__**Lesson Plan #1:**__ Topic(s) - Functions from Data Grade Level - Precalculus (Algebra 2) - 10-12

Video || This lesson begins with a short attention grabbing video of a weather report. Students will spend some time finding latitudes and high temps of cities in US. They will create a scatter plot of this data on a graph. || Fermentation in a Bag Activity Mini-Fermenter || An activity called Fermentation in a Bag which allows for the fermentation of yeast, sugar and/or cornmeal will be done. A Mini Fermenter will be created which will help determine amounts of gas produced. Regression equations for this data will be produced. ||
 * 5Es || Link || Description ||
 * Engage || Teacher Notes
 * Explore || Teacher Notes || Students will then explore the main types of functions finding names, drawings, and equation forms. ||
 * Explain || Teacher Notes || Students will draw in a line of best fit and determine the linear equation for the latitude/temp scatter plot. Graphing calculator utilities will be used to create scatterplots, determine best regression equations (not necessarily linear). Correlation coefficients may be used. ||
 * Elaborate || Teacher Notes
 * Evaluate || Teacher Notes || Piecewise functions and function values that do not make sense in the scenario may be discussed. ||



__**Lesson Plan #2:**__ Topic(s) - Law of Sines and Law of Cosines Grade Level - 10-12

Video - not in a vacuum Video - air resistance || Falling objects in and out of a vacuum are watched and discussed. The concept of air resistance is watched and discussed. || Law of Cosines Lesson || Law of Sines and Cosines are explored and developed using previous knowledge (solving right triangles and the Pythagorean Theorem). The Ambiguous Case is explored. || || PowerPoints are used to further explain the Law of Sines and Law of Cosines. || || Activity involving airfoil design for semi-trucks is used. It is extended to involve materials choice and costs. || || A worksheet with problems involving choosing the appropriate law and then solving problems using the Laws. Challenge problems are included. A key is included. ||
