The Planets

1. Despite the proximity of the moon to Earth, the two bodies are glaringly dissimilar. The other three terrestrial planets bear some close similarities to either Earth or the moon. But each is unique. Each teaches us something about the others and about ourselves.

2. Mercury, Venus, and Mars are all close to Earth. However, they were long shrouded in mystery. Venus is covered with clouds that perpetually hide its surface. Mercury has no significant atmosphere. Its rocky surface is accessible, but it is so close to the sun that we can observe it effectively only in twilight. But our own murky atmosphere provides a poor view. Mars, however, with its surface markings and polar caps, appears intriguingly Earthlike.

3. However, before any physical analysis of the planets is possible, we need distances. The distances in AU between the bodies of the solar systems are found from their orbital locations. The distance in kilometers from Earth to any of these bodies then gives the number per AU (that is, the distance in kilometers between Earth and the sun) and thus the distances in kilometers between all the planets. In practice, we use Venus, measuring its distance from Earth in kilometers by radar (radio direction and range).

1. Which statement best expresses the main idea of the passage?

a. Earth and the moon are dissimilar.

b. Mercury, Venus, and Mars are close to Earth.

c. There is much to be learned about and from our three neighboring planets.

d. We need to know the distance of each planet from Earth.

2. Which of the following phrases most accurately identifies what this passage is about?

a. the dissimilarities of planets

b. the proximity of planets

c. the distance between planets

d. details of the planets

3. Which paragraph contains the central idea?

a. paragraph 3

b. paragraph 1

c. paragraph 2

d. none of the paragraphs

Choose five tone words from the following link that you would like to incorporate into your vocabulary this week. Write down those five words in your journal, with their definition, and a person/image/object that that word makes you think of! (scroll down to page 2 of the link)

Motivating Art Students

Most children need some form of stimulating motivation to achieve high-quality results in their studio art endeavors. It can be either visual or verbal. Students must have something to say if they are to give it visual form. The introductory phase of an art lesson should kindle the spark that ignites curiosity and piques interest. It is unfair to expect students to be challenged or excited by a teacher saying “Draw what you want today,” or “Paint the way you feel.” Some of the many successful ways to begin an art project include the following:

  • Showing visual materials on the theme selected
  • Viewing examples of previous work
  • Guiding a class discussion in recalling a past experience
  • Conducting a field trip to enrich the students’ knowledge of the subject selected
  • Playing recordings or tapes to create the mood of the particular visual theme
  • Demonstrating the technical process with student participation
  • Calling attention to a bulletin board or chalkboard presentation prepared for the project
  • Having a guest speak, perform, or model for the students
  • Using poems, stories, lyrics, and music as motivational enrichment”
