Learners identify the advantages and disadvantages of four versions of high speed Ethernet. A short quiz completes the activity.

In this screencast, learners read about the parts of the eye.

Learners read how the RL high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

Learners read how the transfer function for a RC high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

Learners examine the Karnaugh map for a three-variable system. Several examples are given.

In this learning activity you'll explore the difference between mass and weight.

In this screencast, learners read about the seven hormones that help regulate blood glucose.

Learners examine the circuitry in a DC variable speed drive that prevents the motor from running at 0 rpm or at maximum speed under certain conditions.

In this learning activity you'll identify the sides of a right triangle with respect to the angles.

Students read about light-emitting diodes, including LED voltage and current, and how to protect against reverse voltage.

Students view the development of the transfer function for a RC high pass filter. They also read how a Bode plot is developed through simple approximation techniques for both the magnitude and phase.

Students take a 13-question quiz to practice reading 25- and 50-division Vernier height gages.

Learners read how the transfer function for a RL high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench, and the resulting Bode plot is compared to the graph from Excel.

Learners read the definition of atomic weight and obtain the weights of elements by viewing the Periodic Table and charts that list atomic weights by name or symbol.

Learners observe current flow throughout the series portion and branches of a parallel circuit. This animated activity includes calculations and a short quiz.

Learners view animations showing how a time-of-flight flowmeter uses ultrasonic sound waves to measure the flow of a liquid.

In this learning activity, you’ll explore four different types of JOINs and understand how they help programmers produce readable reports.

Learners examine the method for calculating the atomic weight of copper from the natural percent composition of each of its two isotopes.

Students read about Afghanistan and view maps. They also answer questions about the country and its neighbors.

Learners will examine the four steps to listen actively to improve relationships.
