kinetic (or moving) energy. (Grade Energy can be stored in chemicals (food, batteries), height (gravitational), elastic stretching, etc. Remind students that energy can be converted from one form to another. Everywhere you look, in all sorts of different forms, energy is present and important in our daily lives. At the highest point kinetic energy is zero / maximum while the potential energy is zero / maximum. How do you use them? Require students to use the energy terminology learned in the lesson (and provided in a word bank on the slide). Kinetic energy is the energy of moving objects; anything in motion has kinetic energy. The heavier an object, the more kinetic energy it has when in motion. Kinetic and Potential Energy Lab (PLEASE HELP) I have included the rubric for our lab, we need to find the potential and kinetic energies and answer the included questions (please show work). 5), Reason abstractly and quantitatively. Kinetic energy is energy in the form of motion, such as in a bouncing ball. (Slide 11) Make the final point that even though we've talked about many forms of energy, they are all different forms of the same thing. The presentation is animated, so clicking brings up the next image, text or slide. ★ ★ Kinetic and Potential Energy Lab ★ ★ The purpose of this "lab" activity is to evaluate kinetic and potential changes in a bouncing tennis ball, golf ball, and ping-pong ball. ... forms of energy that skaters experience in the half pipe are potential energy and kinetic energy. Example Answer Key Examples of kinetic energy: x Swinging a bat. Examples of potential energy: x Holding a baseball. The higher an object, the more gravitational energy it has. One of the most important concepts about energy is that energy can be neither created nor destroyed; it can only be transferred, or converted, from one form to another. (Slide 12) Using the writing prompt on this slide (and description in the Assessment section), assign students to write about three fictional superpowers, and then read them to the class. Electricity powers light bulbs so we can continue to study, work and have fun after dark. PART A: Exploring the Skate Park. If an object's mass is doubled, its kinetic energy under the same speed is also doubled. 1. Do you agree with this alignment? AN OBJECT THAT HAS MOTION, NO MATTER THE DIRECTION, HAS KINETIC ENERGY. Write a paragraph explaining: What are your superpowers? [Note: The purpose of these questions is to activate prior knowledge and get students thinking. x Running around the block. Students are introduced to both potential energy and kinetic energy as forms of mechanical energy. During a physics unit, have students explore potential and kinetic energy with these five fun experiments that encourage problem solving and play. x��ko�F����t�(.�|�������/qz8�E@K��F�T���3�o�K;�C`�;3;���_���^t�������7͒}��l�n{����ۮ���׫Mݭ���cv��\<9��⬊��]\=9�,��"��R���8|�}r�k����ѧ��tƳI=�b�n�I��� ��ΪI;���-~���>y�� |��>�ϧ�rr?�&�5ޯ�٤����l`X�b�E �d�LJ��M&s�U���-���ɟ���� "����W��/��� (Grade What kind of energy do they use? The answer to each will be either conduction, convection, or radiation. MS-PS3-5: Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object. Bounce lab potential and kinetic energy answer key 353 Golf Ball 0. height in meters : height in cm ÷ 100 _____ 20. Related Curriculum shows how the document you are currently viewing fits into this hierarchy of curricular materials. Build your own system, with energy sources, changers, and users. Information: Energy is the ability to cause change. gravitational energy: Energy that is stored in the height of objects. It is helpful to graph the relationship on the classroom board or show students a simulation to demonstrate the relationship, such as The Ramp from PHET Interactive Simulations at http://phet.colorado.edu/en/simulation/the-ramp. The contents of this digital library curriculum were developed by the Renewable Energy Systems Opportunity for Unified Research Collaboration and Education (RESOURCE) project in the College of Engineering under National Science Foundation GK-12 grant no. Materials: 4 plastic cups Ruler Straw Sturdy stick (could use a chopstick) Tape. Fireplaces, electrical heaters and gas furnaces provide warm indoor air so we can survive when the weather is freezing. Explore how heating and cooling iron, brick, water, and olive oil adds or removes energy.

Marble- Potential Energy. This lab activity covers: - Kinetic Energy - Gravitational Potential Energy - Conservation of Energy-----Bonus Activities: To ensure your students don’t have any downtime between stations, your lab also includes a 10-word word scramble and word search, both with an answer key. The most kinetic energy? This energy is released during chemical reactions. kinetic energy IS THE ENERGY OF MASS IN MOTION. copyrightCopyright © https://phet.colorado.edu/sims/cheerpj/the-ramp/latest/the-ramp.html?simulation=the-ramp. What is the Kinetic Energy of a 150 kg object that is moving with a speed of 15 m/s? Alignment agreement: Often, gravitational energy (a form of potential energy) is converted to kinetic energy to make things move fast. Thanks for your feedback! 7). Draw the beaker from the colored ice cube lab and fully explain what happened and why. THE LAB ACTIVITY. In this lab, you will analyze energy transfer between gravitational potential energy, kinetic energy, and energy lost due to collisions or friction (thermal energy) as a skate boarder rides along a track. conservation of energy. Can you think of some more examples of energy conversion from one form to another? http://office.microsoft.com/en-us/images/results.aspx?qu=climb&ex=1#ai:MP900427841|mt:2|. 2 0 obj Two real-world... Students are introduced to the definition of energy and the concepts of kinetic energy, potential energy, and energy transfer. Students understand how kinetic and potential energy relate within a system. All rights reserved. Track and visualize how energy flows and changes through your system.

This energy is released during chemical reactions. stream The presentation contains review questions and activities that ask students to use their new energy knowledge. energy: The ability to make things happen. We also discussed that stored energy is called potential energy, and that type of energy … The faster an object moves, the more kinetic energy it has. The law of conservation of energy tells us that we can never create or destroy energy, but we can change its form. An object moving with a speed of 67 m/s and has a kinetic energy of 500 J, what is the mass of the object. Each object can only have a certain amount of energy and that energy is in different forms. Gravity is the force that pulls things down to Earth. You have three energy superpowers! (Slide 2) As a class, verify students' understanding of concepts learned in the previous lesson by asking them to define the following terms: energy, kinetic energy, potential energy and energy transfer. After students are done, give them time to share their answers with the class. Make sure students communicate using the energy terms learned in the lesson. KE = ½ mv2 KE = ? (Grade The same kinetic energy (two points) and C Conclusion Questions: (circle the correct answers) 1. And food, grown with the energy from the sun, is our fundamental source of energy to support our lives. Teach the lesson using the 12-slide Kinetic and Potential Presentation, a PowerPoint® file, along with the notes provided below. Potential Energy (PE) is stored energy due to position or state PE due to gravity = m g h 3.
