Re: [Electrical] Multimeter question

Hopefully the OP is aware that a 5th grader should not be testing line voltage even for a school project.

Yes, we're just testing resistance on non-electrified objects such as fruit, water, metals, wood, plastics. (we're testing on the obvious insulators such as plastic to show something that does not conduct a electricity)

Try a dark pencil (#2 wooden pencil would be more sure) line drawn on paper.

Try 2 people holding hands, and have each person grab a different probe tip. (highest resistance range).

Try a diode in the diode range. Note that temperature changes the reading.

Try a bipolar transistor. It works like two diodes but the collector-to-base will show less drop than emitter to base. Probably outside the scope of what you are doing.
