Friday, September 9th 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 Todays PLAN 1.1 Contrast matter and energy 1.2 Classify matter by phase and composition 1.3 Describe energy transfers associated with phase changes Todays 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 students teacher school Barren Middle homework

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.

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 and 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 12th

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. Todays 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. Todays DO Correct/Complete your experimental design (10-15 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 13th 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. Todays 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. Todays 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=F t2KgtlP8Lk Phase Changes Deposition: gas to solid

energy released Phase Changes 5. sublimation 1. melting 3. freezing 2.Vaporization:

Boiling or evaporation 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
