In this animated and interactive object, learners examine the properties of liquids, solids, and gases.

Students read about the basic organization and structure of the periodic table of elements. By clicking on the symbol, they can read that element's atomic number and weight. In an exercise, students identify elements as belonging to a group, a period, or neither.

Learners view illustrations showing the direct dependence of the volume of a gas on temperature and consider the relationship between the Kelvin and Celsius temperature scales.

Atomic weights are used to convert the mass of a sample into the number of moles of the element in the sample and vice versa. Four examples are provided for practice.

In this learning activity you'll describe the operation of an AND gate by using a truth table, a waveform diagram, a Boolean Algebra equation, a switch analogy, and a written definition.

In this learning activity you'll review how an OR gate operates using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

This interactive activity represents the grid modeling technique, a heuristic model for choosing a centralized location for a manufacturing or distribution center within a supply chain network. The formula calculates a central point between the suppliers and the markets. This object requires the latest version of Flash Player.

After a brief review, the student solves five practical shop problems using right angle trigonometry.

In this learning activity you'll practice calculating quadratic equations using the 'completing the square' method.

Test your knowledge of properties of quadrilaterals, area of 2D figures, and surface area and volume of 3D figures.
