Present and discuss the historical development of nuclear fission, starting with Fermi in 1934 and working up to production of nuclear bombs. Define fission in terms of nuclear division into 2 fragments with a resulting release of energy. Show and discuss images to highlight how the nucleus elongates and then divides. Uranium will divide into barium and krypton, with a release of energy equal to 7 times that of TNT/ atom. Present and discuss the formula for fission of uranium-235.
Review and analyze the homework questions from Wed.
Define, discuss and present examples of amine aromatic hydrocarbons. Discus how they are chemically related to an ammonia molecule, in which one hydrogen in ammonia is replaced by a hydrocarbon group. The general formula becomes R-NH2. Explain primary, secondary and tertiary amines. Discuss nomenclature using examples. Present puitricine, cadaverine, and aniline as examples to demonstrate properties. Review and discuss homework questions from Thursday.
We completed a review and analysis of the MCQs on AP Practice test 3. Joshua did very well. We addressed the questions where Joshua was unsure how to derive the correct answer by practicing process of elimination strategies . Additionally we stressed the importance of paying close attention to the question in order to determine if the question seeks an inference or a more literal answer. . Last, we studied the Shakespeare sonnet that was on the practice test and reviewed the structure of the Elizabethan sonnet noting how the final couplet often resolves the question or problem raised in the first stanzas.
Discuss the general formula for aldehydes and ketones. Present a few common aldehydes and structural formulas. Include formaldehyde used in preservation, oil of almond, vanillin, and cinnamaldehyde. ketones would include acetone as the primary ketone (nail polish remover). Determine the IUPAC name for each example.
We reviewed Joshua's practice test essay analyzing a poem. We discussed how to implant critical AP words such as complex and perspective and then addressed how to incorporate certain images into the essay in order to avoid the essay appearing to summarize the poem. We then worked on tying these images into the claim. Overall, Joshua 's essay was very good and demonstrated his grasp of AP curriculum .
Outline the difference between alcohol and ether functional groups. From sample formulas demonstrate that ether molecules are created from an alcohol hydrocarbon substitution on the hydroxyl hydrogen. Present nomenclature through examples. Discuss uses of ethers as solvents and in medicine. Introduce halogenated ether molecules which are safer to administer than the traditional diethyl ether molecules. Note boiling point differences between alcohols and ethers, due to one small atomic change.
We continued to use the example problems in the text that are similar to those on the AP test. We also reviewed a related rates problem and an optimization problem. We will complete the derivative review if time allows.

Lesson Comments
We are almost finished reviewing derivatives. We completed the related rates problem and the optimization problem.
Today we reviewed the MCQs for practice test #2. We analyzed a difficult poem by Donne as well as a complex passage by Henry Adams. I provided explanations for questions where Joshua had difficulty ,,mostly by directing him to pay close attention to the language of the answers and by demonstrating how the correct response is often in the lines just above or below the cited lines. We discussed the AP's technical interpretation of symbols in the answers .
