This animated lesson shows several ways that a hydraulic pressure switch, connected in a ladder circuit, causes the cylinder of a hydraulic circuit to perform various applications.

Learners examine how to convert numbers from rectangular to polar form and from polar to rectangular form using a TI-83 Plus calculator.

Learners study the process of mathematically converting temperatures between the Fahrenheit and Celsius scales.

In this animated activity, learners examine how the speed of a motor may change if the voltage from the power source fluctuates due to power line irregularities. This lesson has audio content.

In this animated object, learners examine the properties of the peptide bond and how the bond relates to the structure of hair.

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.

Students answer five questions concerning magnetism.

In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.
