Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

High schoolers are introduced to the mole concept using a discovery-based method. Lesson includes activities with candy that allow students to discover the rules for mole-item, item-mole, mole-mass, and mass-mole conversions.

Ninth graders explore the molecular structure of matter and how it can affect the physical characteristics of a specific material. They demonstrate that isotopes of an element have different masses. Students demonstrate that the rates of...

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...
