Learning Intention: Students will be able to distinguish between current and voltage and know how they are both measured. They will be able to describe the components of an electrical circuit (switches, loads, resistors, capacitors, cells, insulators and conducting wires) and how they work. Students will be able to construct simple series and parallel circuits and add ammeters and voltmeters to measure current and potential difference. They will understand the relationships between power, energy and time and describe in quantitative terms the relationship between current, resistance and voltage in a variety of electric circuits.
Success Criteria: Students will build a variety of series and parallel circuits and draw their corresponding circuit diagrams. They will perform a variety of practical experiments to measure voltage and current and calculate resistance. They will be able to describe circuits and how they operate using the correct terminology.
This online game, ElectroCity, is a great way to learn about energy, sustainability and environmental management. As the city mayor, you make decisions about the construction of electricity generation plants (coal, gas, solar, nuclear, wind or ocean?) and where residential and industrial development occurs. If you play the game, add the code BG28135 so I can track your progress.
Students will understand that current is measured in amps using and ammeter and voltage is measured in volts using a voltmeter. They will understand that when a circuit is connected in series:
* voltages add up for components
* currents are the same through all components
When a circuit is connected in parallel:
* voltages are the same across all components
* currents add up for components
You will be able to connect a simple circuit with a power source and globes in series and in parallel, and measure the current and voltage at different points on the circuit. You will complete the measurements of current and voltage that show the differences between series and parallel circuits.
