5.6B Electrical Circuits

In which of the following circuits will the buzzer sound?

• 
• 
• 
• 

Which of the objects below is NOT needed to test electrical conductivity?

• Battery

• Object powered by electricity

• Insulated wire

• Electrical tape

A student builds a working circuit with wires, a bulb, a battery, and a switch.

Which of the materials used by the student is the energy source for the circuit?

Write your answer in the space.

(a)  

Which of these could be used to replace a wire in a circuit?

Select TWO correct answers

• Iron nail

• Bendable straw

• Craft stick

• Aluminum foil

• Rubber band

Electricity can be used to produce -

• light

• heat

• sound

• all of the above

What is wrong with the circuit below?

• The light is not big enough

• It needs more wires

• The wires are not closed

• Another energy source is needed

Electricity can seriously harm people. Adults and students should be aware of electrical safety advice to avoid such things as electric shock. Which of the following is considered the most vital piece of advice to follow when exploring electrical circuits?

• Always follow the teacher's directions

• Always use new wire when building circuits

• Always put materials away after building circuits

• Always take the advice of your group members

Students are given materials to complete a circuit to turn on one light. The materials include two wires, one AA battery, and various sizes of lightbulbs. What is the variable in the investigation?

• Wires

• Battery

• Size of lightbulb

• Time of day

After several attempts to turn on a light using a simple circuit, a student concludes that the circuit must be closed in order for the light to turn on. Is the student's conclusion reasonable?

• No, because circuit cannot turn on lights

• No, because the circuit needs to remain open in order for it to work

• Yes, because all conclusions are correct

• Yes, because circuits must be closed in order for the electricity to flow through them

Which three materials could be used to create a working electricity circuit?

Select THREE correct answers.
