In this animated object, students are introduced to moles as a measurement.
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners assign oxidation numbers to atoms in neutral compounds and in polyatomic ions. Six examples are worked through in detail, and three problems are provided.
Standard Molar Volume
By Dr. Miriam Douglass
Learners observe that the volume of one mole of any gas is 22.4 L at standard temperature and pressure. An illustration shows that only the mass of the molar volume differs with the identity of the gas.
Acids & Bases
By Jill Larson
Students read different definitions of "acids" and "bases." In an interactive exercise, they identify if a substance is an acid or a base.
Learners examine how melting, vaporization, and sublimation require energy input while freezing and condensation release energy.
Overflow and Underflow for Signed Binary Numbers
By John Casey, Terry Bartelt, Terry Fleischman
Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.
Converting Between Gray and Binary Codes
By Terry Bartelt
Learners follow steps to convert numbers from Gray code to binary code. They then view steps to change binary values to Gray code numbers.
Adding Fractions With Unlike Denominators
By Tina Dietzman
Learners follow steps to add fractions with different denominators. They also review fraction concepts, do a drag-and-drop exercise involving fraction terms, and add fractions with common denominators.
Aspergillus in the Property Room
By Vickie Brugger
In this learning activity learners will be hear about aspergillus found on marijuana and the potential health hazards that can affect a property room manager. Learners will hear about preventative measures.
The Reynolds Number
In this animated learning object, users study the factors that affect a pipe’s fluid flow and how those factors pertain to a numerical value (the Reynolds Number).
