It then presents a set of questions by which students review and enhance understanding of what they studied. In a sample tutorial on the Law of definite proportions, students are introduced to the definition of conservation of mass, elements, and compounds. They are encouraged to solve questions about a series of experiments, in which the indicated amounts of sodium and chlorine combine to form common salt, to examine law of definite proportions. In section four, Determining Empirical Formulas, students are provided with oxidation and reduction experiments. With the help of computer simulations, students determine empirical formulas of completely oxidized magnesium formed by the on screen experiment.
Additional features includes a vocabulary review and review problems.
Selecting vocabulary review enables students to test their knowledge of a topic's key terms by matching vocabulary words with their provided definitions. Review questions leads to a presentation of problems included in the tutorial lessons from that section of the disk, as well as additional problems on the topic. Whenever students are stuck on a problem, upon using question mark, they can get the correct answer with background information. Contact vendor for further information.
