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 WithObject Phys/Chem

Property?Phys/Chem Change?

State-Change

tree Brown / 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 )?
