Students read an explanation of chemical formulas in this animated activity. A quiz completes the object.
pH and Its Basic Principles
By Joan Kornitz
In this animated object, learners view hydrogen and hydroxide ions in a solution. A brief quiz on the basic principles of the term pH completes the activity.
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.
Ideal Gas Law
By Dr. Miriam Douglass, Dr. Martin McClinton
In this interactive object, learners use the ideal gas law to solve a practice problem.
Science Lab Equipment- Part 1
By Bruce Bell
Students read an introduction to the lab equipment used to contain and dispense chemicals. A quiz completes the activity.
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.
