Students practice identifying common elements from the periodic table by name or symbol.

Learners read definitions of atomic symbols, atomic numbers, and mass numbers and then answer questions about the number of neutrons, protons, and electrons in select elements.

In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.

This interactive object is designed to help learners memorize the schematic symbols used in ladder logic diagrams. Learners quiz themselves using electronic flashcards.

Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.

This interactive object is designed to help learners memorize schematic symbols used in hydraulic diagrams. Learners quiz themselves using electronic flashcards.

This interactive object is designed to help learners memorize schematic symbols used in pneumatic diagrams. Learners quiz themselves using electronic flashcards.

In this interactive object, learners view a mind map of the symbolic interaction Approaches and answer questions about communication and symbols.

Learners study the types of symbols used on a P&ID diagram to indicate instruments. A quiz completes the activity.

In this learning activity you'll review various types of common components used in electronics and view their schematic diagram symbols.

Learners read about the similarities of electronic and hydraulic components and then match the schematic symbols in a drag-and-drop exercise.

In this interactive object, learners view the icons and symbols used most frequently in value steam mapping. A matching activity completes the object.

Learners examine the symbols and values that control surface roughness, waviness, and lay. A brief quiz completes the object.

In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.

The schematic symbols of logic gates used in digital circuits are shown.

In this learning activity you'll read introduction to electrical quantities, units, and symbols and test their knowledge in a matching exercise.

In this learning activity you'll review different math symbols and identify them in a matching exercise.

In this screencast, students read about the basic organization and structure of the periodic table of elements. Students identify elements as belonging to a group, a period, or neither.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

Students read about the six common terms used to represent the powers of ten in the field of electronics and complete two matching exercises.
