Below are sample questions representative of the exercises included on this worksheet and related 4.30 Conductors and Insulators (Electric) skill assessments:

Problem 1Difficulty: Mastery
A class is building a mini lighthouse model with a bulb. They need a strip from the battery to the bulb base, a switch tab students can press, and a stand that keeps the wires apart. Which full material plan works best?
Arubber strip, copper switch tab, and aluminum stand
Bmetal strip, plastic switch tab, and wooden stand
Cfoam strip, brass switch tab, and steel stand
Dglass strip, iron switch tab, and metal stand
Solution & Explanation:The strip to the bulb base should be a conductor like metal. The switch tab touched by students and the stand that separates parts can be made from insulating materials like plastic and wood.
Problem 2Difficulty: Mastery
Why is it safer to touch the plastic-covered part of a jumper wire than the metal end when current is present?
APlastic is an insulator, so it helps keep current away from the hand.
BPlastic carries current faster than metal.
CPlastic turns electricity into magnets.
DPlastic makes the battery stronger.
Solution & Explanation:Plastic is an insulator, so it helps reduce current reaching the hand. The metal end is the conductor part.
Problem 3Difficulty: Mastery
After testing many materials in the same simple circuit, which question can the class answer best with its data?
AWhich material is the prettiest?
BWhich material was made first in history?
CWhich material smells the strongest?
DWhich materials allow current to flow in a simple circuit, and which do not?
Solution & Explanation:The test data show which materials allowed current to flow and which did not, so the class can classify conductors and insulators.
