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, conclusion and an afterthought. A second page reiterates the question, asking the students to fill in a report, with their prediction, procedure used, observations and conclusions. Learn about how spinning affects air pressure, why simple machines can lift objects easier and more! Evaluation & conference forms included, as well as puzzle answer key. 95 classroom reproducible pages, softcover. Grades 4-6.
