In this animated and interactive lesson, learners examine additive and subtractive color theories.

In this screencast, learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.

In this animated and interactive object, learners use a color code to understand the operations of a hydraulic circuit. A brief quiz completes the activity.

In this interactive object, students complete progressively more difficult exercises as a way to improve their ability to recognize resistor color code values.

In this animated object, students examine the shades that result from mixing primary and secondary colors. Color tone and level are also defined.

This interactive learning object is designed to help learners memorize the color code used on some hydraulic schematic diagrams. Learners quiz themselves using electronic flashcards.

In this learning activity you'll build a resistor's color code based on the bands.

In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.

Students examine how to interpret resistor color code bands to determine resistance values and tolerance ranges. This interactive learning object has audio content and includes exercises.

In this animated object, learners pop balloons to see the medical term for a color or condition.

In this colorful, interactive object, learners examine how materials on the nanoscale compare with those on the macroscale. The focus is on the difference between macroscale and nanoscale gold in both color and melting point.

Learners read how they can make menus more pleasing to the senses by paying attention to shape, form, texture, temperature, color, flavor, and visual appeal.

In this animated and interactive object, learners examine the inverse proportionality of wavelength and frequency and their relationship to the speed of light.

In this learning object you'll review color photographs of a Brown & Sharpe Universal Cylindrical Grinder.

In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.

Learners view colorful animations showing the operation of a VR stepper motor.

In this colorful and interactive object, learners examine the structure and function of muscle and connective tissues. A quiz completes the activity.

In this colorful activity, learners follow the path of a bill as it begins in the House of Representatives.

Students view an enlarged, colorful depiction of the contents of an average square inch of skin.
