Review and analyze the procedure used to determine the % yield of product due to a reaction. Discuss the steps which can be used. Introduce titration as a method of chemical analysis. Explain the use of a burette. Elicit how this method can be used to accurately determine the concentration of an acid(or. base), based on the molarity of either one and the volume needed to reach the equivalence point.

The procedures and mathematics of titrations will be continued at the next class and then examined as a lab.
Review acceleration formula which relates velocity to time and acceleration of gravity. Review formula to determine distance in free fall. Examine the relationship which exists between force, mass, and acceleration. Discuss the effect of area and force on pressure exerted. Explain free fall using the relationship between force and mass. As mass increases during free fall, the acceleration remains the same, 9.8 msl^2.
The concepts used in curve sketching will be reviewed. These include intercepts, symmetry, asymptote's, limits at infinity, continuity, differentiability, extrema, concavity, and inflection points. Examples will be done to put everything we know together to sketch a graph. Technology will be used to verify the result when possible.

We took advantage of extra time today to complete several of these time consuming problems.This was a challenging session. We continue to make good progress in the study of calculus.
Unit 4- Short Fiction II/function of character, setting ,and structure
Lesson Outline
Today's lesson addressed writing an interpretative essay for the AP exam. I had assigned Faulkner's story "A Rose for Emily" along with an AP style prompt for Joshua's homework. As he continues to struggle with an interpretative analysis , on the board I outlined areas for guidance. First, we examined Emily's life chronologically, then as narrated . Based on narrative structure we then discussed the purpose of the structure as well as the story's theme about the past . I further noted how the metaphorical portions of the text relate to plot structure , theme , and the narrator's complex perspective of the past and Emily. Based on class discussion , I have assigned the essay on the text as homework.
Unit 4- Short Fiction II/function of character, setting ,and structure
Lesson Outline
As Joshua is still struggling with the analytical essays, during the first segment we reviewed his homework essay on The Great Gatsby. I provided suggestions on forming a claim by incorporating descriptive verbs such as " conveys, informs, and elucidates" and on incorporating adjectives into the claim when discussing characterization : for example the "symbol x conveys Gatsby's idealism and longing for the unachievable." I further placed sample topic sentences on the board and discussed how his essay homework did not tie any of the cited symbols to a character trait. We then reviewed the MCQ homework where Joshua needed assistance. I demonstrated how to analyze the passages and how to examine the nuanced answers to the multiple choice questions.
Define theoretical and actual yield of product formed in a reaction. Discuss reasons why the theoretical yield is usually not equal to the actual . Introduce the formula for calculating % yield. Work from a reaction to produce aspirin from acetyl anhydride. Determine the percent yield or product from a given amount of reactant.
Describe acceleration in terms of velocity change and time and how rapidly velocity changes. Examine unbalanced forces, equilibrium, constant velocity, and acceleration. Determine how acceleration is directly proportional to the net force. Based on a graph, show how acceleration is inversely proportional to the mass. State Newton's 1st law both in written terms and by formula.
Solve problems using all 3 arrangements of the law.
We will do a review problem involving increasing and decreasing functions. We will then use the second derivative to determine where a function is concave upward or downward and to find inflection points. Examples will then be done using these new concepts.

The class outline was completed. We are ready to put everything together to analyze the graph of a function using calculus.
Use demo materials to elicit the formula relating pressure, force and area. P=F/ A. Determine that Newtons/meters square are referred to as Pascals. Discuss friction as a force, include air resistance as friction. Define free force. Discuss the acceleration due to free fall, label it g and define it as the force/mass. Elicit how g is the same regardless of the mass used in free fall.
Work on stoichiometric problems solving for products formed from given amounts of reactants, and mass of reactants needed to produce a given. amount of reactant. Solve problems to determine the limiting reactant in a reaction, the mass of the limiting reactant.
