The Connection Between Pigment and Light Colors

Through a station rotation activity, scientists complete 9 chemistry activities to complete this interactive worksheet. Concepts include molar masses, percent composition, accuracy vs. precision, mass of an object, scientific notation,...

General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific teacher...

Did you know light can decrease visibility? Light pollution absolutely makes it more difficult to see stars. Scholars build a simple magnitude reader to determine the magnitude of stars. They use these data to estimate the impact of...

Start stoichiometry scholars off on the path to success with a short video. The narrator of this interesting video guides viewers through the concepts of the mole, molar mass, and Avogadro's number. Additional topics include converting...

Why do leaves change color in the fall? The video explains the relationship between chlorophyll and light, connects the concepts of light to photosynthesis, relates the visible color spectrum to electromagnetic radiation. 

What do scientists do when their observations don't match the theory? An interesting video introduces the ultraviolet catastrophe as part of a larger series covering physics concepts. Starting with ultraviolet light and ending with...

Do your pupils already have knowledge of moles and mass? If so, this is the next step for the chemistry classroom. The video segment, while short in length, is filled with demonstrations on how to perform mole calculations involving both...

Though UV radiation can damage skin, it isn't all bad. The third installment in a six-part series allows the class to study the structure and function of skin. They learn about the different types of skin cancer and the SPF rating...

A video lesson describes how light absorbs, reflects, and scatters on different surfaces. Pupils learn the result of these different reactions and how humans perceive them.

How does a neon light work and does it actually contain the gas neon? An enlightening simulation encourages pupils to play with circuits and neon lights. They control the capacitance, resistance, and color of the bulb, and the simulation...
