Students examine standard pressure in this interactive object.
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Vapor pressure is the pressure exerted by molecules in the gas phase in equilibrium with a liquid or a solid. Two examples are used to illustrate vapor pressure: the drying of clothes and the evaporation of ice.
Macroscale vs. Nanoscale
By Karen Nordell
In this colorful, interactive object, learners examine how materials on the nanoscale compare with those on the macroscale. The focus is on the difference between macroscale and nanoscale gold in both color and melting point.
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.
pH and Its Basic Principles
By Joan Kornitz
In this animated object, learners view hydrogen and hydroxide ions in a solution. A brief quiz on the basic principles of the term pH completes the activity.
Using a Lumber Rule
By Patrick Molzahn
Learners read how to use a lumber rule to quickly and accurately estimate board feet. They then use virtual samples to practice the process.
By Terry Bartelt
In this animated object, learners read about hydrostatic pressure and observe how it is used to measure the level of a material in a container.
By James Bourassa
In this interactive object, learners view various components of gears and read descriptions of them. Learners then identify the location of each of these components in a drag-and-drop exercise.
Weight-Volume Relationships: Introduction to a 3-Phase Diagram
By Steve Whitmoyer
In this animated activity, students read about weight-volume relationships within a given sample of soil or aggregate. They complete problems using a 3-phase diagram.
Weight - Volume Relationships: Water (Moisture) Content
This interactive learning object demonstrates how the moisture content is determined for a given sample of soil or aggregate.
