Robotic welding is an increasingly popular tool used in industrial welding applications. Knowing how to program the robot is key. Explore how to improve your programming skills by using calls and unconditional jumps in this learning activity.

Learners read an introduction to arterial blood gasses and then identify uncompensated ABGs.

In this scenario, learners measure a roof to determine the number of shingles needed to cover it.

In this interactive object, learners examine standard and metric thread specifications used in engineering drawings. In a brief quiz, they identify various internal and external thread representations.

Students read how the transfer function is developed for an RC low-pass filter. A straight line Bode plot is drawn through close approximations.

Students read about cash flow problems and review suggestions for dealing with them.

This primer introduces the student to the correct method of using complex reciprocals in a TI-86 calculator. The solution of total impedance of a parallel circuit in rectangular form is shown.

This primer introduces the student to the proper use of the "EE" function to perform calculations on very large or very small numbers.

Students read about the common characteristics of the Junction Field Effect Transistor. They also explore the schematic symbols and the basic operation of the JFET.

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.

This primer introduces the student to the correct method of using the arctangent function on a TI-86 calculator.

Students view a world map and click on a country or continent to read about how the people there view time. A brief quiz concludes the activity.

Learners read a description of the knob controls, pushbuttons and output terminals on the Wavetek Model 25 signal generator.
