The universe and its components are studied in another unit. The twenty-four lessons and six unit reviews present the material in an easy-to-teach manner. Students keep a science notebook. Hands-on projects include a model of Earth and layers, simulating a volcanic eruption, and more. Grades 3rd-8th. Christian Kids Explore Series from Bright Ideas Press. 2006
