Learners examine the periodic table to identify metallic elements that have either fixed or variable oxidation states.
Peptide Bond Formation
By Richard Wilkosz
In this animated object, learners examine the formation of peptide bonds through dehydration synthesis.
Naming Binary Ionic Compounds Containing Variable Oxidation State Cations (Screencast)
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Roman numerals are used to identify the charges on metal cations having multiple oxidation states. Five examples are provided for practice.
Boiling Point of a Liquid
Learners examine how the boiling point increases with increasing pressure. An example from industry is given.
Gas Volume and Molar Amount
By Dr. Miriam Douglass
In this brief object, learners examine the direct relationship between the volume of a gas sample and the number of moles of gas. A problem is presented so students can test their knowledge of Avogadro's Law.
By Terry Bartelt
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.
In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. They then answer six multiple-choice questions.
Logic State Signals
In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.
Logic State Indicators
Instructions on how to interpret state indicator symbols for input and output terminals of digital devices is presented.
Students observe the operation of a tri-state buffer used in digital electronics. A brief quiz completes the activity.
