The Mathematics of Buying: Putting It All Together
Learners tackle this interactive learning object after studying the mathematics of buying. This activity ties together the ideas of net cost, list price, trade discounts, cash discounts, net cost equivalent, and single discount equivalent, as well as the concepts of part, base, and rate.
Learners read about how universities, government agencies, energy companies, and nanotech firms are working together to use nanotechnology to help produce clean water for consumption.
Learners identify various therapeutic interaction strategies to be used when working with children and adolescents to enhance self-esteem, self-concept, self-worth, body image, and coping and communication skills.
This screencast shows how blood droplets are held together by a strong cohesive molecular force that produces surface tension in each drop and on the external force. Surface tension pulls the surface molecules of a liquid toward its interior, decreasing the surface area and causing the liquid to resist penetration.
Learners use the coefficients in a balanced equation to develop the mole ratios of reactants and products involved in the reaction. Five interactive examples illustrate the method, and students test their knowledge by working four problems.
The Operation of a Multiplexer/Demultiplexer Circuit
In this animated object, learners examine how a multiplexer and a demultiplexer work together when their data select lines are connected to the same binary counter.
Students read about Benelux, the three countries in Europe that work together as an economic unit. Students test their knowledge by identifying the countries on a map.
Complex Power: The Sum of the Individual Real and Reactive Powers
The learner views a method to find the total complex power of a circuit in which the individual real and reactive powers are found and then added together. Several examples are shown, along with the power triangles.
The Multiplexer/Demultiplexer IC Data Transfer Circuit
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.
Explore what time management is, how to use a time matrix, and how to put it all together and use our new time management skills to accomplish more during your days.
Op Amp Fundamentals: The Transresistance Amplifier
The current-to-voltage conversion of the transresistance amplifier is examined. The formulas for output voltage and impedance are defined and an example ties the concepts together.
