Marble electron run

Materials needed:

marble run obstacles (8)

marbles (10)

  1. Have children hold their marble-electron high and ask “does it want to go low?” repeat until children understand that it wants to flowdown
  2. Introduce the special pieces as ways to get the marble electrons to do different things, just like semiconductors in tablets and gadgets
  3. Rotate the obstacle pieces around the group or build one marble run together.

Note: There is also a water inflatable run where the water would be the “current” flow.

Why it works

An electron moves to the easiest location, where there is at less energy. That is just like a marble moving through a marble run to get to stop at the bottom.
