We continued to study the author's literary style of telling " a true war story" that is fictionalized. On the board , I first reviewed the purpose of the author's style- to make the reader feel what he felt ,not what the author experienced in reality. We then studied the next chapter and explored how the author elaborates on the function of writing- for him to objectify his experiences so that he can face them. This explanation dovetails to our discussion yesterday of why the author switches the point of view to the third person in certain passages. Next, we read together the chapter entitled"Form" wherein the author distinguishes "story truth" from "actual truth or historical truth." We discussed how and why fiction or story truth can capture what historical truth can not. Last, we addressed how the paradoxes of war mirror the paradoxes of fiction. Joshua tonight is rewriting a paragraph identifying the paradoxes of war-beauty and destruction- referenced in the novel

Today, Joshua watched daily video 2.4 on the AP Classroom site which covered Roles and Powers of the President. We also reviewed the last lesson on Congressional Behavior.

Correct homework problems. Convert moles to mass formulation.
Examine how to determine the molar mass of a compound and solve some problems from the text. Convert moles of a compound to mass. Discuss empirical and molecular formulas. Discuss percent composition of elements in a compound, and how to determine the percent compostion. Work a few problems converting elements in a compound to percent composition of those elements based on moles.

From the paradoxes of fiction to the paradoxes of war, we today explored the author's imagery of war as both devastatingly ugly, yet juxtaposed with the beautiful. We further discussed how last night's reading shifts the point of view from the first to third person and the function of the point of view shift. Additionally, we addressed the irony and implications of the story's plot of a returning veteran who faces a Fourth of July stateside where no-one cares to listen to his "war stories" despite his service . We noted the symbolism in the veteran's driving in circles around a lake and watching fireworks reminiscent of wartime flares and battles. I last provided guidance on how to incorporate today's discussion into tonight's writing assignment.

Began working on quiz material for AP Pre-calculus.

Today we began in AP Classroom by going through his homework. Joshua had difficulty with one problem. We looked up a video on AP Classroom to help clarify the concept of Log scales. Then we went back to the problem and tried it. It was a problem regarding Richter-scale and Earthquakes. It was difficult, but we were able to work through it together. Then we started a new lesson 2.12 Properties of Logarithms. We practiced expanding and condensing logs, changing the base, and evaluating logs. These are kind of like a puzzle piece to figure out. Joshua did well with this.

Solve problems converting moles to particles and particles to moles. Discuss the molar mass meaning and how to calculate the MM. Graph the mass of an atom vs the mol, then calculate the slope to determine the molar mass and gram molecular mass and the atomic mass in AMU.

We examined thematic and stylistic similarities between a chapter in the novel and Hemingway's A Farewell to Arms and Conrad's "Heart of Darkness." First, we discussed how O'Brien and Hemingway both use a simple syntax and detached tone. Thematically, we next studied the story "The Sweetheart of Tra Bong" . We addressed how Hemingway wants the reader to see and to hear the experience of war whereas O 'Brien wants the reader to feel what Viet Nam FELT like, thus the injection of the imaginative elements,. We further delved into how Mary Ann is a character like Kurtz in Heart of Darkness:both become a part of the jungle and abandon the morals and standards of civilian society. We discussed what living on the verge of death does to the soldiers and why that experience ultimately estranges them from civilians who have not experienced war.
