1 Catalyst: How can you determine if something is in a solid, liquid or gaseous state? States of Ma*er 9/22/16 Reflec3on: 9L 9R

2 Phases Demonstration 1. How did the food coloring behave differently in the 3 temperature liquids? 2. Why did the food coloring behave differently in the 3 temperature liquids? 3. Can you relate this to solids liquids and gasses? 4. Can you relate this to molecular mo3on in solids liquids and gasses?

3 Catalyst: How can you determine if something is in a solid, liquid or gaseous state? States of Ma*er Liquid Solid Reflec3on: Gas 8L 8R

4 STATES OF MATTER SOLIDS Particles of solids are tightly packed, vibrating about a fixed position. Solids have a definite shape and a definite volume.

5 So what is a solid? Solids are usually hard because their molecules have been packed together. The closer your molecules are, the harder you are.

6 Catalyst: How can you determine if something is in a solid, liquid or gaseous state? Reflec3on: States of Ma*er Liquid Write these notes UNDER your SOLID FLAP Solid Particles of solids are tightly packed, vibrating about a fixed position. Solids have a definite shape and a definite volume. Gas 8L 8R

7 Lets Be Solid! 1. Pretend that this classroom is Just a container. 1. If we are each a single water molecule, how should be behave in this cube to demonstrate solid ice? 2. You have 20 seconds to organize and mobilize!

8 STATES OF MATTER LIQUID Particles of liquids are tightly packed, but are far enough apart to slide over one another. Liquids have an indefinite shape and a definite volume.

9 So what is the big deal about liquids? Solids are hard things you can hold. Gases are floa3ng around you and in bubbles. What is a liquid? Water is a liquid. Your blood is a liquid. Liquids are an in- between state of ma*er. They can be found in between the solid and gas states. Liquids have three main proper3es: It does not have a definite shape. It has a definite mass. It has a definite volume.

Reflec3on: States of Ma*er Liquid Particles of liquids are tightly packed, but are far enough apart to slide over one another. Liquids have an indefinite shape and a definite volume. Gas Solid Write these notes UNDER your Liquid Flap 8L 8R

11 Lets Be Liquid! 1. Pretend that this classroom is just a container. 1. If we are each a single water molecule, how should be behave in this cup to demonstrate liquid water? 2. You have 20 seconds to organize and mobilize!

12 Particles of gases are very far apart and move freely. STATES OF MATTER GAS Gases have an indefinite shape and an indefinite volume.

13 Gases don't keep their shape, and don't keep their volume either. If you had one liter of a gas, such as nitrogen, and you pumped it into a 2- liter jar, the gas would swell to fill up the whole 2 liters.

15 Lets Be Gas! 1. Pretend that this classroom is just a container. 1. If we are each a single water molecule, how should be behave in this balloon to demonstrate gaseous water (water vapor)? 2. You have 20 seconds to organize and mobilize!

16 One state of ma*er can become another and another and another

17 How do we change from one state of ma9er to another?

18 HEAT! What is heat? Most of you probably have felt hot or cold, but what makes something hot or cold? Heat is a form of energy. Heat is the energy of moving molecules.

19 A 4 th state of ma*er?? Plasma! A lot like gas but it s made of posi3vely and nega3vely charged par3cles. Not bound to a nucleus, free to move around the system. Natural plasmas are not common but man made plasmas are (florescent lights)

20 Catalyst: How can you determine if something is in a solid, liquid or gaseous state? States of Ma*er Liquid Solid Reflec3on: Tell the story of a water molecule from ice cube to gas. 8L Gas 8R

21 Comic Strip Create a 6 frame comic strip giving the first person perspective of a water molecule changing from solid to liquid to gas.

22 The Phamazing Phases Lab There will be 4 sta@ons and you will rotate between them, 15 minutes each. You MUST LISTEN to ALL of the direc3ons so you know what s happening at each sta3on!

23 Catalyst: Look at the lab materials at your desk. What are some safety rules you should follow? Phamazing Phases Lab! 9/26/16 Station 1 Station 2 Reflection: Station 3 Station 4 10L 10R

24 1. Sublime Sublima3on You will be observing and recording the 3me it takes for your piece of dry ice to change from a solid to a gas! 1. With a stop watch please 3me how long it takes for your piece to sublime. 2. Draw a picture and record observa3ons

25 2. Nerdtas3c Non Newtonium Fluid You will be crea3ng and experimen3ng with Oblek! 1. Put 20 ml of cornstarch into a red cup. Add 6 ml of water. Add several drops of your chosen color. Mix with a chops3ck. 2. Take 3me to explore 3. KEEP IT NEAT! 4. Is this a solid or a liquid explain? 5. Draw a picture depic3ng both

26 3. Phantas3c Phase Changes You will be observing and recording the temperature change water undergoes from solid ice to gas. 1. You will be recording the temperature every minute from solid ice to boiling rapidly with gas crea3on. 2. Create a graph to depict your results

27 4. Bulging Balloon You will examine balloons filled with a solid, liquid and gas. 1. Examine the three balloons 2. Create a drawing for each 3. Write observa3ons on how the different phases fill the balloons.

28 Catalyst: Look at the lab materials at your desk. What are some safety rules you should follow? Phamazing Phases Lab! 9/25/16 Station 1 Station 2 Reflection: What phenomena did you witness at each of the 4 stations? Summarize using your phase change foldable. 10L Station 3 Station 4 10R
