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

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

In this animated object, learners read the dimensions of the different types of vehicles typically considered in highway design.

In this interactive object, learners experience how the three primary flight controls allow a pilot to determine the motion of the airplane during flight.

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.

Explore the different types of fires and the extinguishers used for each type.

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

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

Students review the best practices for using a ruler and answer five basic questions.

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

This project gives a drawing with steps to complete the activity.

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

Students read how to determine and calculate the void ratio for a given sample of soil or aggregate based on the weight-volume relationship.

Students follow step-by-step directions for entering data into a spreadsheet and reporting the results.

Students read how to determine and calculate the saturated unit weight for a given sample of soil or aggregate, based on the weight-volume relationship. Practice problems complete the activity.

Learners study the properties of a right circular cylinder and use geometric formulas to find volume and surface area.

Students read about the different kinds of civil/constitutional rights interest groups and answer multiple-choice questions.

Students read how to determine and calculate the porosity for a given sample of soil or aggregate, based on the weight-volume relationship.

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