Physics II Lesson 4 Work, Power and Energy
We have a preliminary definition of work as the vertical movement of a load, and we express it with a notation in foot-pounds. However, one never hears of a car with an engine that generates 5000 ft. lbs., one usually hears of the horsepower associated with an engine.
Physics II
This study builds upon the investigation of simple physics phenomena from the previous grade (Heat, Light, and Sound). Now we investigate electricity and magnetism, mechanics, acoustics, and optics. The approach is phenomenological, but the student will be led to learn some of the fundamental laws of physics such as the mathematical ratios of musical intervals, magnification and refraction, the electrical circuit, and the mechanical advantage of simple machines.
Writing/ Dictation Exercise VELVET SHOES by Elinor Wylie
Let us walk in the white snow In a soundless space; With footsteps quiet and slow At a tranquil pace, Under veils of white lace. I shall go shod in silk And you in wool, White as white cow’s milk More beautiful than the breast of a gull.
Wish Wonder Surprise – English Literature and Creative Writing
This book is useful for grades 7 through 10, for it is a study of literary genres that includes such stylistics as prose narrative, scientific descriptive narrative, poetry, oratory and speech-writing. Some of the finest representations of each genre are provided for study as the student is led towards his own creative expressions. Activities in illustrations support these creative writing lessons.
Cartesian Coordinates
In the study of perspective drawing, (Live Education, Perspective Drawing) we learned that a powerful tool was created through the implementation of the grid. It not only allowed for an exact representation of three-dimensional space on a flat surface, but could also be extended to map projections and the charting of the earth through latitude and longitude lines.
Introduction to Algebra
This approach to the teaching of this subject incorporates visual analogs for the understanding of beginning algebraic concepts. For example, negative numbers are seen as “below zero” on the thermometer, combining like terms operations are depicted as sorting similar products on store shelves, linear equations are seen as sea routes and avenues of transport between islands on a mythical land overlaid with an XY grid of Cartesian coordinates.
Lesson Activity Kalevala
Read excerpts from the Kalevala, Finland’s national epic (Land of Heroes — a Retelling of the Kalevala, by Ursula Synge, published by Atheneum Press, is a good student version to read). Write a description of one or more of the heroes or heroines in the main lesson book. Illustrate the narrative either with a drawing or water color painting.
European Geography
The student is introduced to the geographical features of the European continent — its rivers, mountains, and seas, as well as the flora and fauna of the diverse terrain. Most important to this study is a portrait of the diversity of the people and their way of life who inhabit the various countries that comprise the nations of Europe.
Perspective Drawing
Exact geometrical perspective drawing, using T-square and straight edge, was developed in the early Renaissance. Perspective geometry creates the illusion of seeing into three-dimensional space on the two-dimensional surface plane of the picture. The student will learn to construct architectural interiors and exteriors as well as landscapes. Embedded within this study are main lesson contents on Renaissance themes.
Perspective Drawing
The grid is easily constructed. Begin with the bottom baseline horizontal, and measure eight equal intervals of one inch apiece. Connect all of these to the vanishing point at the upper center of the drawing. Now draw the second horizontal. You will have to place it at a distance from the first horizontal that looks like a row of eight squares (not rectangles) across. Try to judge this accurately. Does the row look like square tiles or rectangular tiles. Make the necessary adjustment.
Lesson 12 The Grid
What we have just created through the division of a given space, is the grid. We have made a vertical grid, but we can also make a horizontal grid for ceilings and floors. The grid is fundamental in creating an accurate representation of three-dimensional space and for the accurate placement of figures in that created space. Consider the overlapping of objects that were studied in lesson 2.

Leonardo da Vinci
One of the contradictions in Leonardo’s nature was the fact that he had so gentle a disposition, even to the point of becoming a vegetarian so as not to inflict harm on animals, and yet at the same time he designed a number of horrific military machines. He was well-known as a military engineer and at one time was employed for this very purpose in Milan.
Leonardo da Vinci
It is well-known that Leonardo liked to find actual models for his drawings and paintings. In this regard, there is an interesting anecdotal tale that has the ring of romantic fiction, but one can imagine that it could have happened. It makes a strong impression on young people so it is valuable to include.
Renaissance Biographies
One lives through the exciting times of the European Renaissance through the lives of three principal biographies. Art history of the Renaissance is introduced in this study and one of the important activities of this book is devoted to learning portraiture.
