Explore and control the building blocks of atoms! Physical science superstars add and remove subatomic particles to create atoms and ions with an easy-to-use interactive. An alternate activity includes an assignment that focuses on the...

From hydrogen to ununoctium, this collection of videos has everything you need to begin teaching about the periodic table. Offering descriptions of each element and interesting experiments demonstrating their properties, this resource is...

An engaging activity enlightens young chemists in this lesson on atomic structure. They play musical chairs through a series of concentric circles that represent electon orbitals. A laundry basket in the middle holds the protons and...

Bold boxes present parts of the periodic table, with some of the contents conveniently missing. Beginning chemists fill in the blanks, which may include the atomic number, atomic mass, atomic symbol, or element name. Beneath each box...

Properties of atoms are no small thing. A thorough video lesson describes properties of atoms and how they relate to the makeup of the periodic table. Learners review the relationship between subatomic particles and discover the...

Amazing scientific discoveries do not require fancy equipment. An interesting video lesson describes the process historical scientists used to identify the order of elements based on X-ray spectra. Learners discover the complex studies...

Time to put the knowledge to the test! Young scholars take what they know about the periodic table and build their own from scratch. Using clues from 26 different elements, they place elements in a blank periodic table. The clues include...

Introduce your class to the most important table they will never dine on! From a larger playlist covering chemistry concepts comes a thorough walk through of the periodic table. The narrator details the structure of the table, how to use...

How do medical professionals use radiation without doing more harm than good? Budding nuclear chemists begin their study of all things radioactive with a video from the JFR Science playlist. Topics include differences between isotopes,...

Thanks to this game, teaching isotopes will never be the same. Physical science scholars work their way toward understanding isotopes in an entertaining game. Pupils play rummy in groups while practicing good sportsmanship and creating...

Discover the relationship between mass number, atomic number, and the makeup of the atom. The video instructor explains how to determine the number of each subatomic particle from the atomic and mass number. She demonstrates multiple...

Explore the design of the periodic table. The lesson instructor explains how the periodic table's structure predicts the properties of elements. The video includes a discussion of periods and families of elements.

Since an atom can't have a partial neutron, the atomic mass should always be a whole number, but it isn't! An interactive video lesson explains how the atomic mass number from the periodic table incorporates the isotopes of an element....

Discover the significance of the atomic number and mass number. A video lesson describes the relationship between the two numbers and the subatomic particles. The instructor leads several examples that use the two numbers to determine...

When scientists confirm new elements, do these elements always fit in on the periodic table where scientists expect? The second video in a series of 15 discusses how the elements are organized on the periodic table. The resource includes...

Historically, scientists had to be creative to study subatomic structure. Scholars step into their minds to recreate the procedure Rutherford used to create his atomic model. Learners identify the creative efforts of early scientists...

After discovering plutonium, Glenn Seaborg was given the opportunity to determine its periodic symbol. Rather than going with the obvious Pl, he went with Pu as a joke. The designation was approved and is now on every periodic table....

The International Union of Pure and Applied Chemistry (IUPAC) was formed in 1919 and was crucial for allowing scientists to discuss findings during the Cold War. A presentation offers an introduction to atomic structure including the...

If your pupils think Um is the element of confusion, this presentation on period trends can only help. It covers the patterns for atomic radii, ionization energy, and electronegativity across a period and down a group.
