## Physics Week 30

Class: Physics

Date: 3/31 **Move to 4/4

 Unit: Light and Reflection Topic: Introduction Lesson Objective: Students will complete the discovery lab. Materials: Lab instructions, various lab equipment State Frameworks: WO.10.P.1 Calculate the frequency and wavelength of electromagnetic radiation WO.10.P.2 Apply the law of reflection for flat mirrors: θ in = θ out WO.10.P.3 Describe the images formed by flat mirrors NGSS P-PS4-1AR Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, speed, and energy of waves traveling in various media. [Clarification Statement: Emphasis is on the dependence of wave speed upon media properties and the proportionality between the quantities (frequency and speed, wavelength and speed, frequency and wavelength, energy and wavelength).] P-PS4-3AR Develop and use models to describe the interaction of light with matter. [Clarification Statement: Emphasis is on both geometric (ray diagrams) and algebraic models (mirror and thin lens equation, Snell's law).] CCSS: RST.11-12.3 Follow precisely a complex multistep procedure when carrying out experiments, taking measurements, or performing technical tasks; analyze the specific results based on explanations in the text. WHST.11-12.4 Produce clear and coherent writing in which the development, organization, and style are appropriate to task, purpose, and audience ACT Aspire PLD: Translate moderately complex information into a table, graph, or diagram. Compare data from two or more simple data presentations (e.g. compare a value in a table to a value in a graph or categorize data from a table using a scale from another table). Predict the results of an additional trial or measurement in a moderately complex experiment. Evaluate the design or methods of a simple experiment (e.g. possible flaws or inconsistencies; precision and accuracy issues). Determine which hypothesis, prediction, or conclusion is, or is not, consistent with a moderately complex data presentation or piece of information in text. Identify implications and assumptions in a complex theoretical model. Science & Engineering Practices (SEP): Using Mathematics and Computational Thinking, Developing and Using Models Crosscutting Concepts (CCC): Patterns, Patterns, Structure and Function Disciplinary Core Ideas (DCI): PS4.A: Wave Properties Engagement: Opening Task: “Read your lab directions.” Discuss student questions before starting.   10 min Explore: Students will complete the discovery lab.   80 min Explain: NA Elaborate: NA Evaluate: Formative as students work. Material/Lab Safety: Basic lab safety rules

 Unit: Light and Reflection Topic: Characteristics of Light Lesson Objective: Students will identify the properties of electromagnetic radiation (light). Materials: Prism, laser, flashlight State Frameworks: WO.10.P.1 Calculate the frequency and wavelength of electromagnetic radiation WO.10.P.2 Apply the law of reflection for flat mirrors: θ in = θ out WO.10.P.3 Describe the images formed by flat mirrors NGSS P-PS4-1AR Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, speed, and energy of waves traveling in various media.

Pass a laser through as well to show that it does not disperse.   20 min Explain: Discuss the basic characteristics of light.   30 min Elaborate: Students will complete the assigned practice problems.   35 min Evaluate: Formative while students work. Material/Lab Safety: Basic lab safety.
