• Another bulb

• An insulated wire

• Another switch

NGSS.4-PS3-2

A student constructs the circuit shown for a science demonstration. ---With the switches in these positions, which lights are on?

• All the lights

• Lights 1 and 2 only

• Lights 3 and 4 only

• None of the lights

A student builds a circuit allowing the lightbulbs to light, the buzzers to make sound, and the motors to turn.---Which two switches can be open and still allow all of the parts to work?

• Switches 1 and 3

• Switches 1 and 4

• Switches 2 and 3

• Switches 3 and 4

This circuit has three lightbulbs and a bell. ---Which procedure will result in only the blue lightbulbs operating?

• Close Switches 1 and 2 and leave Switch 3 open.

• Close Switch 3 and leave Switches 1 and 2 open.

• Close Switches 2 and 3 and leave Switch 1 open

• Close Switch 2 and leave Switches 1 and 3 open

NGSS.4-PS3-2

Students constructed a circuit using different-colored lightbulbs. ---What will happen if Switch 3 is closed and the other switches are left open?

• Only the white bulb will operate

• None of the bulbs will operate

• Only the white and yellow bulbs will operate

• Only the red and blue bulbs will operate

NGSS.MS-PS3-5

A student is looking directly at a lit nightlight through two different cardboard tubes as shown. ---Through which tube, if any, will the light be seen and why?

• The bent tube only because the light bounces off the sides of the tube and travels through the tube to the student's eye.

• The straight tube only because the light travels in a straight line directly to the student's eye.

• Both tubes because light travels equally well along straight and curved paths.

• Neither tube because both tubes absorb all of the light.
