In this learning activity you'll practice using the 4-input truth table.

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

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 screencast, we review the positions of metals, metalloids, and nonmetals in the Periodic Table and the general characteristics of each.

Instructions on how to use and construct a truth table for digital devices are provided.

Explore what referential integrity is, why it's important to reliable data organization, and learn how it enforces constraints.
