Learners examine a table containing the names of common cations and anions.

Students view diagrams of nails and read the client's nail history. They then determine if the affected nail has a disease or a disorder and recommend salon treatment and home care.

In this learning activity you'll explore the process that servers follow to take a name entered on a computer browser and convert it to an IP address.

Components and Operations

Learners examine a table of common polyatomic ions. Eight examples are provided for practice.

In this learning activity you'll explore the operation of a NAND gate using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

This learning object offers a brief summary of the impact of nanotechnology on automobile tires. Learners look at the future of cars, especially the safety and future of automobile tires.

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 listen to a lecture given during the early days of nanotechnology titled, “There’s Plenty of Room at the Bottom.” Dr. Richard Feynman made the presentation to the American Physical Society on December 29, 1959. Animation makes this lecture fun to absorb.

The learner constructs a nail and identifies the terms relating to the structures of the nail in a matching exercise.

Roman numerals are used to identify the charges on metal cations having multiple oxidation states. Five examples are provided for practice.

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.

In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

Users of this learning object review a case study of an online student and her experience with her instructor. They determine the principles of good practice for teaching online.

Students review the rule for pluralizing most nouns. They then complete an exercise.

In this learning activity you'll view a graphical layout of the transactional communication model.

Learners analyze a base-biased npn transistor circuit. A "help" screen is available.

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.

In this learning activity you'll play "How to Really Be a Millionaire" to learn the basics of accumulating wealth.
