  Activity: Radioactive Dating: The Demise of Frosty Mark as Favorite (17 Favorites)

  In this activity students will investigate the idea that carbon dating is based on gathering evidence in the present and extrapolating it to the past. Students will use a simple graph to extrapolate data to its starting point and then pool the data to make a graph that simulates half-life. Students will be introduced to solving mathematical problems that involve half-life.

  Activity: Marie Curie Video Questions Mark as Favorite (5 Favorites)

  In this activity, students will watch a short video and learn about Marie Curie, her Nobel Prizes, radiation experiments, and discovery of new elements.

  Radioactive Isotopes, Half Lives | High School

  Activity: Using Dice to Explore Radioactive Decay Mark as Favorite (9 Favorites)

  In this activity, students will use dice to simulate the radioactive “decay” of samples of two different elements with two different half-lives. At the end of the simulation, all the groups will pool their data (by round) and then the class results will be graphed. The graphs will be analyzed to illustrate the process of radioactive decay and to determine the half-life of each element in the fictitious time units of “rounds”.

  Radioactive Isotopes, Atomic Theory, History, Pros Cons of Nuclear Power, Radiation, Subatomic Particles | Middle School, High School

  Activity: Lise Meitner Video Questions Mark as Favorite (7 Favorites)

  In this activity, students will complete a short series of questions as they watch the Founders of Chemistry video about Lise Meitner. The video tells the story of Lise Meitner, a pioneering female scientist in the field of nuclear chemistry, who was denied a Nobel Prize but has an Element named in her honor.

  Simulation: Half-Life Investigation Mark as Favorite (0 Favorites)

  In the March 2017 simulation, students will have the opportunity to investigate the decay of two samples of unstable atoms. Students will interact with the simulation in order to decay the unstable samples resulting in a visual and graphical interpretation of half-life.

  Video: Ernest Rutherford Video Mark as Favorite (28 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.
