A student drew a plan that they will use to build a simple circuit.

Using data from the plan, what will the student conclude when they build the circuit?

The light bulb will not light up since it is an open circuit.

Which image shows a human harnessed electricity?

1 & 2

A student observes the model of a simple circuit with a switch. He notices the light bulb is not lit.

What conclusion can the student make?

The switch is in the open position not allowing the electrical current to flow, causing the light bulb to not be lit.

A student collected materials and wants to figure out which group are insulators and which group are conductors.

A student would like to determine which of the materials in the boxes below would make a good switch to use in his circuit below.

How would he test each of the materials to determine if they were a good conductor or insulator? Describe the way a student should test the materials and tell what would make a good switch.

The student would place each material in the gap between the two wires. If the lightbulb turns on, then electricity flows meaning it is a conductor. If the lightbulb does not turn on, then electricity does not flow meaning it is an insulator.

A student turns on a computer to do homework. He then walks across the carpet and touches the metal chair to see a flash of light and feel a shock. What is an example of current electricity?

The computer turning on is an example of current electricity.

A student learns about simple circuits at school and would like to show his parents how they work. What components should he use to construct his model?

wire, lightbulb, battery

A student is problem solving why a classmate’s electrical circuit project is not lighting a bulb. They both notice that there is a gap in the wiring but there is not enough wire to complete the circuit. What could the students do to fix the problem?

A.  Place an eraser in the space.

B. Change the light bulb or battery.

C. Use a piece of string instead of the wire.

D. Place a paperclip between the wires in the gap.

Students construct a simple circuit and place an item in the gap.

Which of the following materials will conduct electricity?

A. Paperclip, nail, and penny

B. Paperclip, nail, and cardboard

C. Rubberband, paperclip, and nail

D. Rubberband, eraser, and cotton ball

A student is asked to group the statements from the box on the following chart about electricity.

Which statement would be correctly classified and why?

a. Lightning strikes a building does not belong on either chart.

b. Charging a cell phone and clothes sticking together in a dryer belongs on the static side because both are temporary.

c. Negative charges moving through a wire and charging a cell phone belong under current because they do not naturally occur and are created by humans.

d. A buildup of electrical charges on an object, clothes sticking together in a dryer belong under current because they have charges that move around.

A student documented different examples of electricity found outside.

The student claims that all three examples are naturally occurring electricity. Which of the following arguments BEST explains why the student’s claim is correct or incorrect?

A. The student’s claim is correct; all three examples show naturally occurring examples because the flow of electrons are uncontrolled.

B. The student’s claim is correct; all three examples show naturally occurring examples such as wind, sun, and lightning, which all produce electricity.

C. The student’s claim is incorrect; example 1 and 2 show human harnessed electricity since humans have created tools to control electricity using the sun and wind.

D. The student’s claim is incorrect; example 2 and 3 show human harnessed electricity since humans have created tools to control electricity using the sun and clouds.

A student makes a chart of materials they will use to create a simple circuit. The student also writes the purpose of those materials in the circuit.

Students in the class look at the list and provide revisions to the chart. Which student makes the correct revision?

Student A: The purpose for the lightbulb is to conduct electricity, not power the circuit.

Student B: The purpose for the wire is to turn the circuit on and off, not to conduct electricity.

Student C: The purpose for the switch is to power the circuit, not to turn the circuit on and off.

Student D: The purpose for the battery is to power the circuit, not to be powered by the circuit.
