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...

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...

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...

Add a splash of color to your chemistry class! Science scholars discover the principles behind color through a wide variety of hands-on activities. Lessons include dyes, chromatography, and flame tests.

Show your class that trigonometric functions have characteristics of their own. A resource explores the features of trigonometric functions. Learners then connect those concepts to inverse trigonometric functions and trigonometric...

This assessment pair goes way beyond simple graphing, factoring and solving polynomial equations, really forcing learners to investigate the math ideas behind the calculations. Short and to-the-point questions build on one another,...

Students will discuss the de Brogile Hypothesis and state the circumstances under which the wave nature of matter is observed. They will also calculate the wavelengths of matter waves.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will begin to explain the use of chemical and physical properties in the historical development of the Periodic Table. They will be...

This learning module allows students to use the organization of the periodic table to understand the element and their properties. By the end of the activity, students will be able to locate metals, nonmetals, and metalloids and the...

Given descriptions, scenarios, or groups/series of elements, students will use the Periodic Table to relate the size of the atomic radii, electronegativity, and ionization energy of elements to their position on the chart. Students will...

Given descriptions or specific element groups, students will use a Periodic Table to relate properties of chemical families to position on the table.

The elements in Group 7 of the Periodic Table are called the halogens. They include chlorine, bromine and iodine. Learn about their properties and uses, then take a quiz.
