After reading The Sun, Earth, and Moon, students will have a good understanding of the following: why we have night and day, why we have seasons, what causes high and low tides, and what is happening during solar and lunar eclipses. The text is supported by informative diagrams and photographs.

After reading the Level W books, readers should be able to progress to Level X.

Use the following to assess whether your student's progress indicates he or she is ready to move up a level:

• Level W Benchmark Book
