Sketch the structural formula for a generalized amino acid, describe the amino portion and the acid portion.
Define amino acids as also being called mono-peptides.
Show a diagram image of a typical amino acid
Define a protein as a polypeptide
Show, using the whiteboard, the dehydration synthesis which form a dipeptide, then a tri peptide and finally a polypeptide.
Define peptide bond
Discuss how the collision theory is involved in the progression of a chemical reaction.
Atom and/or ions must collide together in order to react to form a product.
Use a series of whiteboard drawings and images to show exactly what must occur before and during a chemical reaction.
Demonstrate by using the example of CO reacting with NO2 to produce CO2 and NO
In today's class, Andrew worked on an activity that covers symbols and trends on the periodic table, in addition to covering how to write and interpret chemical formulas. Andrew did very well with the activity and proved knowledgeable on the subject.
Calculate the reaction rate of a given specific reaction.
The reaction is CO + NIO2 yields CO2 + NO.
The concentration of the product NO is given, along with the starting and finishing time.
All symbols and calculations are reviewed.

Lesson Comments
Answer was determined using a step wise series of calculations
Dehydration synthesis to form di and tri saccharides, demonstrate using printed structural formulas
List and view the structural formulas of some common mono saccharides.
View the structure of and the synthesis of sucrose, or table sugar.
In today's class, we did an experiment where we used a cabbage-based indicator to test the pH of different substances we had on hand, including orange juice, baking soda, coca cola, and bleach. We discussed how pH plays a role in everyday chemistry and biology.
Discuss the term rate, and use everyday examples to indicate that a rate involves a quantity and a time.
Discuss rate as the change of quantity with time change.
Show how to mathematically determine the change in both.
Write a math. formula in symbols to use when determining the rate.
View examples of fast reactions and slow reactions.
Define reactants and products.
Introduction to biochemistry.
Discuss the 3 major biological chemical groups, carbohydrates, proteins, and lipids
Discuss carbohydrates, starting with starches.
Define carbohydrates, examine starches chemically, and examine the monomer unit, the monosaccharide, from which starches are synthesized.
