In this animated object, learners examine three data compare instructions used by programmable logic controllers (PLCs). A practical application to show how these instructions are used in an industrial setting is provided.

In this animated object, learners compare the mode of action of steroids with the action of amino acid-based hormones.

In this colorful, interactive object, learners examine how materials on the nanoscale compare with those on the macroscale. The focus is on the difference between macroscale and nanoscale gold in both color and melting point.

In this animated activity, learners compare the van der Waals equation with the Ideal Gas Law.

Learners read the definitions of an assumption and a fact. They then provide their own examples of each and compare those to the examples provided.

Learners examine the do's and don'ts of blogging in a school setting. They compare the features of a student blog with those of a classroom community blog. This learning object is particularly designed for instructors.

Learners compare the experience of driving an auto to the circuit responses of RL (resistance/inductance) circuits and RC (resistance/capacitance) circuits. Acceleration, position, speed, and torque are graphed.

Learners read an explanation of how to connect two 7485 ICs to compare binary numbers by creating an 8-bit comparator. Diagrams and charts are presented.

Students read about the characteristics of the ideal operational amplifier and compare them with the industry standard LM741C.

This activity is cognitive. Learners will actively listen to a story activated by the computer. Then learners will take a quiz on their comprehension. Lastly, learners will compare their chosen answers against the answer key to determine how well they really did "actively" listen. (Credit given to Tom E. Wirkus, University Of Wisconsin-LaCrosse for this activity.)

Compare the behaviors and situations that interfere with effective communication in the workplace with those that enhance listening skills and career performance.

Learners compare animations of analog and digital data signals. A short quiz completes the activity.

Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.

In this animated object, learners observe the voltage on a capacitor at various time constants when it either charges or discharges. Students then answer questions in the categories of Identify, Compare, and Compute.

Learners compare the behaviors and situations that interfere with listening on the job with those that enhance listening skills and job performance.

Learners compare the three scales used in pressure measurements: gage, absolute, and vacuum. A brief quiz completes the activity.

Learners examine four stages of rheumatoid arthritis and compare them to the normal synovial joint.

In this learning activity you'll analyze the costs of rent-to-own buying plans and compare those plans to other consumer strategies.

In this learning activity you'll analyze the impact of various factors in their lives. They are then transformed by a new identity. They analyze the potential impact of this new identity and compare it to their initial lives.

Students read about foods that are high in nutrients compared to the number of calories. They identify if certain foods have high or low nutrient density.
