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.

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

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

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

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

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.

In this learning activity you'll review the operation of a NOR gate by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

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 describe the operation of a logic inverter using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

In this learning activity you'll explore the operation of a NAND gate using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

In this interactive object, part 3 in a series, learners follow the steps of the “mathemagician” to examine four numerical curiosities: What’s Special About 1089, Perfect Squares: 1089 and 9801, The Mathematical Significance of 1776, and The Calculator Number Game. The learner will also study six number patterns and look at one remarkable table. Immediate feedback is provided.

In this learning activity, you'll be introduced to Third Normal Form and you'll design a table following these rules.

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.

In this animated object, learners examine the chemistry behind table salt.

In this learning activity you'll discover how the visual perception concept influences your understanding of unstable figures.

This video will demonstrate using adjustable parallels to measure a part.

Learners watch a video and an animated depiction of the operation of the feed section of a corrugated press. They also read descriptions of the feed table, side guides, feed wheels, feed gates, and the feed roll.

Learners study animations to see the connection between temperature and resistance as they examine the operation of an RTD. A table is used to convert resistance readings to the corresponding temperatures. A brief quiz completes the activity.

Learners examine a table of common polyatomic ions. Eight examples are provided for practice.

In this learning activity you'll identify acceptable paraphrases of source material.
