Lesson Plan : Newton's Law of Motion

 Teacher Name: Bryantie Harris Grade: Grade 7-8 Subject: Science

 Content: Vocabulary: inertia Unbalanced Velocity Action Force Newton’s Laws of Motion Force Mass Equal Force Motion Acceleration Reaction Force Objectives: S.O.L. P.S. 10: The student will investigate and understand scientific principles and technological applications of work, force and motion. A. To understand how inertia affects moving and non moving objects. B. To understand what effect an unbalanced force has on moving objects. C. To understand the difference between action and reaction force. Materials: Hula hoops of different sizes Paper (2 pieces) Markers Rulers Paper cups Protractors Pencils Introduction: Making a paper air plane Development: Identify situations that illustrate each Law of motion. A. Newton’s first Law-of-Motion: explains how inertia affects moving and non-moving objects. An object will remain at rest or move at a constant speed in a straight line unless it is acted on by an unbalanced force. B. Newton’s Second Law–of-Motion: states that the unbalanced forces acting on an object is equal to the mass of the object times its acceleration. F= m a C. Newton’s Third Law-of-Motion: explains how rocket engines work. Hot gases are forced out of the back of the rocket. (Action Force) The gases exert an equal and opposite force on the rocket.(Reaction Force) The reaction force pushes the rocket upward. Practice: A. Using hula hoops of different sizes and weights to test newton’s First Law of Motion. B. Make a paper airplane to test Newton’s Third Law of Motion. Checking For Understanding: Student demonstrations Classroom observations Student laboratory Reports Quizzes Informal test Closure: Summarizing and note taking Homework and practice Cooperative learning Setting objectives and providing feedback Generating and testing hypothesis Cues, questions and advance organizers
