Alpha/Beta/Gamma Decay, Radiation, Radioactive Isotopes, Isotopes  High School
Activity: Nuclear Decay Investigation
In this activity, students will explore different types of radioactive decay using a decay chain. Through modeling and analyzing a decay chain, students will familiarize themselves with different isotopes, and begin to understand how decay affects the nucleus of an atom.

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.

Radiation, Radioactive Isotopes, Alpha/Beta/Gamma Decay  High School
Activity: Case Study: The Lung Cancer Mystery
In this activity, students will analyze a scenario about the sudden spike of lung cancer cases in a specific neighborhood. They will take on the role of an investigative reporter in order to examine important information related to the crisis. The activity will provide students the opportunity to learn about radon gas, radiation and radioactive isotopes. The activity will culminate with the creation of a poster in the form of a public service announcement, where students will focus on the decay of radon and bring awareness to the hazardous radiation that is emitted.

Isotopes, Atoms, Electrons, Subatomic Particles, Elements, History, Introduction, Review, Alpha/Beta/Gamma Decay, Radioactive Isotopes  Middle School, High School
Activity: What are Isotopes? Video Questions
In this lesson, students will watch a video and answer questions about isotopes. They will learn about the discovery of isotopes, the difference between chemical and nuclear reactions, different kinds of radioactive decay, and some uses of radioactive isotopes.

Alpha/Beta/Gamma Decay, Half Lives, Radiation, Radioactive Isotopes, Isotopes, Atomic Mass, Subatomic Particles  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

Isotopes, Atoms, Subatomic Particles, Alpha/Beta/Gamma Decay, Radioactive Isotopes  High School
Activity: Using Stable Isotopes to Determine Material Origin
In this lesson, students will review the concept of isotopes and apply the concepts of stability and relative abundance in order to determine the recent travels of a person of interest in a criminal investigation.

Periodic Table, History, Radioactive Isotopes, Alpha/Beta/Gamma Decay  Elementary School, Middle School, High School
Video: Helium Video
In this video, Sam Kean tells stories about helium.

Radiation, Alpha/Beta/Gamma Decay, Graphing, Scientific Method, Experimental Design  High School
Lab: Alpha Beta Gamma Radiation
In this lab, students will investigate properties of three types of ionizing radiation—alpha, beta and gamma radiation. Students will have the opportunity to design their own procedures to explore the relationship between distance and radiation intensity.
