  • Atomic Mass, Atomic Theory, Model of the Atom, Subatomic Particles, Periodic Table, History | Elementary School, Middle School, High School

    Access is an AACT member benefit. Video: Dimitri Mendeleev Video Mark as Favorite (69 Favorites)

    This video tells the story of how Dimitri Mendeleev organized the periodic table, even leaving gaps to be filled in with elements that weren't yet discovered.

  • Radioactive Isotopes, History, Subatomic Particles, Model of the Atom, Atomic Theory | Middle School, High School

    Access is an AACT member benefit. Video: Ernest Rutherford Video Mark as Favorite (71 Favorites)

    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.

  • Atomic Theory, Electrons, Model of the Atom, Subatomic Particles, History | Elementary School, Middle School, High School

    Access is an AACT member benefit. Video: Niels Bohr Video Mark as Favorite (69 Favorites)

    This video tells the story of Niels Bohr, a great scientist who redefined how we think about atoms and the electron. Bohr’s model of the atom helped to advance understanding of subatomic particles, and holds an important place in the history and development of the atomic theory.

  • Subatomic Particles, Model of the Atom, Atomic Mass, Electrons | Middle School, High School

    Access is an AACT member benefit. Project: Element Project Mark as Favorite (79 Favorites)

    In this project, students will become familiar with and have a workable understanding of atomic structure. The students will also create and construct a model of an atom.

  • Atomic Theory, History, Interdisciplinary, Culminating Project, Model of the Atom | High School, Middle School

    Access is an AACT member benefit. Activity: Scientist Infographic Mark as Favorite (50 Favorites)

    In this activity, students will design and publish an infographic focused on a well-known scientist and their contribution to the development of the atomic model.

  • Model of the Atom, Periodic Table, Subatomic Particles, Electrons, Valence Electrons, Ions | High School, Middle School

    Access is an AACT member benefit. Lab: Sweet Model of the Atom Mark as Favorite (63 Favorites)

    In this lesson, students will use different candies to represent electrons, protons, and neutrons to gain a better understanding of atoms, ions, and isotopes.
