Learners examine the periodic table to identify metallic elements that have either fixed or variable oxidation states.
Absolute Zero Temperature
By Dr. Miriam Douglass, Dr. Martin McClinton
Learners view illustrations showing the direct dependence of the volume of a gas on temperature and consider the relationship between the Kelvin and Celsius temperature scales.
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.
Identifying Compounds and Ions
By Jill Larson
Learners complete an exercise to match chemical formulas with the names of binary compounds, tertiary compounds, and ions.
The Kinetic Theory of Gases
In this animated activity, learners examine what gases are composed of and how their particles interact. They also consider several assumptions that form the basis for the Kinetic Theory of Gases.
Attributes of a Class: Fields and Properties
By Ryan Appel
In this learning activity you'll discover how C#, attributes provide a way of associating data with an object in two forms - Fields and Properties.
Programming in C++ Using Constants
In this learning activity you'll discover the const keyword and it’s uses in C++.
Variables in Computer Programming (C#)
In this learning activity you'll define what a variable is, how they're used in the C# programming language, and how the computer works with variables under the hood.
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.
