Lesson Comments
Today we started a new unit that addresses the changes over generations in the topics mentioned above. We started with a comparison between long ago and today in all of these areas.
Define and discuss the function of a catalyst in a chemical reaction. Show an example of the conversion of cis-2-butene into trans-2-butene using a halogen atom. Show step by step how the catalyst is involved in speeding up the chemical reaction. Use print outs to aid the demonstration. Also discuss the effect of ozone on the environment. Determine how oxygen is converted to ozone by halogen carbonates. Discuss the harmful effects of UV radiation on skin and eyes caused by decreases in the ozone layer concentration due to chemicals like freon. Show how the freon decreases the ozone layer by catalyzing the decomposition reaction.
View and discuss video which concentrates on the determination of voltage, resistance, current, and power through both series and parallel circuits. The math required to determine each of the factors is analyzed and the results compared. The differences in resistance, current, power and voltage is shown for each circuit type
For our introductory session on the play ,Hamlet, we first examined Aristotle's traditional framework for tragedy: a noble character, a flaw or hamartia, a reversal of fortune or peripeteia , and last catharsis. We then reviewed the distinction between an aside and a soliloquy as well as the historical basis for the story of Hamlet. Last, we discussed the purpose of a foil . I identified the three foil characters and discussed how the foil characters act as contrasts to the protagonist thus elucidating character.
Define and discuss activation energy. Relate it to the minimum energy needed to react. Discuss the effects on the rate of reaction when activation energy is low and when it is high. Use example of Nitrogen dioxide combing with carbon monoxide to form nitrogen monoxide and carbon dioxide. View and analyze the reaction rate graph. Define on the graph the transition states, the activation energy and the heat of reaction. Show the difference between an endothemic and exothermic reaction graph.
lab exercises which demonstrate Ohm's law. How are voltage, current, and resistance related to one another. Exercise involves measurements of voltage and current using bulb resistors of varying resistance. Measurement are conducted by varying the voltage passing through a number of bulbs in series and measuring the current. Resistance is determined by using Ohm's law, and compared to each set of resisors
