1. Grade 6 Science Teacher: Ms. J. Lilly

2.  Electricity: The flow of electrical charge.

3.  taking electrical devices like radios into the bathroom or near the bath  fallen power lines  climbing transmission towers and climbing trees or flying kites near power lines  frayed or exposed wires  pulling out plugs by the cord  taking apart electrical appliances (some contain capacitors which store electrical charge even if unplugged)

4.  three prong plug

5.  circuit breakers

6.  Lightning Rod

7.  Fuses

8.  Electrical Safety Video Electrical Safety Video

9.  Create a chart or collage to illustrate electrical safety.

10. Before we go any further, we must have an understanding of the basic building block for all matter: the atom.  Atoms are extremely small and are made up of a few even smaller particles.

11. The basic particles that make up an atom are: electrons(negative charges), protons(positive charges), and neutrons(no charge). Protons and neutrons are found in the nucleus. Electrons are found orbiting outside the nucleus.

12.  Static Electricity: When electricity gathers in one place.  Works best when the air is dry!

13. What causes attraction and repulsion?

15. We see static electricity every day! For example:  When we rub our feet on the carpet and then zap something when we touch it. Example: John Travoltage  When our hair gets charged and sticks up

16.  Lightning

17.  Balloons  Fur  Fabrics  rubber rods  Styrofoam balls  bits of paper or confetti  and plastic combs.

18.  Which combination of materials when rubbed will pick up the most pieces of confetti or puffed rice?  Which combination of materials when rubbed will attract a hanging piece of yarn the most?  Can they get two identical objects to attract?  Can they get two identical objects to repel?  Can they get two different objects to attract?  Can they get two different objects to repel? Students should record their observations, measurements, and procedures. Be sure to identify the manipulated variable, responding variable and control variable.

19.  Manipulated Variable (variable you are changing)  Dependent Variable (responding variable)  Control Variable (things that we hold constant, so that our results are not affected by anything else)

20.  Current electricity: moving electricity  Use batteries, wires, and light bulbs to try to make a variety of circuit pathways

21. Rules: 1.Draw diagrams using a Ruler. 2.Make all connecting wires straight with 90 degree (right) angles. 3.Your finished drawing should be rectangular or square. 4.Do not cross over wires. 5.Keep in mind, electricity will flow from the negative end of the battery to the positive end.

22.  Here is a circuit diagram of a simple circuit with two light bulbs (load), wire, switch, and a battery. Actual CircuitCircuit Diagram

23.  In your exercise, draw a circuit diagram for each of the following: In which diagram will electricity flow? In which circuit will the electricity not flow?

24.  Conductors: made of materials that electricity can flow through easily. Examples: metal  Insulators: materials opposite of conductors and blocks the flow of electricity. Examples: glass, plastic, rubber

25.  Based on the information in the last slide, what materials would make a good switch in an electric circuit?

26.  Series Circuit: a circuit that has only one pathway that electrons can flow. When one bulb goes out, they all go out! Ex: Old Christmas Lights, flashlight Series Circuit

27.  Parallel circuit: A circuit that has many paths that electricity can flow.

29.  How is the static electricity on our clothes or in our hair different from the electricity that runs this clock (or some other appliance)?  Can we use static electricity to light the bulb in a series circuit?

30.  Remember: Current electricity is a charge (electrons) that can move along a closed path, while in the case of static electricity, the charge is localized on an object.  From home and school experiences, write about two examples each of static and current electricity and how each affects their daily life.

31.  Electromagnet: usually consist of a large number of closely spaced turns of wire that create the magnetic field. Electromagnet:

32.  Many devices use electromagnets (telephones, televisions, radios, doorbells, and microphones).  Pictures of heavy objects that are being lifted using electromagnets can be used to illustrate the power that they have.

33.  Identify and describe the uses of electricity in everyday life.  Pretend you live in the days before electricity. In their journal, write about your activities. Students should be sure to refer to activities for which we would use electricity today.

34.  The production of electricity by wrapping a magnet in wire has lead to the invention of electrical generators.

35. Forms of energy that can be converted into electrical energy are:  chemical (batteries/fossil fuel combustion)  mechanical (wind, falling water, steam)  solar energy Sources of energy would be wind, water, tidal, solar and nuclear. Renewable forms of energy would be wind, solar, water and tidal. Non renewable forms of energy are fossil fuels and nuclear energy.

36. o Kilowatt Hour o Watts o The more watts or kilowatt hours a device is rated for, then the more electrical energy is being used. o How can we reduce our electrical consumption? Develop strategies to conserve energy in the school. They should present their report to the administration.

37.  Choose either chemical, mechanical, or solar energy and research: a. how electrical energy is produced from the source b. whether the source is renewable or non- renewable c. positive and negative impacts on the environment of using this source to create electricity
