One-sided worksheet that slowly guides students through the process of understanding and predicting events by using what they know about Newton's First Law of Motion. The handout asks students to provide an explanation by using their knowledge of Newton's First Law and applying it to a hypothetical situation. The worksheet is best used as an independent practice activity after student's have a basic understanding of Newton's First Law. This handout is not meant to teach the student's about Newton's First Law, but rather check their understanding of the law. The activity will take roughly 10-15 minutes to complete.
