Solubility of Ionic Compounds in Water
By Dr. Miriam Douglass, Dr. Martin McClinton
Learners view movie clips to determine the solubility of two ionic compounds. They also examine a solubility chart and predict the solubility of compounds.
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.
In this interactive object, students examine how the volume and temperature of an ideal gas relate under conditions of constant pressure and quantity.
