
There are two types of changes in matter - physical changes and chemical changes. Let's explore physical and chemical changes along with examples.
5.23. Physical Changes to Matter
A physical change to matter happens when matter changes size, shape, or form, but does not change the type of matter it is. For example, let's say you cut a piece of paper into smaller pieces. The original piece of paper has undergone a physical change; it has changed both shape and size, yet, it is still paper.
5.24. Chemical Changes to Matter
Chemical changes to matter happen when one type of matter changes into another type of matter. For example, the matter that you start with in a campfire is wood. As the wood burns, it undergoes a chemical change - turning into gases and ashes.
5.25. Changes in Matter
5.26. Mixtures
A mixture is a combination of two or more kinds of matter. Each kind of matter doesn't change in the mixture and keeps its own properties. An example of a mixture is a fruit salad with berries, watermelon pieces, and banana slices. The fruit is mixed together, but the berries, watermelon, and banana haven't changed into new kinds of fruit. Mixtures can be separated.
5.27. Solutions
A solution is a type of mixture in which matter is evenly mixed or combined. Lemonade is an example of a solution. It is a mixture of water, lemon juice, and sugar combined evenly into a drink. Once the parts of lemonade are combined together, they cannot be separated. This is one main difference between a mixture and a solution.
