Learners examine the periodic table to identify metallic elements that have either fixed or variable oxidation states.
Gas Volume vs. Temperature (Charles's Law)
By Dr. Miriam Douglass, Dr. Martin McClinton
In this animated object, learners examine how gas volume varies directly with absolute temperature (K at constant pressure). An example of a sample of gas at two conditions of volume and temperature is used to illustrate the law.
Types of Elements in the Periodic Table and Their Properties (Screencast)
By Debbie McClinton, Dr. Martin McClinton
In this screencast, we review the positions of metals, metalloids, and nonmetals in the Periodic Table and the general characteristics of each.
By Terry Bartelt
Learners view an animated presentation showing how the pH level of a cleaning solution is controlled in a closed-loop system in a manufacturing setting. A quiz completes the activity.
The Three States of Matter
In this animated and interactive object, learners examine the properties of liquids, solids, and gases.
In this animated and interactive object, learners examine how a variable voltage is obtained from a variable resistor that is wired as a potentiometer across a fixed DC power supply.
Common Types of Oxidation-Reduction Reactions
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners identify combination, decomposition, displacement, and combustion types of redox reactions. They also watch a video clip that demonstrates the reaction of sodium and water.
The Variable Reluctance Stepper Motor
Learners view colorful animations showing the operation of a VR stepper motor.
By Kaye Krueger
The learner reads an explanation of all of the elements that comprise a future-state map. A map is shown.
Quality Basics: The Scatter Plot
By Mary Lee Rudnick-Kaun
In this learning activity you'll review independent and dependent variables and view a demonstration of the positive and negative correlation.
