CURRICULUM GUIDE
UNIT V. Electricity
Estimated Time Range
2-4 weeks
Content Standard
9.2
ENDURING UNDERSTANDINGS
The student will understand that:
1. The electrical force is a universal force that exists between any two
charged objects.
2. Moving electrical charges produce magnetic forces and moving magnets
can produce electrical force.
3. Electrical current can be transformed into light through the excitation of
electrons
SAMPLE ASSESSMENTS
Build a circuit to demonstrate the principals of electric motors and electric
generators, and include a model illustrating an energy transformation to drive
the generator. (Calculate the power you generate and how much it would cost
at typical $ rates.)
Build circuits to create an electromagnet.
Build a quiz game board. Students will generate ten questions and answers
and use simple circuits to identify the correct answer.
Take a survey of the electrical appliances in your bedroom and based on your
calculations, predict your electric bill based on wattage, usage and estimated
cost of electricity. How might you reduce your consumption of electricity by
ten percent?
ESSENTIAL QUESTIONS
1. What is the role of energy in our world?
2. How do science and technology affect the quality of our lives?
LEARNING OBJECTIVES
The student will be able to:
1. Calculate the voltage, current and resistance in a simple series circuit
using Ohm’s Law.
2. Describe and explain electric current, voltage, and resistance (Ohm’s
Law).
3. Explain factors that affect resistance.
4. Explain how voltage produces electric current.
5. Explain how electricity is used to produce heat and light in incandescent
bulbs and heating elements.
6. Describe the relationship between current and magnetism.
