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,...

[Free Registration/Login may be required to access all resource tools.] Students explore the history of the periodic table, and explain how the periodic table was originally organized, compared to the arrangement of the modern periodic...

[Free Registration/Login may be required to access all resource tools.] In this learning module, students will explore how the form of the periodic table is related to electron configurations, which in turn influences chemical reactivity.

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.

This lesson will explore the layout of the periodic table by defining different groups and categories of elements. It is 3 of 3 in the series titled "Periodic Table Organization."
