To describe and explain the major types of solutions based on the solvent used. The most common solution utilizes water as the solvent. These are classed as aqueous solution. I will discuss the common solvents which are soluble in water. Alcoholic solutions will be discussed next, with the common solutes used and the reason for this solvent's use. We discussed the classification of alcoholic solutions into elixirs, tinctures and alcoholic solutions based on the concentration of alcohol in the solution.
Examples of gaseous solutions and solid solutions will be discussed. Examples of each type of solution will be listed and briefly discussed. A solution of oxygen or carbon dioxide in water to produce seltzer, or a solution of alcohol in water to explain and describe the term miscible... We will discuss the most common solution which will be solids dissolved in liquids and the choice of solvent for common solutes. The final type of solution will be solid solutions, with the solvent being a solid, like mercury in gold to form an amalgam, or water dissolved in sugar to form a moist solid, or carbon dissolved in iron to form steel.

In an attempt to finally arrive at a course which will be best suited for Sam, I discussed the possibility of a course which will concentrate on drugs and chemicals affected the nervous system. this will involve an in depth study of the nervous system, nerves, receptors, and responses, as well as contraindications. I need a final decision from Sam
Informed Samantha that the type of solution is based on the solvent. We will then discuss the most common solvents for compounding a solution and that the solution is named based on the solvent. They will be aqueous, alcoholic,tinctures,solid, and gaseous solutions. The degree of solubility of the solute will also determine the solvent needed. Solutions which are going to be applied externally will require solvents which are compatible with the ph of the skin and are hydrophyllic.

Samantha was not present for the class. I also will discuss with her the possibility of a course in the pharmacology of nervous system altering drugs. She discussed that she was very interested in that area. I will speak with her and outline to her that this will involve the anatomy and physiology of the nervous system. It will involve the anatomy and physiology neurons and especially the organ called the brain. It will be a fairly complex investigation of the brain, nervous system, normal and abnormal chemical effects as well as the chemistry of different classes of these compounds
This is the first lesson of the integrated course I am developing for Sam.
Discuss the terms mixture, pure substance, homogenous, solute, solvent.
Relate to lotions for external use and some internal ingestion

Sam had a bottle of Snapple on her desk which became a good starting point. She read the ingredients on the label and we discussed the states of matter in which those ingredients existed.
Using the physical appearance of the snapple, a definition of a homogenous solution was arrived, along with the terms solute and solvent. The different forms of solutes was discussed, along with the use of specific solvents for a specific purpose, like dissolving urea in oils for use on dry skin.
Outline a course of study to meet her interests and requirements
Lesson Outline
Discuss what Sams' interests are in science and how best to obtain a meaningful outcome which will incorporate scientific and practical concepts.

I was able to meet with Sam at 1:30.
After discussing with her what she would like to achieve, I outlined the beginning of a course which I thought would accomplish both our objectives. It would involve basic chemical principles, inorganic compounds and organic compounds of importance and the production of solutions and suspensions and emulsions which are used in cosmetics and medicinals.
Sam was present for only 20 minutes of the scheduled 120 minutes. I wanted to determine the extent of her physics instruction and where her interests lie in science. Using what information I could obtain, and working with Sam, I wanted to outline a course of study she could work with for the remaining year.

I finally was able to speak with Sam for a short period of time to try and elicit her interests and physics capability. She seems very capable, but her interest may lie outside the realm of physics. I am going to work up a course which will include the physics necessary, along with, perhaps, an integration of physics into her academic interests.
