Through four lessons and four hands-on associated activities, this unit provides a way to teach the overarching concept of energy as it relates to both kinetic and potential energy. Within these topics, students are exposed to gravitational potential, spring potential, the Carnot engine, temperature scales and simple magnets. During the module, students apply these scientific concepts to solve the following engineering challenge: "The rising price of gasoline has many effects on the US economy and the environment. You have been contracted by an engineering firm to help design a physical energy storage system for a new hybrid vehicle for Nissan. How would you go about solving this problem? What information would you consider to be important to know? You will create a small prototype of your design idea and make a sales pitch to Nissan at the end of the unit." This module is built around the Legacy Cycle, a format that incorporates findings from educational research on how people best learn. This module is written for a first-year algebra-based physics class, though it could easily be modified for conceptual physics.

Students are introduced to the concept of inertia and its application to a world without the force of friction acting on moving objects. When an object is in motion, friction tends to be the force that acts on this object to slow it down and eventually come to a stop. By severely limiting friction through the use of the hover pucks, students learn that the energy of one moving puck is transferred directly to another puck at rest when they collide. Students learn the concept of the conservation of energy via a "collision," and will realize that with friction, energy is converted primarily to heat to slow and stop an object in motion. In the associated activity, "The Puck Stops Here," students will investigate the frictional force of an object when different materials are placed between the object and the ground. This understanding will be used to design a new hockey puck for the National Hockey League.

Students investigate potential energy held within springs (elastic potential energy) as part of the Research and Revise step. Class begins with a video of spring shoes or bungee jumping. Then students move on into notes and problems as a group. A few questions are given as homework. The Test Your Mettle section concludes. The lesson includes a dry lab that involves pogo sticks to solidify the concepts of spring potential energy, kinetic energy and gravitational energy, as well as conservation of energy.

In this lesson, students are introduced to both potential energy and kinetic energy as forms of mechanical energy. A hands-on activity demonstrates how potential energy can change into kinetic energy by swinging a pendulum, illustrating the concept of conservation of energy. Students calculate the potential energy of the pendulum and predict how fast it will travel knowing that the potential energy will convert into kinetic energy. They verify their predictions by measuring the speed of the pendulum.

Mechanical energy is the most easily understood form of energy for students. When there is mechanical energy involved, something moves. Mechanical energy is a very important concept to understand. Engineers need to know what happens when something heavy falls from a long distance changing its potential energy into kinetic energy. Automotive engineers need to know what happens when cars crash into each other, and why they can do so much damage, even at low speeds! Our knowledge of mechanical energy is used to help design things like bridges, engines, cars, tools, parachutes, and even buildings! In this lesson, students will learn how the conservation of energy applies to impact situations such as a car crash or a falling object.

Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, and the amplitude of the swing. It's easy to measure the period using the photogate timer. You can vary friction and the strength of gravity. Use the pendulum to find the value of g on planet X. Notice the anharmonic behavior at large amplitude.

This is a lab activity involving transformations between the gravitational potential energy, elastic potential energy, and kinetic energy of a system. An air track with a glider and a photo gate timer are needed to perform the lab. The lab is divided into three separate but related parts. The first part involves using a spring to launch the glider horizontally, measuring the velocity of the glider, and then relating elastic potential energy to kinetic energy. The second activity involves adjusting the air track so that when the glider is launched, it goes up an incline. This set up allows students to relate elastic potential energy to gravitational potential energy. The third and final activity ties elastic potential, gravitational, and kinetic energy together. Using the knowledge they acquired from the first two activities, the students need to use Conservation of Energy to predict the velocity of the glider as it is launched up the incline and then compare their prediction to the experimental value.

After learning about the concept of transfer of energy, specifically the loss of kinetic energy to friction, students get a chance to test friction. Student groups are each given a wooden block and different fabrics and weights and challenged to design the "best" puck. First the class defines what makes the "best" puck. They come to realize that the most desirable puck is the one that travels the farthest, thus the puck with the least amount of friction. In the context of hockey, the "best" puck is the one that travels farthest and loses the least kinetic energy to friction. Students then apply their knowledge of friction the energy transfer from kinetic to heat energy to design new, optimal pucks for the National Hockey League.
