NGSS.4-PS3-2

A battery, bulb, wires, and a switch have been assembled as shown in the diagram. The bulb does not light

Which of the following changes would make the bulb light?

• use a larger battery

• change the wires

• close the switch

• replace the broken bulb

Students use an electrical circuit to test if different materials will conduct or insulate electricity. Which of the following materials is a conductor and will allow electricity to flow through the circuit?

• wood

• glass

• copper

• plastic

A student slid down a slide on a school playground on a hot summer day. The student noticed that the slide is made of plastic and not metal. The slide is made of plastic most likely because --

• plastic conducts thermal energy

• plastic insulates thermal energy

• plastic produces thermal energy

• plastic conducts thermal and electrical energy

Students used the circuit shown to test five different objects as conductors or insulators of electrical energy

Materials Tested: copper penny, iron nail, wooden cork, plastic straw, aluminum foil

• copper penny, iron nail, aluminum foil

• plastic straw, iron nail, aluminum foil

• copper penny, wooden cork, plastic straw

• iron nail, wooden cork, copper penny

Students were investigating the flow of electricity in the closed circuit shown

What would happen if the circuit was open at Point A (if the wire were cut)

• Bulb 1 would stay lit, and Bulbs 2 and 3 would go out

• Bulbs 1, 2, and 3 would stay lit

• Bulbs 1, 2, and 3 would go out

• Bulb 1 would go out, and Bulbs 2 and 3 would stay lit

Students illustrated the series circuit in their notebook

If the wire between light bulb 2 and light bulb 3 is cut, then --

• light bulbs 2 and 3 will not light and light bulb 1 will light up

• light bulbs 1 and 2 will light and light bulb 3 will not light up

• light bulbs 1 and 3 will light and light bulb 2 will not light up

• light bulbs 1, 2, and 3 will not light up

A pencil falls to the ground when it is dropped. Which force acts upon the pencil causing it to fall?

• friction

• magnetism

• motion

• gravity

Students were exploring the poles on two different magnets. When placed together the magnets pushed away from each other.

Which of the following best describes the effects of force on the magnets?

• the magnets push away because they are attracted to each other

• the magnets push away because they are repelling each other

• the magnets push away because the magnets have different strengths

• the magnets push away because they have lost their magnetic power

Students conduct an investigation by rolling a car down a ramp covered with four different surfaces. Students measure the time it takes for the car to travel from the top of the ramp to the bottom of the ramp. The results are shown in the graph.

Based on the chart, which surface causes the most friction?

• Surface 1

• Surface 2

• Surface 3

• Surface 4
