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.
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
In this animated and interactive object, learners examine the inverse proportionality of wavelength and frequency and their relationship to the speed of light.
Measuring Volume Using a Graduated Cylinder
By Jill Crowder
Learners view an explanation of how to read a graduated cylinder by measuring the lowest portion of the meniscus. A quiz completes the activity.
Shapes of Simple Molecules - Part 1 (Screencast)
By Dr. Miriam Douglass, Dr. Martin McClinton
In this animated and interactive object, learners observe how two, three, or four groups of electrons around the central atom cause the shape of the molecule to be linear, trigonal planar, bent, tetrahedral, or pyramidal. Seven examples and eight interactive questions are provided.
The Solid State
In this well-illustrated object, learners examine the structures and properties of the four types of solids: molecular, metallic, ionic, and covalent network. Five interactive questions are provided.
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.
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."
Mass Versus Weight
In this learning activity you'll explore the difference between mass and weight.
