Subtitle

2. Agenda Presentation 1: Misconceptions MI Activity
Show you how you can teach electricity with $5 or less

3. Can I Power a Clock using a Potato?

5. Science and math may be theoretical and applied
It is a body of knowledge but it also doing, applying and experimenting to develop conceptual understanding and process skills.

6. Eliciting Misconceptions (Gooding & Metz, 2011)
Call for clarification (ask students to further explain, rephrase, illustrate, or demonstrate)
Call for evidence (seek substantiation for student claims)
Call for evaluation (ask students to speculate beyond the collected data)
Wait time I and wait time II (nonverbal tactics that allow students to extend their responses and encourage student-to-student discussion)
Play devil’s advocate (provide opportunities for students to present and defend their data-based decisions)

8. Specific Expectations
2.1 - follow established safety procedures for working with electricity.
2.2 - design and build series and parallel circuits, draw labelled diagrams identifying the components used in each, and describe the role of each component in the circuit.

9. Specific Expectations
2.3 - use scientific/experimentation skills to investigate electricity.
2.4 - design, build, and test a device that produces electricity – potato clock

10. Specific Expectations
2.5 - use technological problem-solving skills to design, build, and test a device that transforms electrical energy into another form of energy in order to perform a function

11. Specific Expectations
2.6 - use appropriate science and technology vocabulary, including current, battery, circuit, transform, static, electrostatic, and energy, in oral and written communication
2.7 - use a variety of forms to communicate

12. Specific Expectations
3.1 - distinguish between current and static electricity
3.3 - identify materials that are good conductors of electricity

13. Specific Expectations
3.4 - describe how various forms of energy can be transformed into electrical energy
3.5 - identify ways in which electrical energy is transformed into other forms of energy

14. Specific Expectations
3.6 - explain the function of components of a simple electrical circuit
3.7 - describe series circuits and parallel circuits, and identify where each is used
3.8 – describe ways in which the use of electricity by society has changed over time

15. Specific Expectations
1.1 assess the short and long term environment effects of different ways in which electricity is generated in Canada
1.2 assess opportunities for reducing electricity consumption that could affect the use of non-renewable resources in a positive way or reduce the impact on the environment

18. Select a group to describe how a battery works
Interpersonal: prepare a presentation –
Musical: prepare a song
Verbal Linguistic: prepare a poem or mnemonic
Spatial: create a poster
Mathematical: Create an outline of the process
Intrapersonal: research, record and create an independent representation- try online self publishing tool e.g., glogster, picktochart.com
Kinesthetic: prepare a model

19. Explain how a battery works Include the following vocabulary:
Electrons
Flow
Positive
Negative
Electrolyte
Circuit
metal

21. What is Electricity?
oxygen
The flow of electrons (e are moving!)

22. Battery
The reaction in the anode produces a build up of electrons, and the reaction in the cathode absorbs them. The net product is electricity.

23. Background Info Volts and Voltage
Voltage is a measure of the potential difference of the circuit measured in volts
Measured using a voltmeter
It is the difference in the ability of the two metals to attract electrons. The bigger the difference, the bigger the voltage.

24. Background Info Volts and Voltage
In a potato clock using copper and zinc as the electrodes, the difference is 1.34 V
Potato Clock

25. Background Info Amperes and Current
Current is the flow of electrons through the circuit, measured in amps.
Measured using an ammeter

26. Background Info Ohms and resistance
Resistance is how hard it is for the electrons to move through the circuit.
Measured using a multimeter
Depends on length of wire, cross-sectional area, type of material and the temperature

27. Background Info Current vs Static
This form of electricity exists when charges are able to constantly flow. As opposed to static electricity where charges gather and remain at rest, current electricity is dynamic, charges are always on the move.

28. $5 Obtain a battery, wire, and light bulb
Move through the electricity booklet.
The activities allow students to explore circuits
Please complete pages 1-5
