Properties of Matter

1. Properties of Matter Vocabulary Introduction Mullins Grade 3

2. Temperature The degree of hotness or coldness of a body or environment. A measure of the average kinetic energy of the particles in a sample How hot or cold something is

3. Solid • Of definite shape and volume; not liquid or gaseous

4. Liquid • A state of matter, neither gas nor solid, whose atoms move freely, and flows and takes the shape of its container

5. Matter • Objects that take up space and have mass are called matter. Everything around you is made up of matter. Chocolate cake is made up of matter. You are made of matter. • If you are having trouble understanding matter, look all around you. You can see matter makes up the walls of your house and your classroom. Matter is large and matter is small. Do you get it yet?

6. Degree • one of the divisions or intervals marked on a scale of a measuring instrument; any of various units for measuring temperature

7. Fahrenheit • Etymology: Daniel G. Fahrenheit • Date: 1753 • : relating or conforming to a thermometric scale on which under standard atmospheric pressure the • boiling point of water is at 212 degrees above the zero of the scale • the freezing point is at 32 degrees above zero,

8. Fahrenheit Vs Celsius • Note temperatures

9. Celsius • Etymology: Anders Celsius • Date: circa 1850 • Water boils at 100 degrees Celsius • Water Freezes at 0 degrees Celsius

10. Mass • often defined as the amount of matter in an object.  Note that mass and weight are not the same thing.  Weight is the force on an object due to the gravitational pull of a planet or other heavenly body.  Mass on the other hand, remains constant, no matter where it is.

11. Volume • the amount of 3-dimensional space occupied by an object

12. Liters • A metric unit of volume equal to approximately 1.056 liquid quarts, 0.908 dry quart, or 0.264 gallon.

13. Grams • a metric unit of weight equal to one thousandth of a kilogram

14. Properties of MatterA property describes how an object looks, feels, or acts • Size • Shape • Color • Texture • Hardness

15. Properties • You use your sense of taste and smell to tell the difference between spinach and an orange. • Physical properties- The measurement of mass and other characteristics that can be seen without changing how that object looks are its physical properties. When you look at oranges, you know that they are oranges because of their color, shape, and smell. Mass, color, shape, volume, and density are some physical properties. The answers to the question about the present are physical properties. • Density is an important physical property. Density is the mass of a substance per unit volume. Volume is the amount of space an object occupies. • Chemical properties- These are properties that can only be observed by changing the identity of the substance. A piece of paper burns and turns to a black substance. After the flame goes out you can no longer burn the new substance. The chemical properties have been changed.

16. Size • the physical magnitude of something (how big it is)

17. Shape • to give a particular form or shape to

18. Color • quality such as red, blue, green, yellow, etc., that you see when you look at something

19. Texture • the way that something feels when you touch it

20. Hardness • the quality or state of being hard

21. Measurements • a size, length, or amount known by measuring something

22. Observations • the act of careful watching and listening • a statement about something you have noticed

23. Evidence • something which shows that something else exists or is true

24. State • the fact of being a liquid, solid, or gas • The "state" of the matter refers to the group of matter with the same properties. In other words, you group the objects together according to their properties.

25. Melting • to change or to cause (something) to change from a solid to a liquid usually because of heat

26. Evaporation • to change from a liquid into a gas

28. Condensation • the process by which a gas cools and becomes a liquid

30. Freezing • to be very cold

31. Solid • The wood block is solid. A solid has a certain size and shape. The wood block does not change size or shape. Other examples of solids are the computer, the desk, and the floor. • You can change the shape of solids. You change the shape of sheets of lumber by sawing it in half or burning it.

32. Liquid • Milk is a liquid. Milk is liquid matter. It has a 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, be poured, and spilled. Did you ever spill juice? Did you notice how the liquid goes everywhere and you have to hurry and wipe it up? The liquid is taking the shape of the floor and the floor is expansive limitless boundary (until it hits the wall). You can't spill a wooden block. You can drop it and it still has the same shape.

33. What about? • What about jello and peanut butter? • You can spread peanut butter on bread, but peanut butter does not flow. It is not a liquid at room temperature. You have to heat peanut butter up to make it a liquid. When you or your mom makes jello, it is first a liquid. You have to put it in the refrigerator so that it becomes a solid. These are yummy forms of matter with properties of a liquid and a solid.

34. Gas • Run in place very fast for a minute. Do you notice how hard you are breathing? What you are breathing is 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 is 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.
