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,...

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...

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.

Students describe how radioactivity relates to alpha and beta particles. Using their properties, they write a descriptive paper about the gamma rays and alpha and beta particles. They calculate q-values and the half-life of a given...
