Define and discuss pure substance. Use examples of different forms of sodium chloride all being pure substances.. View microphotograph of the faces of salt crystals.
Question different combinations and elicit if they are pure or not, by definition.
Discuss the term substance. Define it using homogenous and definite chemical composition. Explain the term "pure substance"
Determine from the definition whether listed substances are pure.
Explain precise and non precise definitions, use examples. Begin the study of states of matter and phases.
From examples, define the definition of a phase. Introduce homogenous and physical boundaries.
Hand out pre printed examples of each.
Hands on lab involving observation of chemical changes. The lab involved the production of hydrogen gas using zinc and hydrochloric acid. All observations, including color, state, observed changes and possible reactions were undertaken.
The second class dealt with the definition of states or matter, phases, and how to define them.

Lesson Comments
Ben did well in the lab. He is still overly tired, and appears to lose concentration at times. This seems a little more prevalent than in previous years.
Continue with the international system of measurement adapted in 1960, the SI. Outline the SI units for mass, length, volume (both solid and liquid), time, force, and energy. Use examples to illustrate each of the measurement, with some conversion into the American units. From the units for force and energy outline the use of Newtons, Joules, calories, and Calories.
Solve problems involving the release of energy by the conversion of mass into energy.
Contain with SI measurement and official units. Discuss the prefixes kilo, centi, and milli, which were assigned for HW.Discuss kelvin temperature, absolute zero, molecular motion upon cooling and conversion of centigrade into Kelvin.

Ben did not do the assignment issued on Monday, which is my day to assign HW for Ben. He did it in class with no problem. He could have easily done it at home. I will be working with him to improve.
Discuss the composition of the universe into matter and radiant energy. Elicit the older definitions of matter and energy and relate how through the equation of Einstein, the newer meanings are more relevant. Discuss how mass and energy and two sides of the same coin and related by E= MC^2. Indicate how if mass can be converted into energy, then energy can be converted in mass. Discuss the bending of light energy by gravity.

I was asked to sit with Joshua and discuss some aspects of the Honors course. His participation will be decided today.
Define and describe the SI units of measurement. List the quantity(type) of measurement and the base unit for time, lenght, mass, temperature and substance amount. These involve the second, meter, kilogram, degree kelvin, and the mole.
Discuss the difference between quantitative and qualitative measurement, and use hot and cold as quantitative and exact degrees and qualitative.

Lesson Comments
Ben had his spiral notebook and he was required to copy the information written on the board into his notebook. He is more than capable to copy from the board into his notes.
I am still concerned about his being overly lethargic in class, he is usually more upbeat and happy.
Lab exercise which is designed for the student to use observational skills.
Lab involves accurate measurements of mass, candle burning, products formed from the combustion, analysis of the loss of mass and production of radiant energy and smoke.
Period 1, lab exercise to practice observing skills, recording observations and drawing inferences. the lab involves the use of a detergent when placed using a toothpick into water, milk, and milk with food coloring. Student will observe and record observations.
Second period involves classwork which involves how the earth is protected from harmful uvb radiant energy through the chemical reaction of oxygen molecules being separated into oxygen atom and then recombining with oxygen molecules to form ozone. Each of the chemical equations are written out in symbol form and explained.
View and discuss the life of Nicolai Tesla, his accomplishments, his failures, and his ideas.
Discuss how his inventions, ideas, and thoughts have influenced and changed modern scientific thought.
