A very informative slide show breaks mechanical energy down into components for your physics whizzes. They learn about two types of potential energy and the work energy theorem. They are given the tools needed to perform potential and kinetic energy calculations. Finally, they discover how to determine stopping distance for an object coming to rest. This is a practical presentation to include in your physics lessons.
Seventh graders explore about energy transformations and trace them in a simple closed system. They build energy "chains" of their own design. Pupils complete a hands-on project where they attach the "links" in a "chain" connecting a battery (chemical energy), wires (electrical energy), and a small motor (mechanical energy), and then add additional "links" of their choices. Students complete a flowchart tracing the energy transformations in the finished project.
Middle schoolers participate in an activity in which they observe a ball as it rolls down an incline into a cup. They take measurements and use equations that describe the concepts of mechanical energy, work and power, momentum, and friction. They calculate unknown variables regarding these concepts.
Wow! Colorful and simple, these 160 slides introduce the various forms of energy, along with a relevant image. Some of the images are animations, which help beginning physical scientists to visualize the flow of electrons or energy! This PowerPoint would be great to bring energy concepts to your class, including transformation of energy, energy transfer, and the law of conservation of energy. Use some or all of the slides to your liking!
Students drop water from different heights to demonstrate the conversion of water's potential energy to kinetic energy. They see how varying the height from which water is dropped affects the splash size. In seeing how falling water can be used to do work, they also learn how this energy transformation figures into the engineering design and construction of hydroelectric power plants, dams and reservoirs.
Instructions for series of six activites, a reading of scientific literature, and a choice of six assessments await you in this physics resource. Well-written plans guide you in guiding your pupils to experiment with levers, pulleys, rolling marbles, springs, and more. They will learn that energy is conserved, transferred into other forms, and how to put it to use in practical terms. Mathematical equations are employed in each activity, making these lessons most appropriate for high school physics.
Ninth graders experiment with bouncing balls to investigate the elasticity coefficient of different sizes and types of balls. In this superball physics lesson, 9th graders bounce various types of balls from differing heights. They examine formulas that predict the bounce back height and the mechanical energy remaining after the ball is dropped. Students then use these formulas to answer performance assessment questions.
