  Lesson Plan: Acting Out Atomic Structure

  In this lesson, students will model the location and behavior of protons, neutrons, and electrons that make up the structure of atoms, focusing on the first 18 elements on the periodic table. Students will model different elements first by adding protons and neutrons (colored balls) to make the nucleus (a basket). Then, the students themselves will represent the electrons that are always moving around the nucleus yet remaining within their designated energy level. This activity is easiest to complete outside or in a large open room to allow for enough room.

  Video: Ernest Rutherford Video

  Rutherford's initial research was studying alpha particles, which he hypothesized were helium nuclei. With the help of Hans Geiger, Rutherford conducted the gold foil experiment, which justifies that the nucleus of an atom is a dense collection of protons and contains the majority of an atom’s mass. It also inferred that most of the atom is empty space and electrons are not located in the nucleus. He won the Nobel Prize in chemistry in 1908 for his studies on radioactive substances.
