  Simulation: Isotopes & Calculating Average Atomic Mass Mark as Favorite (75 Favorites)

  In the May 2017 simulation, students first learn how the average atomic mass is determined through a tutorial based on the isotope abundance for Carbon. Students will then interact within a workspace where they will select the number of isotopes, the mass of each isotope as well as their abundancies in order to successfully build a mystery element. Finally they will use their choices to calculate the average atomic mass of the mystery element.

  Simulation: Ionic & Covalent Bonding Mark as Favorite (168 Favorites)

  In the September 2016 simulation, students investigate both ionic and covalent bonding. Students will have the opportunity to interact with many possible combinations of atoms and will be tasked with determining the type of bond and the number of atom needed to form each. Students will become familiar with the molecular formula, as well as the naming system for each type of bond and geometric shape, when applicable.

  Periodic Table, Review, Elements, Subatomic Particles, Model of the Atom, Atomic Mass | Elementary School, Middle School

  Activity: Periodic Table Challenge Game Mark as Favorite (24 Favorites)

  In this activity, students will play an online game that quizzes their knowledge about the atomic structure of the first 20 elements on the periodic table. Students will be asked to identify different elements based on information related to subatomic particles, placement on the periodic table or from a provided Bohr model. This game has several options for students to choose from, and can be used to review content, or as a formative assessment.

  Project: Atomic Holiday Ornaments Mark as Favorite (41 Favorites)

  In this project, students will design an atomic holiday ornament for a chosen element, along with a certificate of authenticity to display on a “Chemis-tree”. Students will also have the opportunity to vote on the ornaments created by their classmates.

  Demonstration: Electrons and Ions Explained with Balloons Mark as Favorite (27 Favorites)

  In this demonstration, helium balloons and clothespin weights are used to demonstrate how adding an electron makes a negative ion, and removing an electron makes a positive ion, a concept that is often confusing to students.

  Subatomic Particles, Model of the Atom, Elements, Molecular Formula | Middle School, Elementary School

  Project: What's It Made Of? Mark as Favorite (15 Favorites)

  In this project each student will conduct research to discover what compounds, molecules, and elements make up a basic everyday object of their choice. The student will create a poster detailing what the object is made of, including a Bohr model. The student will also create a question about their object’s atomic structure for their peers as part of a culminating project gallery walk to observe, discuss, and learn about each poster.

  Video: Ernest Rutherford Video Mark as Favorite (72 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.

  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.
