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

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

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 )

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

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

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

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 (?)

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

9/26/12 - 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 )

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

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?

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?

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

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

Here’s What to Start With ObjectPhys/Chem Property? Phys/Chem Change? State-Change treeBrown / Flammable Leaves changing? Moisture evaporating?

What did we see?

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

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?

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 )?
