Watch budding chemists interact with the resource on chemical interactions. In the unit, six lessons provide an overview of basic chemistry, from understanding the development of atomic theory to distinguishing between ionic and covalent...

Discover how the periodic table tells the story of its elements. Learners begin by studying the makeup of several mixtures. Their analysis leads to a discussion of elements and the periodic table. As they dig deeper, they understand the...

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

From molecules to nanotubes, an engaging unit explores the world of tiny science. Fifteen hands-on experiments and lessons engage young scientists as they learn chemistry. Discussions, worksheets, and data analysis reinforce the concepts...

Students discuss the mass-energy relationship based on Einstein's work. They calculate the energy released in various scenerios and sketch diagrams for the Lyman, Balmer and Pfund Series. In groups, they discuss the role of photons and...

This lesson focuses on atoms and elements including what they are, the chemical symbols for elements, and the placement of elements on the periodic table. A link to a test is provided.

Learn how atoms are the building blocks of all living and nonliving things.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorail students will learn how to express the arrangement of electrons in atoms through electron configurations and Lewis valence electron...

Produce light by bombarding atoms with electrons. See how the characteristic spectra of different elements are produced, and configure your own element's energy states to produce light of different colors.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will sse the Periodic Table to identify and explain the properties of chemical families, including alkali metals, alkaline...

Through a series of slide show presentations and a video lesson, strengthen your understanding of valence electrons. [2:46]

The number of protons in the atom of an element determines its place in the Periodic Table. The number of electrons in an atom is the same as the number of protons. These electrons are arranged in shells or 'energy levels' around the...

This lesson focuses on early ideas about the structure of an atom including John Dalton's plum pudding model and Ernest Rutherford's nuclear model. A link to a test is provided.

When two or more atoms combine they give rise to a molecule. A molecule can be made up of many atoms of the same element. There are 112 elements known to man, so can you imagine the different permutations and combinations of molecules...

1HNMR theory begins in the nucleus of hydrogen. Complete this tutorial on the 1HNMR spectrum graph to learn about the number of equivalent hydrogens, b) the chemical environment of each hydrogen type and c) the number of neighbouring...
