Lesson Comments
During today's ACT session on Math practice, I demonstrated to Ben the method of graphing the Standard Form of linear equations and comparing with the Slope Intercept Form. He was very receptive and this is an essential ACT math skill.
Discuss reaction of zinc and hydrochloric acid to produce a gaseous product. Determine that it involves both a physical and chemical change. The physical change was the change of the solid zinc a soluble solute, and the chemical change involved the production of a gaseous product, hydrogen. Discuss some physical and chemical reactions, like the electrolysis of salt to produce a soft metal and a green gas. Write the formulas for sodium chloride solution reacting with silver nitrate solution to produce the photographic precipitate silver chloride which is used in the manufacturing of film.
We learned about conditional statements in Python. Then we learned how to interpret Boolean data types. Next, we practiced using the integer data type with the modulo operation to find if there is a remainder. We learned how to use conditional statements in a program.

Review definitions of molar mass, density and square root determination using a calculator, Define the rate of diffusion of gases as the being inversely proportional to the square root of the molar mass of the gases. Write the formula. Determine that a gas which is 4 times the molar mass of a second gas would diffuse through a pinhole at 1/2 the rate. Use an example of hydrogen gas and oxygen gas in a container. Determine that the hydrogen molecules would diffuse 4X faster than the oxygen molecules.
Begin discussion on chemical and physical changes in matter using Zn and HCl as examples.
Ben and I discussed paraphrasing as saying it in your own words while keeping the same meaning. Ben read over the examples. Next, we worked on advanced grammar including verb tense, parallelism, punctuation, conjunctions, and word choice.
We practiced sketching and writing equations of a line given 2 points. Then we used the point-slope form of a line to graph the line.

Lesson Comments
During today's Math ACT practice test questions, Ben was receptive to trying these useful exercises. We covered important/common problems such as functions, inequalities, and word problems and Ben became a bit tired after nearly 20 minutes of practicing. He will need additional stamina/endurance to achieve the high ACT Math score he is capable of.
