In the diagram, which object gained electrons, Jun?
- Neither of them
- The balloon
- The wool cloth
4.
In the diagram, what charge does the wool cloth have, Kira?
Use the picture in question 3.
- Negative
- No charge
- Positive

In the diagram, what is the total charge of the balloon and cloth together, Luz?
Use the picture in question 3.
- 6 minus
- 12 plus
- Zero

Is a copper wire a conductor, an insulator or a semiconductor, Milo?
- Conductor
- Semiconductor
- Insulator

Is a plastic comb a conductor, an insulator or a semiconductor, Noah?
- Semiconductor
- Insulator
- Conductor
8.
Is pure silicon a conductor, an insulator or a semiconductor, Pia?
- Semiconductor
- Conductor
- Insulator
9.
A negative balloon is held near the positive wool cloth. What happens, Tala?
- They trade places
- They push apart
- They pull together
10.
Why does a charged balloon stick to a wall that has no overall charge, Zee?
- It shifts the wall's charges, so the near side attracts it
- Air pushes the balloon onto the wall
- The wall is negative

Charge, conductors, insulators and semiconductors. Every version has 10 questions, and the answer key prints on the second page.

I can explain that charge is conserved. I can count it before and after rubbing, touching (identical spheres share equally) and touching in turn.
I can say that electrons move in charging and protons stay, and find the number of extra electrons from a charge, n = Q ÷ e.
I can sort conductors (copper, aluminum), insulators (glass, rubber, plastic) and semiconductors (silicon). I know silicon is used in chips and diodes, and that doping changes how it conducts.
I can explain like and unlike forces, induced charge (a balloon on a wall, a can near a dome), and a Van de Graaff's spreading charge and small sparks, as objects only.

Standard: none (TX, FL)

conductor: A material that lets charge move through it easily

insulator: A material that holds charge in place

semiconductor: A material, like silicon, that conducts in between

induction: Shifting charges in an object by bringing a charge near

conservation of charge: Total charge before = total charge after

Your child ignored the minus sign. Positive and negative charges cancel when they share, so add with signs.

Your child multiplied by e. The number of electrons is the charge divided by the charge on one electron.

Your child averaged all three at once. The spheres touch in turn, so share between A and B first, then between B and C.

What is the most common mistake with charge, conductors, insulators and semiconductors?

Your child ignored the minus sign. Positive and negative charges cancel when they share, so add with signs.
