The learner will use the deceptively simple sine bar to measure angles to minutes or even half minutes.

Introduces two methods of determining bend allowance; one is simple and is an approximate, the other is more precise. Interactive part has learner calculate bend allowance and blank size.

In this learning activity you'll understand what flow charts are and how they're used to create computer programs.

The learner will understand the inner workings of the strain wave gear principle.

Learners will follow general tips and tricks for improving their basic welding technique.

In this animated and interactive object, learners follow steps that begin with choosing the correct drive roll and include feeding the electrode wire from the spool to the welding gun.

In this learning activity you'll recognize potential safety hazards around grinding equipment

This lesson gives the student an overview of grinding wheels and pedestal grinder procedures.

Learners read how to calculate the MOD number and how it is used.

Explore the different types of personal protective equipment, which protects you against workplace hazards

Users read work instructions and view a drawing and calculations for turning on a lathe using a digital readout.

The learner will learn the programming steps that are used to create circular motions with robots.

In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.

In this learning object, you’ll explore what tools should be a part of every welding tool bag.

Learners follow steps for sizing a car wash interceptor according to the Wisconsin Administrative Plumbing Code. A quiz completes the activity. (Hover your mouse in lower right corner to see the next button)

In this animated activity, learners view the input and output leads of a JK flip-flop. They also see how it functions in each mode of operation. A brief quiz completes the learning object.

Learners view wire feed power sources ranging from 110-volt, single phase units to 460-volt, three-phase units. A description and photos of each are provided.

In this learning activity you'll explore units of measurement.

In this learning activity, you’ll explore the characteristics of common, carbon steel shielded metal arc welding electrodes, which fall under American Welding Society specification A5.1.

In this animated activity, students view the operation of a 4-bit serial-in serial-out register. A brief quiz completes the learning object.

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 animated activity, the learner examines how a 74150 IC multiplexer and a 74154 IC demultiplexer work together when their data select lines are connected to the same input devices.

Learners read how the NOR gate can be configured to obtain the other common logic gates. Schematics and Boolean expressions demonstrate how the AND, OR, and Hex Inverter functions are achieved through the use of only NOR gates

In this learning activity, we’ll explore the impact of electric shock on the human body.
