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...

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

Hopefully by the time high schoolers are enrolled in your chemistry class, they are skilled with unit conversion. It does not hurt, however, to take an hour early in the school year to review this vital skill. This plan simply provides a...

Young scholars are introduced to the structure of an atom and Dalton's atomic theory through a short video and mini-lecture. They also take a look at the weight of mass and become familiar with the idea of quantum theory

Students 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...
