General Shop Safety - Hazardous Materials Safety (SDS)
In this learning activity you'll review the hazardous materials safety document which display an example of a SDS or MSDS (Material Safety Data Sheet).
In this animated activity, learners examine the circuitry in a DC variable speed drive that keeps the motor running at a constant speed as the load varies.
In this animated activity, learners examine the circuitry in a DC variable speed drive that causes the motor to accelerate or decelerate at slow rates. This learning object has audio content.
In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.
In this learning activity, you'll watch an animated explanation of the terms class and object as used by computer programmers, and then contrast the differences.
In this learning activity you'll review how every protein molecule of an organism is synthesized by that organism in a prescribed process. This activity helps students understand the fundamental life process of making protein.
In this well-illustrated activity, learners examine the three types of intermolecular forces: dipole-dipole forces, London or Van der Waals forces, and the hydrogen bond. Two interactive questions are included.
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.
