https://www.oercommons.org/courses/give-me-a-brake
In this activity, learners explore the concept of how brakes can stop or slow mechanical motion. Learners examine the operation of a bicycle brake and use low cost materials to devise a simple braking system, then work as a team to suggest improvements to current bicycle brake designs.IEEEEngineeringTechnologyEducationHistory, Law, PoliticsMathematicsChemistryPhysicsSocial Sciences2015-12-23T22:59:51.765298Course Related MaterialsKinetic and Potential Energy of Motion

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.Bailey JonesChris YakackiDenise CarlsonIntegrated Teaching and Learning Program,Malinda Schaefer ZarskeMatt LundbergEducation2015-10-16T16:43:19.231919Course Related MaterialsWork and Power: Waterwheel

Investigating a waterwheel illustrates to students the physical properties of energy. They learn that the concept of work, force acting over a distance, differs from power, which is defined as force acting over a distance over some period of time. Students create a model waterwheel and use it to calculate the amount of power produced and work done.Bailey JonesChris YakackiDenise W.

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.Office of Educational Partnerships,Susan Powers, Jan DeWaters, and a number of Clarkson and St. Lawrence University students in the K-12 Project Based Learning Partnership ProgramEducation2015-10-16T16:41:44.257981Course Related MaterialsEnergy Forms and States Demonstrations

Demonstrations explain the concepts of energy forms (sound, chemical, radiant [light], electrical, atomic [nuclear], mechanical, thermal [heat]) and states (potential, kinetic).Office of Educational Partnerships,Susan Powers, Jan DeWaters, and a number of Clarkson and St. Lawrence University students in the K-12 Project Based Learning Partnership ProgramEducation2015-10-16T16:41:39.742056Course Related MaterialsEnergy Forms, States and Conversions

Students participate in many demonstrations during the first day of this lesson to learn basic concepts related to the forms and states of energy. This knowledge is then applied the second day as students assess various everyday objects to determine what forms of energy are transformed to accomplish the object's intended task. Students use block diagrams to illustrate the form and state of energy flowing into and out of the process.Office of Educational Partnerships,Susan Powers, Jan DeWaters, and a number of Clarkson and St. Lawrence University students in the K-12 Project Based Learning Partnership ProgramEducation2015-10-16T16:41:36.443149Course Related Materials
