Daily life provides students with many experiences—for example, riding in cars, participating in sports activities, doing household chores—through which they can see evidence of forces and energy changes as well as the use of machines to make work easier.
In Energy, Machines, and Motion, students investigate energy and the different forms it can take, how forces do work to change energy from one form to another, how machines reduce the effort force needed to do work, and how forces change the motion of objects.
Each lesson in this module builds on skills and concepts presented in previous lessons. As students progress through the module, they take greater responsibility for their own learning, eventually planning and conducting their own procedures, devising their own data tables, and analyzing the results they obtain.
Energy, Machines, and Motion is organized into three parts: Energy, Machines, and Motion. A conceptual sequence chart for the module appears under Downloads.

Energy: Students investigate energy transformations and how forces do work to transform energy. They build a battery and develop evidence that energy is stored in the battery. Using rechargeable alkaline batteries, students see how chemical energy can be transformed into light, heat, and mechanical energy and how charging time is related to the energy stored in the battery. Students next investigate the nature of elastic forces, gravity, and sliding friction and learn how these forces can do work. Through experimentation they determine the optimum operating conditions for a small electric motor. They find that the electric motor cannot exert enough force to lift the K’NEX® sled they built. This challenge—to lift the sled a given height—forms the basis of their study of three machines.Machines: Students learn how simple machines work. They explore the relationship between effort force and effort distance by lifting their sled using inclined planes, pulleys, and levers. They determine the mechanical advantage and efficiency of each machine. The assessment for Part 2 is a technological challenge in which students design a motor/machine combination that will lift their sled to a given height.
Motion: Students explore the motion of three vehicles that they construct. They build a fan car, a mousetrap car, and a roller coaster and determine how the forces applied to the vehicles change their speed. They also describe the motion of the vehicles in terms of energy transformations and apply the principle of conservation of energy to explain their observations.
Anchor Activity: This is a research project where students analyze a device they use in their everyday lives. They demonstrate and explain the physical principles of the device and share what they learned through visual displays and oral presentations.
Each part of the unit begins with an assessment of students’ current
understanding of the topic and ends with performance-based and written
assessments. |
