Weekly Reader Connections

Teacher Guide: Lesson 22.3

The Weekly Reader Connections feature provides children with additional information about the topics that appear in the Curriculum Connection feature in their student books.

The article “The Solar System” presents children with a diagram that shows the Sun and the relative positions of the nine planets that surround it. Moons, comets, and asteroids are all part of the solar system in addition to the Sun and its planets.

After children read the article, have them do the Word Wise activity. Encourage them to use their imaginations as they write about their trips. Have any children who are unable to do the writing make a drawing instead. Suggest that they use words from the Word Wise Word Box to label parts of the drawing.

In preparation for the Data Hunt activity, make sure children understand that the planets do not stay still in the sky. Each one takes a while to move completely around the Sun in a path, or orbit. It takes Earth, for example, 365 days, or 1 year, to move all the way around the Sun.

If time allows, you may wish to share this data with the class:

  • Planet Earth differs from other planets in our solar system in many ways. Scientists believe that Earth is the only planet to have water and an atmosphere. They think there cannot be life on other planets without water and an atmosphere.
  • The planets are all different sizes, shapes, and colors. The order of their distance from the Sun, from closest to farthest, is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.
