Quiz on Circuits

The circuits below have LED bulbs. Which circuit shown will produce light when the switch is closed?

• A

• B

• C

The circuit below has two bulbs. Which procedure will result in only Bulb 2 operating?

• Switch X: Leave open, Switch Y: Leave open, Switch Z: Close it

• Switch X: Close it, Switch Y: Close it, Switch Z: Leave open

Look at the circuit below. The Bell and Red bulb are on. The Blue bulb and Green bulb are off. Which change can be made and still keep the Blue bulb and Green bulb off?

• Add a wire between Green bulb and the battery.

• Remove Wire 5.

• Move Wire 4 to the other side of the Blue bulb.

• Connect Wire 1 to the Blue bulb instead of the Bell.

Students built the circuit below. The students want the buzzer to produce sound, the bulbs to be on, and the motors to spin. Which switches need to be closed to make all the parts of the circuit work?

• Switch 2 and switch 4

• Switch 1 and switch 3

• Switch 1 and switch 2

The circuit below does not work. What TWO procedures would most likely allow the bulbs to light? Read the question carefully. Then enter your answers in the box provided.

• Change the wood block out for a metal object

• Take apart the circuit

• Change the wood block out for a closed switch.

• Change the wood for a open circuit

Students were investigating light with flashlights and lasers. Which statement supports the property of light being represented by the investigations?

• Light is being reflected.

• Light is being refracted.

• Light is being absorbed.

• Light travels in straight lines.

Students were asked to explain how the images on the water appeared. Which student gave the best reasoning?

• The Sun’s light rays strike the surface and get absorbed.

• Light from the Sun passes through the water and refracts.

• Light rays travel in straight lines and never change direction.

• Light from the sun is bouncing off the surface of the water.

What does the picture demonstrate about light?

• Y demonstrates refraction and X demonstrates reflection.

• W and X both demonstrate transmitted light.

• Y demonstrates reflection and X demonstrates refraction.

• X and Y both demonstrate light being absorbed.

For a class demonstration a student turned off the lights in the classroom. The student then shined a flashlight at a mirror. The light bounced off the mirror and hit the blank wall on the other side of the room. The light did not continue to travel through the wall because-

• The light cannot travel very far

• The mirror reflected all the light and it did not make it to the wall

• The light curved into the wall from the air

• The light was absorbed by the wall

A teacher gave her students a box filled with a wooden ramp, 4 books, a toy car, a piece of carpet, a piece of aluminum foil, a piece of sandpaper, and a meter stick. The students were asked to use their materials to design an experimental investigation that would answer which of the following questions?

• How does friction affect the distance the car will travel?

• How does the mass affect the magnetism of the objects?

• How fast does the car travel down the ramp?

• How will force affect the mass of the toy car?
