Students read an explanation of chemical formulas in this animated activity. A quiz completes the object.
Oxidation States of Ions
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine the periodic table to identify metallic elements that have either fixed or variable oxidation states.
Biomolecules The Carbohydrates
By Barbara Liang
Learners read a brief introduction to monosaccharides, disaccharides, and polysaccharides. The processes for dehydration synthesis and hydrolysis are shown.
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.
Calculating Gas Density from Standard Molar Volume
Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.
The Peptide Bond
By Eileen Bouchard
In this animated object, learners examine the properties of the peptide bond and how the bond relates to the structure of hair.
Methods of Producing Electricity
By Terry Bartelt
In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
Changes in Our World: Chemical and Physical
By Laurie Jarvis, Deb Simonson
In this animated object, learners examine the kinds of physical and chemical changes that occur in substances. They practice identifying examples of each.
The Disulfide Bond
In this animated lesson, learners read about the disulfide bond, the second strongest chemical bond in the hair. This bond can only be altered by chemicals.
Endothermic vs. Exothermic Reactions
In this animated object, learners examine how the heating or cooling steps in a manufacturing process work to control a chemical reaction.
