Rub the plastic ruler or comb vigorously against the woolen item for 15–20 seconds. This creates a net negative charge.
Scientific Investigation: Static Electricity Spinning Paper Experiment 1. Introduction and Objective Download Static Activity
When the plastic ruler is rubbed against the wool, electrons are transferred from the wool to the plastic, causing the ruler to become negatively charged (static charge). When this negatively charged object is brought near the electrically neutral paper, it repels the electrons on the surface of the paper, creating a positive charge on the side closest to the ruler. This phenomenon is known as . The electrostatic attraction between the negative ruler and the positive side of the paper creates a force sufficient to make the paper spin. 5. Extension Activities and Variations Rub the plastic ruler or comb vigorously against
Conduct the experiment in a dry room, as moisture in the air causes the static charge to dissipate more quickly. To make this paper even more detailed, I can: Introduction and Objective When the plastic ruler is
Bring the charged ruler near one edge of the paper (but do not touch it). The paper will begin to spin towards the ruler. 4. Scientific Explanation (Why it works)
This paper outlines a foundational STEM activity exploring static electricity through a "Spinning Static Paper" experiment. This hands-on activity demonstrates electron transfer (friction) causing charge separation in insulators.
Fold the paper square diagonally in both directions, then unfold it, creating a small, raised center point.
