| 11 Questions
Note from the author:
Students will build a virtual electric circuit and answer questions.
1
1 pt
What do a light bulb, a toaster, a radio, and a computer all have in common?
2
1 pt
Suppose you connect a battery to a small light bulb with a single wire. What do you think will happen? Explain your answer.
The outlined content above was added from outside of Formative.

1 pt
Now try to light the bulb with the smallest number of components. Draw your ciruit in this space.

Based on what you have seen, what must be true for a circuit to light a bulb?
There has to be a lightbulb and conductor (wires).
There has to be an energy source (a battery).
There can't be any gaps in the path.
All of the above.
The outlined content above was added from outside of Formative.
What materials will CLOSE a circuit?
Conductors are materials with easily moveable charges, allowing current to occur.
Insulators do not have easily movable charges, so current is not produced.

Experiment: Drag each material into the gap of the open circuit you made. If the light bulb lights, the material is a conductor. If not, the material is an insulator. Keep track of your findings below.
