  1. Grade 5 Essential Lab # 7 Get Connected Big Idea 10: Forms of EnergyBig Idea 11: Energy Transfer and Transformation Mary Tweedy, Curriculum Support Specialist Keisha Kidd, Curriculum Support Specialist Millard Lightburn, PhD, District Science Supervisor Division of Science

  2. Big Idea 10: Forms of Energy &Big Idea 11: Energy Transfer and Transformation 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. SC.5.P.11.1 - Investigate and illustrate the fact that the flow of electricity requires a closed circuit (a complete loop). SC.5.P.11.2 - Identify and classify materials that conduct electricity and materials that do not.

  3. Lesson Objectives: Students should be able to: Define electricity. Understand the role of electrons in electricity. Model the flow of electrons in a circuit. Build an actual electric circuit. Explain how to tell when the path of an electric circuit is complete. Test the conductivity of a variety of materials. Explain how electrical energy can be transformed into light, heat, sound and motion.

  4. What is Energy? Energy is the ability to do work. 4

  5. How do we use electricity? Electricity powers nearly every modern gadget, from refrigerators to smartphones. But do you know how electricity works? You'll find out how electricity keeps our daily lives flowing.

  6. What is electrical energy? 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. http://www.energyquest.ca.gov/story/chapter02.html

  7. Lab # 7: Get ConnectedHow does an electric circuit work? • Let’s look at some parts of a circuit. • What do you notice about the … bulb wire battery • What do you need to do to make a circuit to light the bulb?

  8. What do you need to do to make a circuit to light the bulb? Try it. = Now try it with two wire.

  9. Think about this…Lab # 7: Get ConnectedWrite your responses in your notebook. Is electricity flowing through the systems you built? How do you know? What do you think are necessary elements of all complete circuits? What kind of energy makes a battery work? Name the transfers of energy in the circuit you built. What are you wondering now?

  10. How do you think a battery works?Battery Power How does it work? A battery contains 2 different metals. Metals like all matter are made up of atoms. Atoms are made of protons, neutrons, and electrons. One of the metals in the battery wants to give up its electrons and the other metal wants to accept them. Connecting the wires, and the bulbs to a battery, gives the electrons a path to travel from one metal to another. Those traveling electrons are electricity.

  11. How is either of the circuit models you built similar to a flashlight’s circuit? How does a flashlight work? When the switch of a flashlight is pushed into the ON position, it makes contact between two contact strips, which begin a flow of electricity, powered from the battery. The batteries rest atop a small spring that is connected to a contact strip. The contact strip runs down the length of the battery case and makes contact with one side of the switch. There is another flat contact strip on the other side of the switch, which runs to the lamp (light bulb), providing an electrical connection. There is another part connected to the lamp that makes contact with the positive electrode of the top battery, thus completing the circuit to the lamp and completing the generation of electricity.

  12. Lab # 7: Get Connected Activity #2 How should you connect the materials you have to make a path to test the flow of electricity? Make a plan with your group. Connect the parts to test your plan. Does the bulb light up? If not keep trying. Draw a picture of your working circuit. Show how the parts work.

  13. Activity #2Which common materials are good conductors for the flow of electricity?

  14. Looking Back Were your predictions correct? How do you know? How are the materials that conducted electricity allowing the bulb to light alike? Which material created the brightest bulb? What are you wondering now?

  15. Electrical Resources Electricity in our Lives Simple Circuits Building Circuits

  16. Parts of the Circuit and their Jobs • Source of current • Carries current • Turns circuit on and off • Changes electrical energy to light • Battery • Bulb • Switch • Wire • What does making a complete circuit mean? • Why are many wires coated with plastic?

  17. Electricity Project Ideas • Give a presentation • Act it out • Write a story about… • wasting energy daily. • loosing electricity for one week. • realizing that conserving energy helps the entire community. • Create a model • Write a report or an essay • Compose a song • Make a poster

  18. Writing Prompts Make a Drawing with Labels Write to Explain A classmate is studying a cord that connects a lamp to a wall outlet. The classmate sees that the inside of the cord is made of metal wire, and that the outside of the cord is made of plastic. Explain why each of these materials is used in the cord. Create a drawing to include everything you would need to make a light-bulb light or a radio work. Label your drawing and use arrows to show the direction of the current. Describe how the circuit works.

  19. What is the Transfer of Energy? Energy can move from one object to another. < < light electrical chemical What does the energy of a lit light bulb change into after the flashlight has been on for a while? Heat Energy

  20. What can electrical energy be changed to? Gizmo Energy Conversions
