1 Department of Mathematics and Science Physical Science Big Idea 10: Forms of Energy Big Idea 11: Energy Transfer and Transformation Grade 5 Quarter 2 Topics 8 & 9 What is Energy? Mary Tweedy, Curriculum Support Specialist Keisha Kidd, Curriculum Support Specialist Millard Lightburn, District Supervisor

2 Department of Mathematics and Science Big Idea 10: Forms of Energy Big Idea 10: Forms of Energy Big Idea 11: Energy Transfer & Transformation Benchmarks SC.5.P Investigate and describe some basic forms of energy, including light, heat, sound, electrical, chemical, and mechanical. Also Assesses: SC.5.P Investigate and explain that energy has the ability to cause motion or create change. SC.4.P Investigate and explain that sound is produced by vibrating objects and that pitch depends on how fast or slow the object vibrates. SC.4.P Describe how moving water and air are sources of energy and can be used to move things. SC.3.P Demonstrate that light travels in a straight line until it strikes an object or travels from one medium to another. SC.3.P Demonstrate that light can be reflected, refracted, and absorbed. SC.3.P Investigate, observe, and explain that things that give off light often also give off heat. SC.3.P Investigate, observe, and explain that heat is produced when one object rubs against another, such as rubbing one's hands together.

3 Department of Mathematics and Science SC.5.P Investigate and explain that electrical energy can be transformed into heat, light, and sound energy, as well as the energy of motion. Also Assesses: SC.3.E Demonstrate that radiant energy from the sun can heat objects and when the sun is not present, heat may be lost. SC.4.P Recognize that heat flows from a hot object to a cold object and that heat flow may cause materials to change temperature. SC.4.P Identify common materials that conduct heat well or poorly.

4 Department of Mathematics and Science 4 What is Energy? Energy is the ability to do work. Energy Energy is the ability to cause a change. Energy can change an objects: motion shape temperature color

5 Department of Mathematics and Science Energy is all around us! – You can hear energy as sound when someone talks. – You can see mechanical energy every time you move. – You can see energy as light from the sun or a lamp. – You can feel it as heat warms things up. Discovery Fundamentals: Energy Makes it Happen

6 Department of Mathematics and Science What are the Forms of EnergyWhat are the Forms of Energy? Electrical Light Sound Chemical Heat/Thermal Mechanical kinetic potential /

7 Department of Mathematics and Science Kinetic Energy Energy due to motion. Types of kinetic energy Kinetic energy can change into other forms of energy.

8 Department of Mathematics and Science Potential Energy Stored energy that could cause change in the future. Potential energy is stored energy--energy ready to go. A lawn mower filled with gasoline, a car on top of a hill, and students waiting to go home from school are all examples of potential energy. Types of potential energy gravitational compressed spring chemical magnetic

9 Department of Mathematics and Science Mechanical Energy Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position)kinetic energypotential energy All energy can be in one of two states: potential energy or kinetic energy. The amount of mechanical energy depends on the objects speed and mass. Mechanical energy can change into other forms of energy.

10 Department of Mathematics and Science Chemical Energy Chemical energy is made when substances react and form new substances. Food, batteries, and fuels such as oil and gasoline are stored chemical energy. Chemical energy can change to: Chemical energy soundlight thermal electrical kinetic

11 Department of Mathematics and Science What is Sound? https://www.pearsonsuccessnet.com/snpapp/login/login.jsp Sound is a form of energy produced by a Sound vibration or a back and forth movement of an object. Sound is a wave of vibrations that spread from its source of its matter. The more vibrations the waves have, the more energy, the louder the sound. The faster the vibrations or the frequency, the higher the sound. How high or low a sound is called the pitch.

12 Department of Mathematics and Science What is light? Light is something that allows us to see objects. Light is a form of energy. Light Light is produced by the vibrations of electrically charged particles.

13 Department of Mathematics and Science Properties of Light Light travels in a straight path. Light doesnt travel through all objects. These are defined as opaque. Light can be absorbed and changed to heat.

14 Department of Mathematics and Science Properties of Light Continued Light bounces off or is reflected from some kinds of opaque objects. Some objects let all light pass through them are known as: transparent Some objects let some light pass through them are known as: translucent Angles of Reflection

15 Department of Mathematics and Science Bending Light Lab Write down responses on your note page. Problem: What does light do when it travels from one medium or state of matter (air) through another medium (water)? Hypothesis: Test and Observe: Follow steps from the lab sheet. Conclusion:

16 Department of Mathematics and Science Light Changes Direction Light bends or refracts as it passes from one medium (form of matter: solid, liquid or gas) to another. Refraction of Light Virtual Tutorial

17 Department of Mathematics and Science What is Thermal Energy? Thermal energy is the total of all the kinetic Thermal energy and potential energy of the atoms in an object. When any form of matter gets warmer, the kinetic energy of its atoms increases. The objects particles move faster, so its thermal energy increases. A change in thermal energy can lead to a change in phase or state of matter. Temperature is a measure of thermal energy.

18 Department of Mathematics and Science Forms of Energy Energy Forms Heat/thermal Electrical Chemical Mechanical: potential kinetic Light /Radiant What Happens? Objects warm. Food cooks. Lights on. / Machines run. Organisms move and grow. Flashlights light up. Sled sits on top of a hill. Sled slides down the hill. Plants grow. / Lasers cut.

19 Department of Mathematics and Science What is the Transformation of Energy? Energy can change and move from one object to another. chemical > electrical > light Where does the energy of a lit light bulb transfer to after the flashlight has been on for a while? Heat energy transfers into the air.

20 Department of Mathematics and Science Forms of Energy Stationstaions Identify and record the different forms of energy in your science notebook as you rotate throughout the various stations. Reflections: Describe what you learned in the energy stations. What was interesting? What do you want to learn more about?

21 Department of Mathematics and Science What are some transfers and/or transformations of energy that are taking place in our classroom, in our school or at home?

22 Department of Mathematics and Science Transformation of Energy A. B. A. B. C.

23 Department of Mathematics and Science Energy Transformation How is energy changing when a toaster is in use? A toaster uses electrical, mechanical, and thermal energy.
