    2. Big Idea 10: Forms of Energy Big Idea 11: Energy Transfer & TransformationBenchmarks SC.5.P.10.1 - Investigate and describe some basic forms of energy, including light, heat, sound, electrical, chemical, and mechanical. SC.5.P.10.2 - Investigate and explain that energy has the ability to cause motion or create change. SC.5.P.10.4 - 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.4.P.10.3 - 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.10.4 - Describe how moving water and air are sources of energy and can be used to move things. SC.3.P.10.3 - Demonstrate that light travels in a straight line until it strikes an object or travels from one medium to another. SC.3.P.10.4 - Demonstrate that light can be reflected, refracted, and absorbed. SC.3.P.11.1 - Investigate, observe, and explain that things that give off light often also give off heat. SC.3.P.11.2 - Investigate, observe, and explain that heat is produced when one object rubs against another, such as rubbing one's hands together. SC.2.P.10.1 - Discuss that people use electricity or other forms of energy to cook their food, cool or warm their homes, and power their cars.

    3. What is Energy? Energy is the ability to do work. Energy is the ability to cause a change. Energy can change an object’s: motion shape temperature color 3

    4. 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

    5. Electrical Chemical Heat/Thermal Mechanical kinetic potential Sound Light What are the Forms of Energy?

    6. What is Potential Energy? Stored energy that could cause change in the future. It’s energy that’s ready to go.  What are some examples? A lawn mower filled with gasoline, a sled on top of a hill, a slinky on a stairs and a yo-yo are all examples of potential energy ready to change to kinetic energy. Types of potential energy • gravitational • chemical • magnetic • compressed spring

    7. Choose a toy to observe • Describe what the toy does. • Can the toy change speed or directions? If so, what caused it to do that? • Where does its energy come from? • What caused the stored energy to be converted to kinetic energy? • At what point does the toy have its most kinetic energy?

    8. What is Kinetic Energy? Energy due to motion. What affects the amount of kinetic energy in a moving object? • its speed • Its mass • Kinetic energy can change into other forms of energy.

    9. What is 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) What does the amount of mechanical energy depend on? the object’s speed and/or mass • What forms of energy can mechanical energy change into? .

    10. What is Sound? • Sound is a form of energy produced by a vibration or a back and forth movement of an object. • Sound is a wave of vibrations that spread from its source of its matter. What are properties of sound? • Loudness - The more vibrations the waves have, the more energy, the louder the sound. • Pitch - How high or low a sound is. The faster the vibrations or the frequency, the higher the sound.

    11. What is light? • Light is something that allows us to see objects. • Light is a form of energy. • Light is produced by the vibrations of electrically charged particles.

    12. What are Properties of Light? • Light travels in a straight path. • Light doesn’t travel through all objects. These are defined as opaque. • Light can be absorbed and changed to heat.

    13. More Properties of Light… • Light bounces off or is reflected from some kinds of opaque objects. • What are objects that let all light pass through them known as? transparent • What are objects that let some light pass through them are known as? translucent Angles of Reflection

    14. Bending Light LabWrite 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: • Apply: Draw a light path though a cup of water and explain it.

    15. When does 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

    16. What is ThermalEnergy? • Thermal energy is the total of all the kinetic and potential energy of the atoms in an object. • When any form of matter gets warmer, the kinetic energy of its atoms increases. • The object’s 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.

    17. Quiz: Constructed Response

    18. What is 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: light heat/thermal sound electrical mechanical

    19. How Do People Get Energy? Yourbody gets nutrients from eating food. It gets energy from some of these nutrients. You need energy to do activities. When you walk, talk, sleep, sneeze, or pet a dog, you use energy. You also need energy for your body to function on the inside. You need energy for your heart to beat and your brain to think. It’s a good thing your digestive system helps your body get the nutrients and energy it needs!

    20. Read A Day in Your Digestive System • What is the purpose of the body’s digestive system? • What are its main organs and their functions? • In what organ are the nutrients that provide energy released into the blood stream? • Explain one way that energy is transformed in your body.

    21. Energy Forms Heat/thermal Electrical Chemical Mechanical: potential kinetic Sound 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. Objects vibratemaking noise. Plants grow. / Lasers cut. Forms of Energy

    22. List 6 forms of energy and give an example for each energy Energy 1. 2. 3. 4. 5. 6. Examples

    23. 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.

    24. FEnergyStationstaions • 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?

    29. Concept Review: Forms of EnergyDiscovery Education Techbook 1. What is energy? Answer: Energy is the ability to work, including moving objects or making changes. 2. What are the forms of energy? Answer: They are light, mechanical, sound, heat, electricity, and chemical. 3. What forms of energy can be observed using our senses? Answer: We can sense energy when it is in the forms of motion, light, sound, and heat. 4. What are the invisible forms of energy? Answer: Invisible forms of energy are electricity, and chemical. We can see the things those forms of energy do.

    30. Concept Review: Forms of EnergyDiscovery Education Techbook 5. How is energy stored? Give examples. Answer: Energy can be stored in many different forms. Humans store energy in our bodies as chemical energy. When we use it, it becomes another form of energy. 6. What are some ways energy can be transformed from one form to another? Answer: Energy can be transformed from one form to another in many ways. Energy from moving water and air can cause a machine to turn. These machines can transform the motion energy into electrical energy.   7. How can wind and water be used to move things? Answer: Wind and water can move things like boats and balloons on their own. They can also be used to make electricity. Then the electricity can be used to make other things, like fans or cars, move. cars, move.
