Materials:

-Stretched string -Metal washers -Small plastic beads -Nylon sheets -Magnets

Introduction:

In this lesson, we will be exploring the particle theory using different materials. This theory states that all matter is made up of tiny particles. We will be demonstrating this theory by using the materials provided and seeing the different results when they interact.

Procedure:

1. Tie one end of the string around a metal washer and the other around a plastic bead.
2. Hang the string from the edge of a table and place the nylon sheet underneath.
3. Hold a magnet above the plastic bead and watch what happens.

Observations:

When the magnet is held above the plastic bead, it will move toward the magnet, demonstrating the attraction between like particles. The metal washer will remain stationary, as it is not attracted by the magnet.

Conclusion:

This experiment shows how particles interact with each other. The metal washer was not attracted to the magnet, while the plastic bead was, demonstrating that different types of particles behave differently when interacting with electromagnets. This supports the particle theory, which states that all matter is made up of tiny particles.
