Joshua was instructed to open his project file and we worked together to create the yellow, orange, and purple ring of the design.

Joshua and I continued on the arrow portion of the design.

I had Joshua open his project file and we worked together to create the crown shapes in his design.

Example of volumes of revelation using washers and shells were presented. We also looked at volumes using cross-sections of a solid. One example led us to a discussion of hyperbolic functions and catenary curves.

conversation about weekend / general topics

worked on exercises relating to the Easy German Video we watched last week.

Define the pitch of a sound as being a function of the frequency of the sound wave. Indicate how the thickness of the vibrating body will change the frequency of the sound and thereby the pitch. Discuss the infrasonic and ultrasonic parameters of sound waves as received by various species.
Discuss the speed of sound changing with the media and the temperature of the media. Define intensity and soundness of sound, discuss the objective and subjective involvement of sound. Introduce decibels as the intrinsic objective measurement.

As Joshua encountered some difficulty in yesterday's poetry analysis test, today we first reviewed the poem . I explained the poem's somewhat cryptic exploration of the l connection between the material and the spiritual world, and the relationship of that connection to God's eternity. I then introduced our next unit, long fiction, by on the board outlining the elements of character: bias, values ,and motivation. I further addressed how characters can be representative of cultural values which may be in conflict with the individual's values. I defined "ethos" and zeitgeist " in the context of conflicts between the individual and society.

We will have a problem solving session involving volumes of revolution. We will use the disk method to solve the problems.

Define ionization energy in terms of electron removal from an atom. Discuss energy requirement in order to remove an electron from a valence orbital. Use tables to show ionization energy changes in groups and periods, explain why. Outline magnesium ionization energies,.Explain why only the valence electrons are removed to form an ion and not the core electrons

Use diagram and charts to define and explain the Doppler effect. Determine that the effect is caused by a change in the wave length as a sound approaches and leaves an observe. Discuss how the change in pitch is caused by a change in the wavelength. Using running forks and diagrams, explain how a sound wave is a series of compressions and rarefactions of air molecules. Discuss pitch change corresponding to string diameter. Indicate the maximum and minimum Hertz heard by certain animals
