1. Grade 4 Curriculum Support Specialists: Mary Tweedy Noreyda Casañas Dan Gangeri Instructional Science Supervisor: Dr. Millard Lightburn What is Energy? Big Idea 10: Forms of Energy

2. Benchmarks SC.4.P.10.1 Observe and describe some basic forms of energy, including light, heat, sound, electrical, and the energy of motion. SC.4.P.10.2 Investigate and describe that energy has the ability to cause motion or create change. SC.4.N.1.6 Keep records that describe observations made, carefully distinguishing actual observations from ideas and inferences about the observations. SC.4.N.2.1 Explain that science focuses solely on the natural world. Office of Academics - Department of Science

3. What do light, heat and motion have in common? They show Energy is all around us! – You can see energy as light from the sun or a lamp. – You can feel it as heat warms things up. – You can see motion energy every time you move.

4. You use energy when you: – Take a walk – Lift a book – Throw a ball How else do you use EnergyHow else do you use Energy? Office of Academics - Department of Science

5. 5 What is Energy?Energy Energy makes things happen. Energy is the ability to cause a change. Energy can change an object’s  Motion  Shape  Temperature  Color Energy is the Ability to Do Work Office of Academics - Department of Science

6. What is light ?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. Light Light travels in waves. Office of Academics - Department of Science

7. Following Light Light bounces off or is reflected from some kinds of opaque objects. Angles of Reflection Office of Academics - Department of Science

8. Compare and Contrast Cardboard VS A Mirror Light does not pass through  opaque  Dull  Dark  Absorbs light Light does not pass through  opaque  shiny  Smooth  Reflects light Office of Academics - Department of Science

9. Just Passing Through  Some objects let all light pass through them are known as: transparent  Some objects let some light pass through them are known as: translucent Office of Academics - Department of Science

10. 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: Office of Academics - Department of Science

11. 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 Office of Academics - Department of Science

12. What Color is Light? Write down responses on your note page.  Problem: What happens when we shine a flashlight on a CD?  Hypothesis:  Test and Observe:  Conclusion: Office of Academics - Department of Science

13. TAG Reflections Tell a fact you learned about light. Ask a question about something you don’t understand about light.light Give another idea that was addressed in our study of energy.

14. Mechanical Energy Mechanical energy is energy due to motion. Energy of motion is also known as kinetic energy. Office of Academics - Department of Science

15. What is HeatWhat is Heat Energy? Heat is movement of energy from one place to another. Temperature is a measure of heat energy. A thermometer is the tool used to measure temperature. Reading a Thermometer Every time energy changes form, it gives off some unusable heat. Office of Academics - Department of Science

16. What happens in Heat/Thermal Energy ?Thermal Energy Energy is the movement of the atoms in an object. Heat is the movement of energy from one place to another. When any form of matter gets warmer, the kinetic energy of its atoms increases. The object’s particles move faster, so its heat/thermal energy increases. A change in thermal energy can lead to a change in phase or state of matter: - Ice melts from a solid to a liquid. - Liquid water changes to water vapor. Office of Academics - Department of Science

17. How Does Heat Move?Heat Thermal Energy flows from warmer substances to cooler substances. Heat can be transferred from one object to another. Office of Academics - Department of Science

18. How Does Heat Move? Thermal energy flows from warmer substances to cooler substances. Heat is transferred from one object to another in three different ways: conduction convection radiation Office of Academics - Department of Science

19. What are the three methods of heat transfer ? Office of Academics - Department of Science ConvectionConduction Radiation

20. What is Electrical energy?Electrical A form of energy that is produced when electrons move from one place to another. Electrons are particles that are in the space around the nucleus of an atom. The forces of attraction and repulsion make electrons move. Try Exploring circuits.

Lights on. / Machines run. C. Matter vibrates. D. Plants grow. / Humans see E. Sled slides down the hill. Office of Academics - Department of Science

22. Concept Review: Forms of Energy 1. What is energy?energy Answer: Energy is the ability to cause motion, or make changes in an object. 2. What are the forms of energy? Answer: They are light, mechanical, sound, heat, and electricity.lightsoundheat 3. What forms of energy can be observed using our senses? Answer: We can see energy when it is in the forms of motion and light. We can hear sound and we can feel heat.
