In this animated activity, learners explore three major methods of heat transfer and practice identifying each.

Learners examine graphs and read that the heat of fusion is the heat energy absorbed by one mole of solid as it is converted to liquid, while the heat of vaporization is the heat energy absorbed by one mole of liquid as it is converted to gas.

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 read how the transfer function for a RC low 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 answer questions about the heat treatment of metals using a game show format. Immediate feedback is provided.

The learner will identify the advantages and disadvantages of the four modes of GMAW transfer.

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

In this animated object, learners examine how thermal energy is transferred by conduction, convection, and radiation. A brief quiz completes the activity.

Students learn how to predict how circuits will respond to varying frequency. They solve for the magnitude and phase angles.

In this interactive learning object, the learner practices sizing a tank-type water heater for one- and two-family residences, townhouses, and apartments with individual water heaters.

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 examine 10 steps to consider when passing on farm assets including financial security, partnerships, taxes, lease agreements, gifting, and treatment of heirs.

Students read about the concept of true power and view examples of how it is dissipated as heat is provided.

In this animated and interactive object, learners examine a heat exchanger as an example of an automated closed-loop system.

In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
