1. Properties of matter Create a page titled States of matter in your journal and record your observations about the set up in the front of the classroom

2. What two things must be true for all matter? What are our 3 states of matter...

3. So.. if gas is a state of matter, and all matter has mass…. then Gasses must have masses Record your thoughts and the results of the demonstration

4. 1.Read the min-book about the 3 states of matter, and do the “a matter of states activity at a level 0 i.any time that it says to “use 16 punch outs” we will be coloring in 16 squares instead. 1.Create a 3 branch tree map chart to record the names and properties listed for each state of matter. a.List the properties that you read for each in the mini book 1.You may work with a partner at your table once both have finished reading to a.Complete the “Solid liquid or gas” job 1 table” i.Place the examples given on your tree map under the right branch b.If you do not finish both sides, place them in your science folder, we will continue tomorrow

5. HOMEWORK “whats the matter” video you must also click on the link to answer the questions about the video

6. Get out worksheet from yesterday You will have the first 10 minutes of class to continue working on it, we will go over it together and correct any misunderstandings together.

7. Properties of Matter Learning target I can classify matter based on its physical state, know the properties of each state, and understand how matter can change state.

8. Matter ● Exists in one of three main states: solid, liquid, or gas

9. State of matter SolidLiquidGas Molecules Shape Volume examples

10. State of matter SolidLiquidGas Moleculesmolecules are tightly packed ShapeConstant shape VolumeConstant volume examples

11. So what is a solid? ● Solids are usually hard because their molecules have been packed together, and move the least. Solids also can hold their own shape. ● Constant volume, and shape

12. ● A rock will always look like a rock unless something happens to it. The same goes for a diamond. Even when you grind up a solid into a powder, you will see little tiny pieces of that solid under a microscope.

13. State of matter SolidLiquidGas MoleculesTightly packed molecules Fairly close, can move past each other ShapeConstant shapeTake the shape of their container VolumeConstant volume examples

14. What is a liquid? ● Water is a liquid. Your blood is a liquid. Liquids are an in-between state of matter. They can be found in between the solid and gas states.

15. The molecules are stuck together, but not jammed together like solids. Liquids will take the shape of any container, because the molecules can move but its volume will always stay the same

16. State of matter SolidLiquidGas MoleculesTightly packed molecules, dont move Fairly close together, and can slide past each other Spread far apart, can move quickly ShapeConstant shapeTakes the shape of the container Take the shape of their container VolumeConstant volume Fills the container examples

17. LOOKING FOR A GAS? ● Gas is everywhere. ●Molecules of a gas move the most and are spaced out the farthest. ● Gases take their containers shape and volume. ● Think about a balloon. No matter what shape you make the balloon it will be evenly filled with the gas atoms.

19. States of matter

20. As temperature increases, so does the movement of the molecules.

21. Matter ● Can be changed from one state to another and back by heating or cooling

22. Changes to the state of matter ● Solid ● Liquid ● Gas Think back to the water cycle to see if you can fill in what temperature change needs to happen to cause a change in the state of matter.

23. Changes to the state of matter ● Solid ● Liquid ● Gas Solid to Liquid = Liquid to Solid = = Liquid to Gas = = Gas to Liquid = Different materials have different properties that cause them to change states at different temperatures. At room temperature is water a liquid or solid? What about Chocolate?

24. Changes to the state of matter ● Solid ● Liquid ● Gas Solid to Liquid = Melting Liquid to Solid = freezing = 0C, 32F Liquid to Gas = boiling = 100C, 212F Gas to Liquid = condensing Different materials have different properties that cause them to change states at different temperatures

25. Salt investigation Lets take a look at jar of salt. Just using your naked eye think about the following. Does it take the shape of its container?

26. Salt investigation Lets take a look at jar of salt. Just using your naked eye think about the following. Does it take the shape of its container? Now using the magnifying glasses look again, you should see tiny spaces between each grain of salt. Very small solids may seem like liquids sometimes, but when you look closer, they still have a constant shape.

27. Lets change some matter ● Ice (solid form of H20) ● Crayon (solid form of wax) ● Chocolate (solid form of… chocolate)
