Review several songs we have learned over the past couple of years: Happy Birthday, Sweet Home Alabama, The Lion Sleeps Tonight, and Somewhere Over the Rainbow.
Review all chords in the keys of C and G.
Review G major scale and chromatic scale exercises.
Craig did a great job, and I wish him the best of everything as he transitions into high school.
Craig and I went out to play some basketball today. We practiced shooting and dribbling. I reminded him of all the exercises we have learned together. We discussed how he can do those at home to continue his health journey.
UNIT 1 – MOTION AND ENERGY: Chapter 4 – Sound and Light
Lesson Outline
The Colors of Objects – We learned that the colors of an object depend on the wavelength of the light waves it reflects. When light waves of different wavelengths interact with an object, the object absorbs some light waves and reflects others. The wavelengths of light waves absorbed and reflected depend on the materials from which the object is made. When reflected light comes in contact with your eye, the cone cells in your retina send nerve signals to your brain. The color that an object appears to be depends in part on the color of the light shining on it. Then we learned that white light is a combination of light of many different colors.
Craig and I finished our book today! It was a great ending. Again, it referenced many governmental and geographical concepts. We also learned about the strange deaths of both Thomas Jefferson and John Adams on the same day - and it was July 4th, the 50th anniversary of the Declaration of Independence. We read the Epilogue and parts of the Afterward. We agree, a good book!
Craig completed an argumentative essay today. We reviewed the structure required for a basic academic composition. Craig did some research for this essay and documented two items in the essay: one paraphrase, one quote. We reviewed and executed MLA format on this essay.

Lesson Outline
Light and the Human Eye – We learned that the cornea is the first part of your eye that light rays travel through. It is a convex lens made of transparent tissue. The iris controls the amount of light entering the eye. The pupil is an opening that leads to the inside of your eye. In bright light the iris relaxes and the pupil becomes smaller. In dim light the iris contracts and the pupil becomes larger. Then we learned that behind the iris is the lens which is transparent tissue that helps focus an object. The back of the eye has a layer of light-sensitive cells called the retina on which images form. Rod cells in the retina fire when the levels of light are low. Cone cells in the retina fire when light levels are high. Three types of these cells are sensitive to different wavelengths of light allowing us to see colors. Then we answered questions identifying electromagnetic waves.
