Using an engaging combination of student interviews, humor, animations and expert commentary by leading health professionals, this program exposes the most common myths about sexually transmitted infections. While abstinence, including abstaining from oral sex, is the only way to completely avoid STI infections, the program stresses the importance of latex barriers for students who are sexually active. Students are encouraged to get tested if they have engaged in risky sex and students who may have symptoms of an STI are urged to see a clinician right away.

Looks at thermodynamics and converting heat into energy.

An introduction to heat that uses experiments and easy-to-follow text to help readers understand the principles of heat, how it is made, how different kinds of matter conduct heat, and other related topics.

The author explores the emotions and feelings of friends and family members of someone who has been diagnosed with the HIV virus, and discusses medical information and the importance of receiving treatment immediately.

"We often automatically equate heat with temperature to such a degree that we may not take the time to consider what heat really is. Heat refers to the energy that is transferred from one body to another that is at a lower temperature. This transfer occurs often without us knowing it, but it is ever-present and crucial to all life. This volume examines the basics of heat and the related concept of temperature. Detailed diagrams help illustrate such concepts as specific heat capacity and latent heat. Clear text explains the difference between conduction, convection, and radiation, as well as emitters, absorbers, and more" -- Provided by publisher.
