Conduct investigations to reach qualitative and quantitative conclusions regarding the effects of the size of the total force and the object’s mass on its resulting acceleration (Newton’s 2nd Law, a = Ftotat/m). Observe how the direction of the acceleration relates to the direction of the total force.
Science is a human endeavor involving knowledge learned through inquiring about the natural world. Scientific claims are evaluated and knowledge changes as a result of using the abilities and understandings of inquiry. The pursuit of scientific knowledge is a continuous process involving diverse people throughout history. The practice of science and the development of technology are critical pursuits of our society.
Scientific inquiry involves asking scientifically-oriented questions, collecting evidence, forming explanations, connecting explanations to scientific knowledge and theory, and communicating and justifying the explanation.
