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.
Product Yields in Chemical Reactions
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine the meaning of theoretical yield, actual yield, and percent yield. They test their knowledge by solving two problems.
Reading a Triple Beam Balance
By Jill Crowder
Students identify the parts of a triple beam balance and practice measuring the mass of objects.
Introduction to the Periodic Table
By Mona Wenrich
Students read about the basic organization and structure of the periodic table of elements. By clicking on the symbol, they can read that element's atomic number and weight. In an exercise, students identify elements as belonging to a group, a period, or neither.
Shapes of Simple Molecules - Part 1
By Dr. Miriam Douglass, Dr. Martin McClinton
In this animated and interactive object, learners observe how two, three, or four groups of electrons around the central atom cause the shape of the molecule to be linear, trigonal planar, bent, tetrahedral, or pyramidal. Seven examples and eight interactive questions are provided.
The Twelve Principles of Lean Manufacturing
By Weldon Faull
Following a "cut the fat" theme, learners click on 12 drawings of pigs to read about the principles of lean manufacturing.
Matchless Manufacturing Company: An Exercise in Lean Thinking
By Dan Ost
In this interactive lesson, students use critical thinking to determine the best lean manufacturing initiative when solving problems for the fictitious Batchless Manufacturing Company.
Setup Reduction/Quick Changeover
By Kaye Krueger
Learners view steps to reduce changeover time in a manufacturing operation.
The Impact of Batch Size Reduction
In this animated object, learners examine what happens to lead and cycle times when the batch size is reduced.
Oxidation States of Ions
Learners examine the periodic table to identify metallic elements that have either fixed or variable oxidation states.
