Tutorial Review

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

Which procedure would most likely allow the bulbs to light?

• Open the switch and then connect the two wire that are attached to the wood block

• Switch the positions of the two wires that are connected to the battery and then open the switch

• Move the switch closer in the circuit to the battery

• Connect the two wires that are attached to the wood blocl

A group of students built the circuit shown below. The lightbulb does not glow. WHich statement explains this observaiton?

• The battery is not charged

• The lightbulb is not part of a complete circuit

• The circuit does not have a switch

• The bell uses most of the energy from the battery

Which circuit is a closed circuit if the switchi s closed?

• 
• 
• 
• 

A student puts four objects in a bucket filled with water. the objects are listed below.
∎Plastic ball
∎Glass Marble
∎Metal paper clip
∎Wood block
Which two objects are most likely less dense than water?

• Wood block and metal paper clip
• Plastic ball and glass marble
• Metal paper clip and glass marble
• Wood block and plastic ball

Students are asked to create a system using two mirrors and a flashlight to hit a target with a beam of light. Which diagram correctly uses the two mirrors and the flashlight to hit the target?

• A
• B
• C
• D

The diagram shows an electric circuit with four bells that a student plans to build.

When the student connects the wires as shown, which of the bells will ring?

This circuit has five light-emitting diode, or LED, lights. It also has one battery and one switch.

Which LEDs produce light when the switch is in the position shown?

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

Select the lights that will be on.

In some circuits that are used for decorating, one burned-out lightbulb will prevent all the other lightbulbs from lighting. In other circuits, one burned-out lightbulb will have no effect on the other lightbulbs.

In which of these circuits will the other lightbulbs still light even if one bulb is burned out?
