Half Lives, Alpha/Beta/Gamma Decay, Radioactive Isotopes  High School
Activity: Graphical Analysis of Nuclear Decay
In this activity, students analyze a series of graphs and data points to discover a pattern, and realize the meaning of a halflife. During this investigation, students will make connections between the concepts of nuclear decay, radiation and the Law of Conservation of Mass.

Periodic Table, Half Lives, Subatomic Particles, Radioactive Isotopes  High School
Activity: Why are Some Isotopes Radioactive?
In this activity, students use periodic trends and data to make predictions about what makes an isotope radioactive. They will then verify or refine their predictions using a PhET simulation.

Half Lives, Radioactive Isotopes  High School
Activity: Radioactive Decay and Seafloor Data
In this activity, students will apply their understanding of radioactive decay to analyze and interpret the meaning of Atlantic seafloor isotope data. Students will then use their results to suggest past changes that have occurred with the seafloor

Half Lives, Radioactive Isotopes  High School
Activity: Radioactive Decay and Peat Bogs
In this activity, students will apply their understanding of radioactive decay to establish that radiometric dating (specifically C14) can be used to reliably determine the age of Earth’s materials.

Half Lives, Radioactive Isotopes  High School
Activity: Investigating Exponential Decay
In this activity, students will learn about radioactivity, exponential decay, and halflife through two handson experiences.

Radiation, Half Lives, Isotopes, Alpha/Beta/Gamma Decay, Atomic Mass, Subatomic Particles, Radioactive Isotopes  High School
Activity: Radiological Applications of Isotopes
In this lesson, students will apply their knowledge of nuclear notation using trading cards to investigate and discuss the applications of isotopes in the medical field. The conclusion of the activity includes a summative assessment where students must advertise the radiological services using their knowledge of isotopes and their medical applications

Radiation, Half Lives, Radioactive Isotopes
Simulation: HalfLife Investigation
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 halflife.

Phase Changes, Radiation, Half Lives, Radioactive Isotopes  High School
Activity: Radioactive Dating: The Demise of Frosty
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 halflife. Students will be introduced to solving mathematical problems that involve halflife.

History, Model of the Atom, Radiation, Half Lives, Atomic Structure, Subatomic Particles, Radioactive Isotopes  Middle School, High School
Activity: Marie Curie Video Questions
In this activity, students will watch a short video and learn about Marie Curie, her Nobel Prizes, radiation experiments, and discovery of new elements.

Half Lives, Radioactive Isotopes  High School
Activity: Using Dice to Explore Radioactive Decay
In this activity, students will use dice to simulate the radioactive “decay” of samples of two different elements with two different halflives. 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 halflife of each element in the fictitious time units of “rounds”.

Radiation, Half Lives, Radioactive Isotopes  High School
Activity: Simulation Activity: HalfLife Investigation
In this 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 halflife.

History, Radiation, Half Lives, Radioactive Isotopes  Elementary School, Middle School, High School
Video: Marie Curie Video
This video tells the story about Marie Curie, including her Nobel Prizes, radiation experiments, and discovery of new elements. Irene Curie is also mentioned.

Half Lives  High School, Middle School
Lab: HalfLife
In this lab, students visualize the random nature of atomic decay (or first order chemical reactions) and also helps them realize the important difference between macroscale and microscale phenomena.

Half Lives, Graphing  High School
Lab: Twizzler HalfLife
In this lab, students will better understand the concept of halflives.
