Atomic weights are used to convert the mass of a sample into the number of moles of the element in the sample and vice versa. Four examples are provided for practice.
Introduction to the Periodic Table (Screencast)
By Mona Wenrich
In this screencast, students read about the basic organization and structure of the periodic table of elements. Students identify elements as belonging to a group, a period, or neither.

Learners assign oxidation numbers to atoms in neutral compounds and in polyatomic ions. Six examples are worked through in detail, and three problems are provided.

In this interactive and animated object, learners use solubility rules to predict when an insoluble ionic compound will precipitate in a double replacement reaction. Four step-by-step examples are given.
By Eileen Bouchard
Students read brief descriptions of atoms, molecules, elements, and compounds, and complete a matching exercise that pictures these particles and molecules as pieces of taffy.
Weight- Volume Relationships: Dry Density
By Steve Whitmoyer
Students read how to determine and calculate the dry density for a given sample of soil or aggregate based on the mass-volume relationship.
Weight- Volume Relationships: Saturated Density (Metric)
Students read how to determine and calculate the saturated density for a given sample of soil or aggregate, based on the mass-volume relationship. Practice problems complete the activity.
Reading a Triple Beam Balance
By Jill Crowder
Students identify the parts of a triple beam balance and practice measuring the mass of objects.
Determining Empirical and Molecular Formulas
Learners follow a four-step process to determine the empirical formula of a compound from the masses of its constituent elements. The molecular formula is determined in a fifth step using the molecular weight of the compound.
Newton's Second Law of Motion
By Kim Ristow
In this learning activity you'll examine force, mass, and acceleration to understand this "Law of Acceleration."
