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 following 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 circuits 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.
