In this interactive object, learners calculate the amount of heat evolved or absorbed in chemical reactions. Four practice problems are provided.
The Formation of Ester Bonds in the Synthesis of Lipids
By Richard Wilkosz
In this animated object, learners examine the formation of ester bonds in the synthesis of lipids using triglyceride biosynthesis as an example. Ester bond formation is described as a dehydration synthesis reaction.
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
In this well-illustrated activity, learners examine the three types of intermolecular forces: dipole-dipole forces, London or Van der Waals forces, and the hydrogen bond. Two interactive questions are included.
Common Types of Oxidation-Reduction Reactions
Learners identify combination, decomposition, displacement, and combustion types of redox reactions. They also watch a video clip that demonstrates the reaction of sodium and water.
By Kaye Krueger
The learner reads an explanation of all of the elements that comprise a future-state map. A map is shown.
Logic State Signals
By Terry Bartelt
In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.
Logic State Indicators
Instructions on how to interpret state indicator symbols for input and output terminals of digital devices is presented.
Students observe the operation of a tri-state buffer used in digital electronics. A brief quiz completes the activity.
Thank you for this wonderful lesson. Textbooks dont do justice to mathematical processes such as this, because they are not static processes. Please make more of these.
