Teacher: Ben Thurman Subject: Chemistry Preliminary Planning SOL#: CH 2h, 5a,c Liberty High School Daily Plan Dates Taught: September 12 Topic: Chemical/Physical Properties/Matter OBJECTIVE: TSW Classify chemical/physical changes and properties Distinguish between elements, compounds, and mixtures Recall Concepts of Dimensional Analysis, Metric System, and Significant Digits Materials Needed: (Include all pre-class preparation.) Water, Beaker, Hot Plate Food Coloring Baking Soda, Vinegar, KMnO4, Glycerin WS – Physical/Chemical Properties, Changes and Classification of Matter Classification of Matter Puzzle Classroom Set of Burner Labs and Burners Homework: (How do you plan to reinforce the learning?) Test Corrections In Class Lesson Opener: Molecular Movement Demo: Hot Water/Cold Water - Food Coloring Demo to demonstrate molecular movement Lesson Presentation /Activities: Return Tests – go over any questions, Review test correction policy (CHEM) Pre-AP – Finish Lab From #8 Analysis States of Matter Inquiry Activity Comp Book – Physical vs. Chemical Properties (USE TEXTBOOK pg15-19) - Physical Properties – Describe the substance itself: state, color, odor, volume, density, melting point, boiling point - Examples: student hair color, eye color - Chemical Properties – properties that refer to a substance’s ability to change into another substance (Think Reaction) - Example: The ability of iron to react with oxygen (rusting) Comp Book: Double Bubble Map - Physical Changes vs. Chemical Changes Physical o Do not produce a new substance – just the same as before, Can be easily reversed o Examples: Phase changes, tearing paper, dissolving salt in water Chemical Changes o Produces a new substance – something new, different is formed o Cannot be easily reversed o Characteristics: light, heat (energy), color change, gas production, odor, sound, formation of precipitate o Cooking anything, Burning paper, Sodium Hydrogen Carbonate/Acetic Acid Examples (think-pair-share) o Cooking Scrambled Eggs - Chemical o Breaking glass - Physical o Lighting a candle - Chemical o Steam from you shower condenses on the mirror – Physical o Comp Book: Tree Map – Classification of Matter Puzzle - Students work puzzle as a group, copy into notebooks - Each group presents a section on the board o Worksheet o Burner Lab as time allows Closure: KMnO4 and Glycerin Reaction Exit Slip: Cite evidence of a Chemical Change Lesson Reflection
