Introduce the energy graph depicting the total of energy changes which occur during an exothermic reaction.
Define and describe with examples of some typical exothermic reactions.
Point out on the graph the energy of the reactants, the activation energy, the activation complex, the heat of reaction, and the final energy of the products.
Show by overlapping graphs of various activation energies how that will affect the rate of the reaction.

Lesson Comments
Bobby came on line 15 minutes late, lost contact after 15 minutes, and was unavailable for the last 15 minutes.
In today's class, we discussed Avogadro's number and the mole, including what they are and how they are used in chemistry. We did practice problems involving the topic and Andrew asked lots of questions when he was confused and was very attentive during our work.
Review the processes involved in product formation.
Discuss the formation of an activated complex prior to to the formation of the final products of reaction
Define the activation energt
From an energy-progress diagram, indicate the reactant energy, the increase needed to reach the activated complex, the activation energy, the product energy, and the energy released by the reaction.
Discuss the biological function of lipids
Sketch and describe the structural formula of a fatty acid.
Indicate both saturated and unsaturated bonds
Sketch and describe the structural formula for a glycerol molecule
Indicate how a fatty acid can form a bond with the alcohol groups of the glycerol molecule.
Define this as a triglyceride
Discuss the biological and chemical uses of triglycerides
In today's class, we would have learned about avogadro's number, including what is it, how to use it, and why it is important. We would have also learned about electron configuration if time permitted, including what it is and how to apply it to chemistry.

Lesson Comments
Andrew came in late today and was only hear for five minutes of class. We will continue our discussion on Monday.
Outline and review the collision theory of chemical reactions.
Define the activation energy and the need for it before a reaction can occur.
Draw an energy v progress in time graph for a typical exothermic reaction.
Discuss the meaning of the main parts.
View an exothermic reaction energy graph from the internet and examine the activation energy.
View the formation of water by exploding hydrogen and oxygen gas.

Lesson Comments
This was on line. All drawings were done on a whiteboard. Bobby seemed to comprehend the energy and time requirements to arrive a the reaction rate.
Write a complete analysis lab of a protein using a word document.
Include the aim, material, procedures, observations, and what each observation indicated.
Based on the observed results, and the knowledge of what each reagent change means, arrive at a qualitative analysis of the elements which comprise a protein.

Lesson Comments
Sam could follow the lab results on line. With some review of reagent color changes, a list of elements was identifid
In today's class, we discussed mass number and atomic number, including what they are, where they are found on the periodic table, and what their purpose is. Andrew also learned about isotopes, including what they are and what function they serve in the world of chemistry. Andrew did very well and asked questions when he was unsure of something.
