In this animated object, learners examine how changes in pH affect the salt bonds in strands of hair.
Building a Strand of Hair
By Eileen Bouchard
Students read about the process of hair growth beginning with the joining together of amino acids.
Shoulder, Arm, and Hand Muscles in Action
In this animated activity, learners view the various hand, arm, and shoulder muscles in action. The students test their knowledge of the location of the muscles in a drag-and-drop exercise.
Students read brief descriptions of atoms, molecules, elements, and compounds, and complete a matching exercise that pictures these particles and molecules as pieces of taffy.
Proper Diapering Procedure
By Joan Klinkner
Learners consider the steps and supplies to use when diapering infants and toddlers. The proper diapering procedure not only meets basic care and sanitation needs but builds relationships and promotes the child’s learning. Brief quizzes complete the learning 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.
Chemical Hair Bonds: An Assessment
Learners read this review of chemical hair bonds after completing learning objects on the peptide, disulfide, salt, and hydrogen bonds. Students may e-mail their quiz answers to their instructor.
The Peptide Bond
In this animated object, learners examine the properties of the peptide bond and how the bond relates to the structure of hair.
The Hydrogen Bond
In this animated object, learners examine the properties of the hydrogen bond and how the bond changes when hair is shampooed or styled.
By Glenn Sokolowski
In this interactive object, learners examine standard and metric thread specifications used in engineering drawings. In a brief quiz, they identify various internal and external thread representations.
