In this learning activity you'll observe how switches are used in local area networks to increase data transmission speeds.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.

Learners observe how a blood drop in flight continually accelerates and increases in velocity over time. As the drop falls, resistance accumulates. The increase in stain diameter relative to distance of a typical 50 ml drop of blood is represented here. This activity has audio content.

In this learning activity you'll explore the effect of connecting voltage sources in series to increase voltage applied to a load.

In this animated and interactive object, learners examine why the voltage produced by an AC drive must be increased when its frequency is increased due to inductive reactance.

The effect of connecting voltage sources in parallel to increase amperage to a load is presented.

In this animated object, learners examine ink trapping, a key technique used by printers to improve the quality of products and to increase efficiency.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency increases from 0 Hz toward resonance.

Learners examine how vapor pressure is calculated. The vapor pressure of a liquid increases with increasing temperature. If the heat of vaporization and the vapor pressure at one temperature are known, the vapor pressure at a second temperature can be calculated.

Learners examine how the boiling point increases with increasing pressure. An example from industry is given.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased from 0 Hz towards resonance.

Learners examine a CBC and study the functions of blood cells, the normal range for each item on the CBC, and possible reasons for increases or decreases from the normal range.

Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.

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.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased above resonance.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency is increased above resonance.

Learners conduct an experiment to illustrate how a greater number of particles in a "vessel" increases osmotic pressure.
