The student sees a list of 30 of the most often misspelled words used in business. In one exercise, the student listens to each word and then keys in the spelling of that word. In the next exercise, the student matches synonyms.
In this interactive game, learners answer 30 questions about early childhood education activities and skills. Up to three people can play on the game board at one time.
The Effect of Temperature on the Vapor Pressure of a Liquid
Learners examine how vapor pressure is calculated. The vapor pressure of a liquid increases with increasing temperature. If the heat of vaporization and the vapor pressure at one temperature are known, the vapor pressure at a second temperature can be calculated.
Learners examine graphs and read that the heat of fusion is the heat energy absorbed by one mole of solid as it is converted to liquid, while the heat of vaporization is the heat energy absorbed by one mole of liquid as it is converted to gas.
Learners observe that the volume of one mole of any gas is 22.4 L at standard temperature and pressure. An illustration shows that only the mass of the molar volume differs with the identity of the gas.
Learners answer questions about medication from a game board with the headings "Pituitary," "Thyroid," and "Adrenal." Up to three people can play at one time. Contestants "buzz in" their answers to accumulate points.
The learner studies how electrons travel from one atom to the next. Examples demonstrate how voltage is created by the use of a battery or through magnetism. A quiz completes the activity.
Calculating Bend Allowance for Press Brake Forming
Introduces two methods of determining bend allowance; one is simple and is an approximate, the other is more precise. Interactive part has learner calculate bend allowance and blank size.
Learners read an explanation of how the Magnetron Ignition System uses a solid state switching component, a step-up transformer, and magnetism to provide a high voltage spark in a one-cylinder combustion engine.
Learners examine a 555 integrated circuit, which functions as a one-shot monostable multivibrator, and then test their knowledge. Immediate feedback is provided. Animations are used to show the sequential operations.
Learners read a description of the wiring configuration of a residential Edison Wire System, which consists of a transformer secondary circuit. The circuit supplies two 115-volt sources and one 230-volt source.
Learners study the method of using more than one track and quadrature modes to improve the resolution of an optical encoder. A brief quiz completes the activity.
