Students examine examples for calculation yield, throughput yield, rolled throughput yield, and payback, each of which is used to analyze process performance in a Six Sigma project.
Nouns: Count and Noncount with "a Few" and "a Little": Part 4
In this interactive lesson, learners study examples of the expressions "a few" and "a little" with count and noncount nouns. They practice using these expressions in a drag-and-drop exercise of 20 sentences.
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.
Vapor pressure is the pressure exerted by molecules in the gas phase in equilibrium with a liquid or a solid. Two examples are used to illustrate vapor pressure: the drying of clothes and the evaporation of ice.
In this interactive lesson, learners study examples of nouns that can be counted and nouns that cannot. They then identify whether a word is a "count" or a "noncount" noun in a practice exercise.
Ions are electrically charged particles obtained from an atom or from a chemically bonded group of atoms by adding or removing electrons. Eight examples illustrate the number of protons, neutrons, and electrons in positive ions (cations) and in negative ions (anions).
