Determine the mass of two different isotopes of an element based on their deflection by a magnetic field.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will identify three methods for measuring the amount of matter in a sample. They will define the mole and its relationship...

A chemistry tutorial highlighting historical development of the atomic theory of matter and the periodic table of elements.

Analyzes the moral problem that some people may have if they are asked to work on a weapon of mass destruction even if it is legal. Learners will absorb all of the information given and decide what opinion they would have on the issue....

Students use the water-displacement method to find the volume of different rods that all have the same mass.

[Free Registration/Login Required] Put the elements in the correct order on the table by using the information given in each of the element squares.

An introduction to the mole, a unit of measurement that quantifies atoms and molecules.

Dutch version of the well-known "Particle Adventure" physics website that teaches students about atoms, mass, particle physics, and quantum physics. The site discusses theories related to physics and provides other links related to the...

Using a Periodic table with a list of atomic weights for reference, practice figuring moles of 103 elements.

For this lesson, students examine the impact of weapons of mass destruction, e.g., the atomic bombs dropped on Japan in World War II. They look at nuclear proliferation and treaties, and debate the pros and cons of nuclear weapons.

Learn how to calculate the kinetic energy of a gas molecule, describe the relationship between the temperature of a gas and the kinetic energy of atoms and molecule, and describe the distribution of speeds of molecules in a gas. The...

Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test how the ideas work!

J. Robert Oppenheimer is credited with the creation of the atomic bomb. But, "The country asked him to do something and he did it brilliantly, and they repaid him for the tremendous job he did by breaking him." This documentary traces...
