In this video, learners view the parts of an animal cell and its organelles.
Absolute Zero Temperature
By Dr. Miriam Douglass, Dr. Martin McClinton
Learners view illustrations showing the direct dependence of the volume of a gas on temperature and consider the relationship between the Kelvin and Celsius temperature scales.
Acid-Base Reactions (Screencast)
Learners view several movie clips that demonstrate the use of an indicator to follow the neutralization reaction that occurs when an acid and a base are mixed. Students test their knowledge in a series of questions. Immediate feedback is given.
Acids & Bases
Students read different definitions of "acids" and "bases." In an interactive exercise, they identify if a substance is an acid or a base.
An Overview of Pulmonary and Systemic Circulation
