Abstract: Teacher's Guide and Student Workbook are available from DEC's Software Distribution Center.

1. METEST-Practice in the metric system units for measuring length, mass and volume. Consists of a sequence of multiple choice conversion problems that utilize the units most frequently encountered in science courses.
2. DENSITY-This exercise deals with the concept of density. Five different problems are presented, involving the relationships between the fundamental physical qualities of mass, volume and density. Each problem requires some application of the formula: DENSITY = MASS / VOLUME
3. ELECTRONS-Drill in identifying the number of electrons having principal quantum numbers 1,2,3, or 4 in elements with atomic numbers from 1-22.
4. ATOM-Problems giving the atomic number of an element which lies between LITHIUM and TITANIUM on the periodic table. Student required to describe structure of this atom regarding the number protons, neutrons and electrons in various s and p orbitals.
5. PERIODD-Exercise giving the student practice in using the periodic table and applying the Periodic Law. Questions require an understanding of the relationships which exist between elements and their position in the periodic table.
6. COMPOS-Quantitative relationships between the elements that compose simple binary compounds. Compound selected at random from 42 possible combinations of six anions and seven cations. Questions asked concerning percent composition and relative number of grains and moles.
7. EQUATI-Quantitative relationships in chemical reactions, stoichiometry. Students are provided with six balanced equations and must answer a sequence of questions concerning quantitative relationships between substances in three of the reactions.
8. RAOULT-Practice in solving problems which deal with the concentration of a solution and its freezing point, and the determination of molecular weight.
9. MOLAR-Relationship between the moles and grams of a solute and the volume and molarity of the solution.
10. GASLAW-Relationships between temperature, pressure and volume of ideal gases. Practice in applying Boyle's Law, Charlie's Law and the Combined Gas Law.
