This page provides a set of context-rich physics problems on conservation of energy and conservation of momentum. Each context-rich problem is based on a real-world situation, and includes both information that is relevant to solving the problem and extraneous information. Strategies for problem solving are not explicitly provided. Each problem is formulated so it is too difficult for one student to solve alone, yet not too difficult for a group to master. This resource is based on the research results of the Minnesota Physics Education Research group. See Related items on this page for a link to the full collection. (less)

This experiment explores the behavior of a pair of loosely coupled compass needles in air with weak damping. The needles are far enough apart that the magnetic interaction between their magnetic dipoles is much weaker than their interaction with the Earth's magnetic field. The resulting motion displays beats--when one compass is momentarily at rest, the other oscillates with maximum amplitude. (less)

This website is designed to introduce kids to engineering. It includes a section with brief career profiles of various engineering career paths, but the real fun is in the videos. Featuring kids engaged in activities that illuminate key concepts in engineering, these videos showcase the work of engineering in a dynamic and exciting format. For example, one video covers the biomechanics of skateboarding -- taking real kids on a field trip to the Etnies Shoes headquarters where they learn how engineers (who are also skateboarders) use science to design shoes that help absorb impact and minimize injury. Another video takes a group of kids to Disney World to experience how Disney engineers transform potential energy into thrilling roller coaster rides. All of the videos feature a related hands-on activity to let students apply the science concepts involved. Editor's Note: Don't miss the section "Cool Stuff" for games and activities that help students connect the science principles with engineering practice. For easy downloading or full-screen viewing, see Related Materials for a link to the You Tube version of the roller coaster video. (less)

Students evaluate various everyday energy conversion devices and draw block flow diagrams to show the forms and states of energy into and out of the device. They also identify the forms of energy that are useful and the desired output of the device as well as the forms that are not useful for the intended use of the item. This can be used to lead into the law of conservation of energy and efficiency. The student activity is preceded by a demonstration of a more complicated system to convert chemical energy to heat energy to mechanical energy. Drawing the block energy conversion diagram for this system models the activity that the students then do themselves for other simpler systems. (less)

This tutorial offers straightforward information on energy basics, forms of energy, renewable and nonrenewable energy sources, energy transfer, and a historical perspective of scientific breakthroughs in the field. It includes games, experiments, and an Energy IQ test for the middle grades. Especially noteworthy are the diagrams, tables, and images that support the text. This resource was developed by the U.S. Energy Information Administration, an independent organization that collects, analyzes, and disseminates impartial energy information to promote public understanding of issues relating to energy use. <i>Editor's Note: The authors developed this resource for use in the middle grades, but the readability score ranges from Grade 10 to Grade 13 (depending upon the index used). It is appropriate for independent student use in high school settings, however, we recommend scaffolding for use in middle school.</i> (less)

The Energy and Momentum Conceptual Survey is a 25-question research-based multiple-choice test designed for students in algebra- and calculus-based introductory classes. The survey is based on investigations of students’ difficulties in momentum and energy and should be administered in a 50-minute period. Statistical results have shown the survey to be reliable and valid. A summary of the construction and analysis of the survey is available in C. Singh and D. Rosengrant, <em>Multiple-choice test of energy and momentum concepts</em>, Am. J. Phys. <b>71</b> (6), 607-619 (2003). This assessment is free for use by instructors in their classroom. However, as it takes years of development effort to create and validate reliable assessment instruments, the file is password-protected. Furthermore, the author requests that 1. students are not given copies following examination; and 2. none of the questions are incorporated into web-based question delivery systems without adequate security to prevent printing or unauthorized access by students.

Energy of Motion

By taking a look at the energy of motion all around us, students learn about the types of energy and their characteristics. They first learn about the two simplest forms of mechanical energy: kinetic and potential energy, as illustrated by pendulums and roller coasters. They come to understand that energy can change from one form into another, and be described and determined by equations. Through the example of a waterwheel, the concepts of and differences between work and power are explained and calculated. Conservation of momentum and collisions are explored, with analogies to popular sports (billiards, baseball, golf), and how elastic and inelastic collisions are considered in the games' design. To show another energy transformation concept, the behavior of energy dissipating into heat by means of friction is presented. Students learn to recognize static friction, kinetic friction and drag, how they work, and how to calculate frictional force. A final lesson integrates the energy of motion concepts, showing how they are interconnected in everyday applications such as skateboards, scooters, roller coasters, trains, cars, planes, trucks and elevators. Through numerous hands-on activities, students swing pendulums, use plastic two-liter bottles to construct model waterwheels, bounce different types of balls, use weights to generate friction data, and roll balls down ramps to collide into cups.

This unit provides students the opportunity to explore methods engineers have devised for harnessing sunlight to generate power. Students will initially explore heat transfer and heat storage through the construction, testing, and eventual use of a solar oven. With a lesson focused on photovoltaic cells, students will learn the concepts of energy conversion, conservation of energy, current, and voltage. Through construction of model solar powered cars, students can see these conceptual ideas manifested in modern technology. Furthermore, the solar car project provides opportunities to explore a number of other topics, such as gear ratios and simple mechanics. Both of these design and construction projects are examples of engineering design. (less)
