Learners follow steps to establish the lower and upper limits in a spreadsheet.
In this animated object, learners examine the function and location of the motor neurons and the damage that can result when they are injured.
In this well-illustrated object, learners examine basic floral anatomy. The flower is the reproductive organ of the angiosperm.
This project gives a drawing with steps to complete the activity.
Learners examine the use of the tolerances displayed in a title block by calculating the minimum and maximum allowable size of a fabricated part. In a brief quiz, students determine whether a part is usable or should be scrapped.
In this interactive object, learners answer 25 questions regarding part or assembly drawings. The basic areas of blueprint reading are covered.
Students read an explanation of the common-source and source-follower amplifiers. Gain formulas are developed and an example is given.
Understand the op-amp buffer configuration and calculate basic circuit impedance.
In this animated object, learners view molecules as they collide and move between two different solutions. They also observe what happens when the temperature of the solutions is raised or lowered.
In this interactive and animated object, learners examine why the piston of a hydraulic cylinder extends slower than it retracts. A brief quiz completes the activity.
In this animated object, students observe how ATP energy is used to move substances across the cell membrane from an area of lower concentration to an area of higher concentration and when something too large needs to get in or out of a cell.
In this animated activity, learners examine how an adjustable pressure-reducing valve can produce a pressure that is lower at its output than at its input.
