Reading a Micrometer
By Sue Silverstein
In this learning activity you'll practice reading an inch micrometer.
Transport Processes Requiring ATP
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.
Movement Terminology
In this animated object, the learner examines 17 types of joint movement.
Ohm's Law Practice Problems #1
By Patrick Hoppe
Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
Basic Types of Dimensioning Used in Engineering Drawings
Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.
The Stress Response
In this animated object, learners read a brief description of the roles of the hypothalamus, emotions, and adrenal secretions during the stress response.
Construction of the Cell Membrane (Video)
By Becky Polk-Pohlman
In this video you'll study the structure of the cell membrane and construct it using the correct molecules.
Resistor Color Code Practice
In this learning activity you'll build a resistor's color code based on the bands.
Levels of Prevention
By Lucie Cutler
In this interactive object, learners identify a variety of prevention activities as primary, secondary, or tertiary.
