- Abstract:
-
Students construct a rocket from a balloon propelled along a guide string. They use this model to learn about Newton's three laws of motion, examining the effect of different forces on the motion of the rocket.

Students observe the relationship between the angle of a catapult (a force measurement) and the flight of a cotton ball. They learn how Newton's second law of motion works by seeing directly that F = ma. When they pull the metal "arm" back further, thus applying a greater force to the cotton ball, it causes the cotton ball to travel faster and farther. Students also learn that objects of greater mass require more force to result in the same distance traveled by a lighter object.

This learning video describes within an action orientation certain often difficult-to-understand concepts of Newtonian physics. The conservation of momentum is extended to rotational situations, and some of the results may be counter-intuitive! As Professor Lewin states in the opening segment, the prerequisite necessary for this lesson includes familiarity with the concepts of torque, angular velocity, angular momentum and moment of inertia. This interactive video lesson can easily be completed within a 55-minute class period, and the only material required is a blackboard/whiteboard to write on. During the breaks between video segments, students will be asked to think about and discuss: conditions under which angular momentum is either conserved or not conserved; examples in which the moment of inertia changes; a human ice skater and a rough estimation of her moment of inertia; as well as other topics.

This activity introduces students to the basic physics concepts on how rockets work through the building and testing of a model rocket fueled by an antacid. Students have the opportunity to revise and improve their initial design. Note: This activity is similar to film canister rockets that students make in elementary school but is adapted for middle school.

Students learn why and how motion occurs and what governs changes in motion, as described by Newton's three laws of motion. They gain hands-on experience with the concepts of forces, changes in motion, and action and reaction. In an associated literacy activity, students design a behavioral survey and learn basic protocol for primary research, survey design and report writing.

- Abstract:

Students design and build a paper rocket around a film canister, which is used as the engine. An antacid tablet and water are put into the canister, react to form carbon dioxide gas, and act as the pop rocket's propellant. With the lid snapped on, the continuous creation of gas causes pressure to build up until the lid pops off, sending the rocket into the air. The pop rockets demonstrate Newton's third law of motion: for every action, there is an equal and opposite reaction.

Building upon their understanding of forces and Newton's laws of motion, students learn about the force of friction, specifically with respect to cars. They explore the friction between tires and the road to learn how it affects the movement of cars while driving. In an associated literacy activity, students explore the theme of conflict in literature, and the difference between internal and external conflict, and various types of conflicts. Stories are used to discuss methods of managing and resolving conflict and interpersonal friction.

The airplanes unit begins with a lesson on how airplanes create lift, which involves a discussion of air pressure and how wings use Bernoulli's Principle to change air pressure. Following the lessons on lift, students explore the other three forces acting on airplanes thrust, weight and drag. Following these lessons, students learn how airplanes are controlled and use paper airplanes to demonstrate these principles. The final lessons addresses societal and technological impacts airplanes have had on our world. Students learn about different kinds of airplanes and then design and build their own balsa wood airplanes based on what they have learned.
