  1. MATTER Changes in State of Matter: Freezing, Melting, Evaporation, Condensation, & Sublimation DAY ONE

  2. SPONGE Answer Questions 1-2. Write the Letter of the Correct Answer Only 1. The measure of how much space an matter takes up is______ (a) Matter (b) Mass (c) Volume (d) Weight 2. A measure of how much matter an object contains is____. (a) matter (b) mass (c) weight (d) volume

  3. CONTENT STANDARD & ELEMENT Standard: S8P1: Students will examine the scientific view of the nature of matter. Elements: (a).Distinguish between atoms and molecules (c). Describe the movement of particles in solid, liquids, gases and plasma states

  4. Language of the Standards (Today's Vocabulary) • Solids • Liquids • Gases • Condensation • Sublimation • Evaporation • Freezing Point • Melting • Boiling Point

  5. Why Is This Important ? Today I will learn about……. How to differentiate between the Changes in the Phases/States of Matter (Evaporation, Condensation, Sublimation, Melting & Freezing). This is important because it will help me to gain a better understanding of the differences between (Evaporation, Condensation, Sublimation, Melting & Freezing)and that matter changes when heat energy is added.

  6. Essential Question 1. How do we differentiate between phases changes: Evaporation, Condensation, Melting, Freezing & Sublimation?

  7. But First...Do you Remember ? HOW DO WE MEASURE MATTER ?

  8. But First...Do you Remember ? Volume • . How much space something takes up • Graduated Cylinder • Volume never changes regardless of location Mass Weight • All are used to • measure matter • Gravitational force between the object and another object. • Weight changes depending on location • NEWTONS • How much 'stuff' an object is made of • Balance Scale • Mass is constant regardless of location. • GRAMS

  9. But First...Do you Remember ?Particle Behavior of Solid, Liquid & Gas Molecules

  10. Particle Behavior of Matter

  11. ACTIVATOR Dry Ice Facts • Dry ice is what SUBLIMATION (solid to gas) is all about !!!! • Dry ice is Carbon Dioxide (CO2) • Yes, that’s the same gas you exhale when you breathe and the same gas trees use in photosynthesis! • CO2 is a naturally occurring molecule composed of two oxygen atoms bonded to one carbon atom. • At room temperature it is a clear odorless gas. • When warmed, goes from solid to gas; it doesn't melt… it does not evaporate…it sublimates

  12. MORE Dry Ice FACTS !!!!

  13. Why do they call it dry ice?? Observe the dry ice as your teacher walks around the room. What do you notice that is unusual about the dry ice?

  14. Sublimation • This occurs when a solid changes phase directly to a gas. There is no liquid phase. This is why it is called “dry” ice because it never gets wet like regular ice!

  15. How do they make dry ice?? • Every substance has a different freezing point. Companies that make dry ice simply cool air to the point where the carbon dioxide can liquefy and then become a solid. • It has all kinds of practical uses: fire extinguishers, carbonated drinks, shipping things that have to stay cold (ice cream), fog special effects, etc.

  16. Lab Safety Procedures • Dry ice is very cold (-109 degrees Fahrenheit)…so cold its acts as if its HOT !!!! • Wear protective gloves and goggles. • Store dry ice in containers that allow the gas to escape…leave the lid slightly open

  17. The Learning Period PHASE CHANGES LIQUID PLASMA SOLID GAS Tightly packed, in a regular pattern Vibrate, but do not move from place to place Close together with no regular arrangement. Vibrate, move about, and slide past each other Well separated with no regular arrangement. Vibrate and move freely at high speeds Has no definite volume or shape and is composed of electrical charged particles

  18. STATES OF MATTERPLASMA • A plasma is an ionized gas. • A plasma is a very good conductor of electricity and is affected by magnetic fields. • Plasmas, like gases have an indefinite shape and an indefinite volume. • Plasma is the • common state • of matter

  19. 1. Aurora (Northern Lights)

  20. 2. Lightning

  21. Some places where plasmas are found… 3.Flames

  22. 4. The Sun is an example of a star in its plasma state

  23. PHASE CHANGES

  24. PHASE CHANGES

  25. The Learning Period CHANGES OF PHASES OF MATTER : http://www.bgfl.org/bgfl/custom/resources_ftp/client_ftp/ks3/science/changing_matter/changingmatter.swf

  26. The Learning Period Lets See this UP CLOSE……..PHASE CHANGE DEMOS • Sublimation • Condensation • Evaporation • Melting

  27. Sublimation:Solid to Gas (heat goes into solid as it sublimates) • What would happen if I added some dry ice to my apple juice? • Go ahead, make a prediction. Guess!!!

  28. Boil, Boil, Toil & Trouble!! • The heat from the apple juice is transferred to the dry ice causing it to sublimate faster (that’s the boiling effect you see & hear). • But where does the carbon dioxide gas go?? • Can you guess what has happened to our apple juice? Try some and see!

  29. Condensation: Gas to Liquid (heat leaves the gas as it condenses)Evaporation: Liquid to Gas (heat goes into the liquid as it vaporizes ) Condensation Evaporation

  30. Melting: Solid to Liquid (Heat goes into the solid as it melts).

  31. Independent Work Session(CFU) QUESTIONS 1. Which describes a change from gas to a liquid? (a) evaporation (b) condensation (c) freezing (d) Sublimation 2. Why does the outside of a glass of iced tea sometimes get moist? (a) Water molecules from the tea pass through the pores in the glass. (b) Water vapor in the air turns to liquid as it condenses on the cold glass. (c) Glass attracts water droplets that are floating in the air. (d) Melting ice creates more water than the glass can hold.

  32. 3. Temperature measures_________. (a) how slow particles move (b) how hot something is (c) the temperature of something (d) how fast particles move 4.

  33. CLOSING “I WONDER…..” Directions: Based on what you learned today paper write down……. What did I notice… What did I expect… I wonder what would happen….

  34. HOMEWORK 1. Review the Test 1 STUDY GUIDE for the first unit test on NEXT WEEK …….

  35. MATTER Changes in State of Matter: Freezing, Melting, Evaporation, Condensation, & Sublimation DAY TWO

  36. SPONGE • Clear your desk • Study graphic organizers & all notes for QUIZ

  37. CONTENT STANDARD & ELEMENT Standard: S8P1: Students will examine the scientific view of the nature of matter. Elements: (a).Distinguish between atoms and molecules (c). Describe the movement of particles in solid, liquids, gases and plasma states

  38. Language of the Standards (Today's Vocabulary) • Solids • Liquids • Gases • Condensation • Sublimation • Evaporation • Freezing Point • Melting • Boiling Point

  39. Why Is This Important ? Today I will…….assess what I have mastered about states of matter and changes in those states. This is important because it is important for me understand what standards I have mastered.

  40. Essential Questions 1. How do we differentiate between Solid, Liquids & Gas ? 2. How do we differentiate b/w Evaporation, Condensation, Melting, Freezing & Sublimation?

  41. QUIZ TODAY AGENDA 1.QUIZ REVIEW (Staircase Review & Sorting Activity) 2. QUIZ TIME 3. GRADES & Feedback

  45. MATTER Classifying Matter: ELEMENTS & THE PERIODIC TABLE DAY THREE

  46. EQ: How is the periodic table arranged? TIWL: how the periodic table is arranged, because it is arranged by its physical and chemical properties. • SPONGE: • How many elements are listed on the periodic table of elements? • A.28 • B.60 • C.72 • D. more than 100 • *Place Homework in the center of table
