Mississippi Science P.4.6A.2
The Standard
- P.4.6A
- Students will demonstrate an understanding of the common sources and uses of heat and electric energy and the materials used to transfer heat and electricity.
Plan and conduct scientific investigations to classify different materials as either an insulator or conductor of electricity.

What This Standard Means
What Students Need to Do
- Students build a battery-and-bulb circuit with a gap for a test item. They test one material at a time, keep the setup the same, and record whether the bulb lights.
What Mastery Looks Like
- Students can explain why only the test material should change. They use their results to sort materials into conductors and insulators, and retest a dark bulb before deciding.
Common Misconceptions
- Students may think every shiny object conducts and every dull object insulates. They may call a metal spoon an insulator when the bulb stays dark because a clip is loose.
How to Assess It
- Exit ticket: The bulb lights with foil but stays dark with a plastic ruler. Classify both materials and name one part of the setup you would keep the same.

Ways to Teach It
Connect a 2-AA pack and 3V bulb with clip leads, leaving a gap; bridge it with foil, a spoon, and a plastic ruler.
Ask: If the bulb stays dark when testing a spoon, what would you check before calling the spoon an insulator?
Give pairs cards showing bulb-lit and bulb-dark results for six materials; have them sort the cards and explain one choice.
Show an unplugged phone charger; have students identify its metal prongs and plastic casing, then explain why each material is used.
