What it is

A three-volume teacher's text by scientist and educator Bernard Nebel: Volume I for K-2, Volume II for grades 3-5, and Volume III for grades 6-8. Lessons run along four learning progressions (the nature of matter, life science, physical science, and earth and space science) that are taught in tandem and rely on observation, reasoning, and question-and-answer discussion. The lesson plans guide the teacher or parent through each lesson, and a free online support site adds images and videos.
