I Love Science 5.6B

The diagram below shows a bulb and a wire attached to a battery. Why would this bulb be lit?

• The wire is wrapped to the bottom of the bulb that is a type of conductor.

• The wire is wrapped to the battery and that is why the bulb is glowing.

• The wire is wrapped to the glass and the glass is an insulator causing the light to grow

• The wire is wrapped to the bottom of the bulb with a metal case, a conductor which is touching the battery causing the light bulb to glow.

A group of students are building a circuit. The investigation is shown below. Which of the following statements correctly explains why the circuit is open?

• The bulb needs to be replaced in order to make it a closed circuit

• Switching one of the batteries so that the positive end connects to the other battery.

• The wires need to be attached to the battery not the battery holder

• Adding new batteries so that the electric current can flow through the wires.

Observe the circuit below. If the students connect a wire between bell 2 and bell 4, which of the bells will ring?

• Bells 1 and 3

• Bells 1 and 4

• Bells 1, 2, and 4

• Bells 1, 3, and 4

A group of students constructed the circuit with colored light bulbs. If switch 1 was closed which bulbs will glow

• The red and blue bulb will glow and the white will not glow

• The blue and white bulb will glow and the red will not glow

• All the bulbs will glow

• The red and white bulb will glow and the blue bulb will not glow

Students constructed the circuit above. What would the students have to do in order to make the bell ring?

• Close swtich 1 and 3, leave switch 2 open

• Close 2 and 3 and leave switch 1 open

• Replace switch 1 with a metal spoon and leave switch 2 and 3 open

• Close switch 3 and leave switch 1 and 2 open

If the blue bulbs were replaced with closed switches, and switch 3 was replaced with a rubber band which appliances will function?

• All the appliances will function

• The green bulb will be the only appliance to function

• The bell will be the only appliance to function

• None of the appliances will function

The student place different objects in the gap and turn on the switch to see if the light bulb lights up. Which object will best conduct electricity?

• A glass bead because it allows electricity to flow through

• A plastic button because it allows electricity to flow through

• A copper coin because it allows electricity to flow through

• A wooden toothpick because it allows electricity to flow through

A group of students are conducting an investigation on circuits. The circuit below illustrates two light bulbs, a power source, and copper wires. Which would happen to the circuit if the students added an additional power source?

• The light bulbs will shine brighter

• The light bulbs will dim

• The copper wires will not allow electricity to flow to the light bulbs

• The additional power source will only light up one light bulb.
