High schoolers describe how the mass of a radioactive isotope changes with time and the factors that affect the rate of radioactive decay. They write nuclear decay equations to represent natural transmutation. This activity is...

The University of the State of New York has designed a series of exams to be given to high schoolers. This chemistry exam is one of the most comprehensive and well-written that you will ever find. It consists of 84 questions in a variety...

In this atoms instructional activity, students review terms associated with atoms which includes isotopes, transmutation, and radioactive decay. This instructional activity has 11 short answer questions.

Students study the difference between types of ionizing radiation and how elements are transmuted. They determine that radiation is normal and surrounds us. They calculate the amounts of alpha, beta and gamma radiation emitted from a...

High schoolers explore the Chernobyl incident and the resulting environmental health impacts. They explore three different isotopes that were released into the atmosphere. Through inquiry, students determine the difference between...

Referring to the periodic table of elements, nuclear physics learners determine the resulting elements of alpha and beta decay. Answers are given in atomic notation, showing the atomic symbol, mass, atomic number, and emission particles....

As an atomic structure reference and review tool, this handout fits the bill. The first page provides definitions and tables of orbitals, electrons, and energy levels. The second page is an opportunity to practice determining numbers of...

In this writing nuclear reactions worksheet, high schoolers read about nuclear equations for alpha decay, beta decay and positron emission. They are given the rules for writing nuclear reactions and a sample problem.

In this nuclear chemistry worksheet, students solve nine decay problems. They determine what forms in each problem given the radioactive element.

[Free Registration/Login may be required to access all resource tools.] In this module, students will explore the radioactive decay process in terms of balanced nuclear equations to discover the concept of half-life.

The Nobel Foundation provides this site about Niels Bohr's contributions to the world of physics, specifically his "investigation of the structure of atoms and of the radiation emanating from them." This biography includes information on...

At this site read about Ernest Rutherford (1871-1937 CE), the scientist who was awarded the Nobel Prize in Chemistry, "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances." This...

This is the story of the careers of Jean Frederic Joliot and Irene Curie.

An important visual theme in many ancient American art styles is that of transformation: one thing changing into another. Most shamans have spirit alter egos who help them in this world and in the spirit world, and these alter egos are...

Site provides the ABC's of nuclear science including radioactivity and gamma decay to fission and comic rays.
