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.

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...

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.

Video explains why the periodic table devised by Dmitri Mendeleev has endured and how it has predicted the existence of elements. [4:25] Followed by a short quiz and a list of additional resources to explore.

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

Learn all about the periodic table in this interactive tutorial.

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...

A description of the arrangement of elements on The Periodic Table based on electron configuration.

In this tutorial, students will investigate the arrangement of the Periodic Table by watching videos, completing interactive activities, and quizzes.
