How Pressure Changes Boiling Temperature
Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.

Humidity Measurements
Learners examine dew point and the two types of humidity values, absolute and relative, along with the types of instruments used to measure them. The activity includes a video clip and a quiz.
Tags +
absolute, dew, humidity, measurements, point, relative
Hydrostatic Pressure (Screencast)
In this animated object, learners read about hydrostatic pressure and observe how it is used to measure the level of a material in a container.
Tags +
hydrostatic, level, measurement, measurements, pressure
Industrial Control Classifications
In this animated object, learners examine automated manufacturing systems classified as motion control, batch process control, and continuous process control.
Tags +

Lewis Dot Structures of Covalent Compounds
In this interactive and animated object, students distribute the valence electrons in simple covalent molecules with one central atom. Six rules are followed to show the bonding and nonbonding electrons in Lewis dot structures. The process is well illustrated with eight worked examples and two interactive practice problems.

Oxidation-Reduction Reactions
Learners examine the meaning of oxidation, reduction, and half-reaction, and watch a film showing the deposition of copper metal from the reduction of copper (II) ion by aluminum. A brief quiz completes the activity.
Tags +
Precipitation Reactions
In this interactive and animated object, learners use solubility rules to predict when an insoluble ionic compound will precipitate in a double replacement reaction. Step-by-step examples are given.
Tags +
Product Yields in Chemical Reactions (Screencast)
Learners examine the meaning of theoretical yield, actual yield, and percent yield. They test their knowledge by solving two problems.
Tags +
