  1. New Six Weeks New Approach #1 ] Please be ready for class when the bell rings

  2. New Six Weeks • Lessons will be more concise/coherent • Posted online daily with date/objective ( or topic ) • I will label Bellwork, Notes, etc • Late penalty of 2 points per day for assignments • Days we do not meet COUNT!! • Makeup work when absent • Have 5 days ( days we do not meet count ) for classwork and labs • Have 3 days for quizzes and tests

  3. New Six Weeks • Will not check notebooks any more • Assign few homework problems each class • Online venue still a possibility • Will discuss the following class period • May have time at the end of class ( USE IT!! ) • Will have open notes quizzes ( 1-2 times per week )

  4. Need to create Variety of Groups • I will create several different types of groups with varying numbers • 2 ( Partners ) • 3 ( Study Groups ) • 4-5 (Lab Groups ) • Based on strengths/weaknesses of students • Based on time/lesson

  5. 09/24/12 - Bellwork • Here is a list of common phase changes • Label whether they absorb or release energy • That is, when they occur • Fog Formation • Dew Forming on Grass • The Dew Drying when Sun comes out • Ice or Snow we might see this winter

  6. 09/24/12 - Bellwork • Here is a list of common phase changes • Label whether they absorb or release energy • That is, when they occur • Fog Formation - release • Dew Forming on Grass - release • The Dew Drying when Sun comes out - absorb • Ice or Snow we might see this winter - release

  7. 09/24/12 - Bellwork • Here is a list of common phase changes • Label whether they absorb or release energy • That is, when they occur • Fog Formation – release ( condensation ) • Dew Forming on Grass – release ( same ) • The Dew Drying when Sun comes out – absorb (?) • Ice or Snow we might see this winter – release (?)

  8. 9/26/12 - Bellwork • When you change liquid water to water vapor ( or steam ) do you add or remove heat? • How is Energy Conserved?

  9. 9/26/12 - Bellwork When you change liquid water to water vapor ( or steam ) do you add or remove heat? How is Energy Conserved? Electricity is used ( energy is lost ) and water gains energy ( energy lost is same amount of energy gained by water )

  10. Study Groups • Go to your station – take notebook/paper!! • Someone login to labtop • Search for “PhET” – choose top hit ( goto website ) • Search for the “States of Matter” simulation • Not the “basic” link

  11. Lab Activity • Choose water as your material • Choose the solid state • Question – what kind of pattern do you see? • Change the state to liquid • Question – How does the pattern change?

  12. Lab Activity • Add heat ( use setting at bottom ) • What Happens to Particles/State? • Change the state to gas • Question – How does the pattern change? • For each state, how did the motion of the particles change for each transitition?

  13. Challenge Questions • Why might full containers of water explode or burst when put in the freezer? • Why do Ice Cubes FLOAT in liquid water?

  14. Activity ( Outside? ) • We will go outside and observe around campus • In your notes, write down 8 objects you see • Label any chemical/physical properties • Label any chemical/physical changes • Label 2 of the Physical changes by name • Also label whether energy is absorbed or released

  15. Here’s What to Start With

  16. What did we see?

  17. Practice - Study Guides • Pg 10 ( #s 1, 2, 5 ) • Pg. 11 ( #s 1, 2, 3, 4 ) • Will Use Partners

  18. Open Notes Quiz – 9/25/12 • Look in notes over outdoor activity (from today) • 1] Write down 4 objects and list a Property and Change for Each • 2] For one of these objects, list a State-Change • 3] When you melt ice into water, do the particles get more or less ordered? • 4] When this melting occurs, does the water absorb or release energy?

  19. Open Notes Quiz – 09/26/12 • 1] Look at info written down during outdoor activity. Write down 2 objects you observed. For one, write a Chemical Change you observed; for another write down a State-Change you observed. • 2] When you evaporate water into gas, do the particles get closer or further apart? • 3] When this boiling occurs, do you add or take away energy ( does the water absorb or release energy )?
