  1. DO NOW!!! • Get your assessment binder. • Open your notebook to “How am I Doing?” • Make sure you have these recorded Sept. 11 SIS Quiz __________, parent sign Sept. 21 Waves, Sound, Light (Pre) _____, sign Oct. 12 Quiz on Waves __________, sign Oct. 19 Quiz on Waves and Light _____, sign **** Quiet Reading

  2. Set up 2nd Quarter Section • 1st page Blank for now • Left page – Goals and Expectations • Right page – 2nd Quarter Objectives • Left and Right page – How am I doing? • Left and Right page – Table of Contents

  3. RIGHT PAGE 56October 24, 2012 Focus: Phase Changes Objective: 6.P.2.2- I will be able to explain the effect of heat on the motion of atoms what happens to particles during phase changes HW:complete foldable, eye story Warm-Up: What did you learn from the Energized Guyz Show?

  4. STATES OF Chem4Kids - States of Matter MATTER

  5. Do Molecules Move? Yes, they sure do! How do they move? It depends on whether they are in a solid, liquid, or gas

  6. Molecules in Solids: • Molecules are packed tightly together • Have very little energy

  7. Molecules in Liquids: • Molecules are loosely packed • Have medium energy

  8. Molecules in Gasses: • Molecules are spread far apart • Have LOTS of energy

  9. What is the main difference between solids, liquids, and gases?

  10. When energy is added, particles move faster and spread apart! When energy is taken away, particles move slower and get close together! Add or Subtract Energy. . .

  11. Gas (MOST energy) Liquid (Medium energy) Solid (LEAST energy)

  12. Video Questions: What makes molecules get close together or spread far apart? What makes molecules move? http://teacher.scholastic.com/activities/studyjams/matter_states/

  14. Phase Changes • When you change the amount of heat energy in a substance it will change from one phase to another.

  15. This is a graph of the temperature of water that starts as ice and ends up as steam. Temperature Heat Energy

  16. What is happening on the slopes of the graph? Temperature Heat Energy

  17. Adding Heat Energy: Temperature Gas Boils Liquid Melts Solid Heat Energy

  18. Removing heat energy: Temperature Gas Condenses Liquid Freezes Solid Heat Energy

  19. Removing heat energy: Temperature Gas Boils Liquid Condenses Melts Solid Freezes Heat Energy

  20. Vocabulary Connections Boiling Point Melting Point Melts Boils Solid Liquid Gas Condenses Freezes Freezing Point Condensation Point

  21. STATES OF MATTER • The Four States of Matter • Four States • Solid • Liquid • Gas • Plasma

  22. STATES OF MATTER • Based upon particle arrangement • Based upon energy of particles • Based upon distance between particles

  23. Kinetic Theory of Matter Matter is made up of particles which are in continual random motion.

  24. STATES OF MATTERSOLIDS • Particles of solids are tightly packed, vibrating about a fixed position. • Solids have a definite shape and a definite volume. Heat

  25. STATES OF MATTERLIQUID • 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. Heat

  26. STATES OF MATTERGAS • Particles of gases are very far apart and move freely. • Gases have an indefinite shape and an indefinite volume. Heat

  27. PHASE CHANGES

  28. PHASE CHANGES

  29. But what happens if you raise the temperature to super-high levels…between 1000°C and 1,000,000,000°C ? Will everything just be a gas?

  30. 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

  31. STATES OF MATTER 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

  32. Some places where plasmas are found… 1.Flames

  33. 2. Lightning

  34. 3. Aurora (Northern Lights)

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