Introduce conservation of momentum . Discuss the effects of a small mass with a large velocity compared to a large mass with. a small velocity. Elicit the law of conservation of momentum and write a math expression to represent it. Discuss elastic collisions. Represent how the momentum prior to a collision is equal to the the total momentum after collision. Represent using model cars moving.

Today we will do example problems involving definite integrals. We will use the Fundamental Theorem of Calculus, the Mean Value Theorem for Integrals, and the Average Value of a function.

We continue to study and develop Joshua's interpretative and essay writing skills using AP essay prompts and text passages.. Today, we studied Joshua's thesis and opening paragraph and discussed how to form an interpretative thesis and to create a line of reasoning in the first paragraph. As I discussed some of the critical areas of the given text passage, we explored how the text suggests a conflict between the two characters arising out of the tension between family allegiance and a societal code of honor . We further discussed what evidence in the passage might support this interpretation. Joshua will complete the essay for homework.

Define and discuss spontaneous reactions, which occur without outside interference. Determine that they occur only in the direction that leads to equilibrium . Show examples of spontaneous reactions and elicits that they are all exothermic . Change in heat energy is negative. List and discuss. Few reactions occur spontaneously, but possess a positive heat of reaction. Use melting of ice when left in a beaker sitting on a table top. Elicit what occurs when a beaker of cold water is left sitting out. Define which way the heat energy moves. Discuss the energy transfer as heat is from hot to cold, from surrounding to system.

Discuss f x t impulse.Discuss change in mass equals momentum. Demonstrate how a force extended over a an increase in time results is a change in momentum. Explain why rolling a car into a haystack will result in a force generated over a longer time period resulting in a longer distribution of momentum. A change in impulse will occur when the time is extended which allows the momentum to come to zero over an extended time.

We continued instruction on writing an AP style interpretative essay by first reviewing my comments on Joshua's essay on "The Worn Path." We addressed tying the thesis to the focus of the essay question and reorganizing one paragraph for cohesion. In order to continue giving Joshua practice in this skill, I then posted on AP classroom another essay prompt and passage which we reviewed . I provided some direction for an analysis to assist Joshua in drafting a first paragraph that identifies an interpretative thesis and literary elements that support the thesis.

We will go over the assigned problems in section 4.3, We will discuss the Fundamental Theorem of Calculus, The Mean Value theory for integrals, the Second Fundamental Theorem of Calculus and the average value of a function.

This lesson was designed to complete the AP chemistry unit. The summary written for AP Chemistry continues into the physics period.

Describe how enthalpy changes accompany chemical reactions. Discuss the standard enthalpy change delta H. Define and explain delta rH and the subscript r. Define standard state as the most stable form in the system. Explain "per mole-rxn" Show examples of heat of formation reaction and note the change due to coefficients in the written equation. State general features for the heat of reaction, both exothermic and endothermic. Work on two examples designed to show how to calculate the energy of the reaction using an endothermic and an exothermic reaction

We will review the estimating of areas using Riemann Sums, the midpoint method, and the trapezoidal method. We will use the limit as the number of rectangles used for our estimates approaches infinity to find the exact area. The definite integral is the exact area. We will do a few example problems.
