Grade 6, Chapter 5 Investigation Organizer:

**1. Plan It**

** Research. ** Look up the definition of astronomical units in an encyclopedia.

- Use the encyclopedia to find the mean distances of the planets from the sun.
- Use division to write the distances of the planets from the sun in astronomical units.
- Decide on a scale for your diagram.

**Our planning completed**

**2. Put It Together**

** Construct your diagram. ** Use the scale to determine the distance of each planet from the sun on your diagram.

- Draw the sun at the edge of the paper. To find the position of Earth, measure the scale distance from the sun and mark the place.
- Use the same method to mark the placement of the other planets. Draw the planets and write each planet's name.
- Include the scale on your diagram.

**Our diagram completed**

**3. Wrap It Up**

**A. Create a brochure.** Your brochure should share what you have learned in this project. Include the distances of the planet from the sun.

**B. Write. ** Write a paragraph in your brochure to explain what an astronomical unit is and how it works for your diagram.

**Brochure completed**

**4. Discuss Your Results**

- Did you use astronomical units in your diagram?
- Did you use scale drawings?
- Is your brochure complete?
- Did your group work together and share ideas?
- Why did you use astronomical units in your diagram?

**Review completed**
