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.
