Friday September 9 th Do Now Copy the

Friday, September 9 th Do Now: • Copy the Learning Targets in your binder: “I can… Target 1: Matter 1. 1 Contrast matter energy 1. 2 Classify matter by phase and composition 1. 3 Describe energy transfers associated with phase changes

• Today’s PLAN – 1. 1 Contrast matter and energy – 1. 2 Classify matter by phase and composition – 1. 3 Describe energy transfers associated with phase changes • Today’s DO – We will complete a graphic organizer as notes for phases of matter. – We will takes notes about phase changes/energy changes and complete a flow chart about phase changes and the energy changes involved.

Concept Connection Map: • Word List: principal math teacher homework school students Barren Middle

Pre-Assessment:

Concept Mapping Activity • Create a concept map using the following words: • • Matter Chemistry Solid Liquid Gas Melting Freezing • • • Temperature Energy Mass Volume Density

Taking Notes: please copy… • Matter is anything that has mass and occupies space • Energy is the ability to do work. • All matter has energy stored in the bonds between its atoms. • This is why food (matter) gives us energy to move and live (work).

Phases of Matter • Phases (states) of matter: – Tell us about the arrangement and motion of the particles that make up the matter • • Solid Liquid Gas Plasma

Matter: Video Clip • While viewing consider the states of matter. http: //www. youtube. com/watch? v=guo. U_cu. R 8 EE&feature=related http: //www. youtube. com/watch? v=x. YFAj 50 c 7 x. M

Phases of Matter Notes • You will take notes over the four states of matter on the graphic organizer (chart) given to you.

Solid • Particles (atoms or molecules) are packed closely together and stay in a fixed position • Definite shape and definite volume • Movement consists of vibrating particles staying in place • Particles have least amount of movement and least amount of energy

Liquid • No definite shape, takes on the shape of the container, but it has a definite volume • Particles in a liquid – atoms are loosely bound are free to flow and move, sliding easily over , under, and across each other but remaining in contact w/ one another. • Particles move more than a solid and have more energy than a solid • Viscosity – resistance of a liquid to flow: – high viscosity: “thick”; slow flowing (molasses in January) – low viscosity: “thin”; fast flowing (pouring water)

Gas • No definite shape, takes the shape of the container it is in. • No definite volume, easily compresses or expands to fill the container it is placed in • Particles have the most movement and the most energy

Plasma • State of matter that has had the electrons stripped away • Particles move extremely fast – Fire is in the Plasma state – Glow around re-entry vehicles from space – The Sun

Discuss with a partner: • If you could be any state of matter, what state would you choose to be and why? ?

Phases of Matter

Phase Changes • Put the flow chart on page of your journal. • Label the sold, liquid, and gas phases on the flow chart.

• • • Monday, September 12 th Do Now: Look at your test score and open response answer and score. Make a note on your scantron sheet if you plan to retake the test or not. Separate your scantron sheet from your open response answer. We will be discussing the open response and you may take it with you if you plan to redo it. If not, you will be returning the scantron and open response answer to me.

• Today’s PLAN – Identify the observation, hypothesis, experiment, and conclusion component in a lab experiment. – Identify the variables in an experiment. – Analyze and interpret data tables and graphs. • Today’s DO – Correct/Complete your experimental design (1015 mins) – Conduct your experiment (10 mins) – Graph and conclusion (remaining time in class period)

Lab Expectations • Work with your group only. • Speak respectfully. • Treat each other and lab materials with respect. • Contribute positively at all times during the design process and experiment. • Do your part to help your group. • Clean up and return materials to their appropriate places when finished.

Tuesday, September 13 th Do Now: • Explain what you learned yesterday while doing your experiment. – What was the answer to the problem you tested? – Was your hypothesis correct or not. Explain. – If you did not finish and turn in your graph and conclusion, get them finished and turn them in now.

• Today’s PLAN – Describe energy transfers associated with phase changes – Describe the relationship between kinetic energy and the mass and speed of an object. – Describe the relationship between potential energy and the mass and position of an object. • Today’s DO – Complete Phase Changes flowchart – We will compare and contrast kinetic and potential energy. – We will practice calculating the kinetic and potential energy of objects.

Phase Changes • Vaporization: liquid to gas • energy absorbed (taken in) – Evaporation: happens at the surface – Boiling: happens at the surface and inside the liquid

Phase Changes • Condensation: gas to liquid – energy released

Phase Changes • Freezing: liquid to solid – energy released

Phase Changes • Melting: solid to liquid – energy absorbed

Phase Changes • Sublimation: solid to gas – energy absorbed – https: //www. youtube. com/watch? v=Ft 2 K gtl. P 8 Lk

Phase Changes • Deposition: gas to solid – energy released

Phase Changes 5. sublimation 2. Vaporization: Boiling or evaporation 1. melting 3. freezing 4. condensation 6. deposition 7. LOW ENERGY 8. HIGH ENERGY

Homework • For each phase change on your flowchart (1 -6), tell what states of matter are involved AND whether energy absorbed or released during each change. • QUIZ tomorrow over states of matter and phase changes
