Acquaint your students not only with a variety of motion and machine experiments, but also with the scientific thinking that produced many of them. Activities start with a question, and include a materials needed list, step-by-step procedure and a conclusion. A second page reiterates the question, asking the students to fill in a report with their prediction, procedures, observations and conclusion; it also includes room for them to draw a picture of what it looked like. Answer key included. 96 classroom reproducible pages, softcover. Grades 4-6.
