Description
Just as the human body is made of systems that work together, so is the earth. This earth science unit takes a look at the parts of these systems, the earth’s spheres, including the lithosphere, biosphere, hydrosphere, and atmosphere. The layers of the earth, the atmosphere, and the ocean are also studied. Following this section, the earth’s cycles are explored, including the water cycle, oxygen cycle, nitrogen cycle, and carbon cycle. Various aspects of the water cycle are explored including watersheds and water purification. Numerous diagrams are given to help make these concepts accessible and easier to understand.
At the end of the unit, students can review 29 vocabulary words, label several related diagrams, and enjoy a review activity. Answer keys are provided. 30 pages total. Ages 11-13.
All measurements are given in both English and metric. This title does not discuss origins or the age of the earth. If you would like to explore the topics in this book from a Creation science worldview, free downloadable discussion helps are available.
