The Neuromuscular Junction
By Barbara Liang
In this animated object, learners examine the major events that occur at the neuromuscular junction.
Lifecycles of Animals and Plants
In this animated activity, sexual reproduction in animals is contrasted with the alternation of generation lifecycle of plants.
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine phase diagrams that show the phases of solid, liquid, and gas as well as the triple point and critical point.
The Juxtaglomerular Apparatus
By Becky Polk-Pohlman
In this animated and interactive object, learners examine the location, structure, and function of the juxtaglomerular (JG) apparatus.
By Bruce Forciea
In this animated object, learners view the "T" and "P" waves and the "QRS complex." A brief quiz completes the activity.
Statics - Trig: Law of Cosines
By Steve Whitmoyer
In this interactive object, learners use the Law of Cosines to calculate forces.
By Jill Larson
In this interactive lesson, students examine the quantitative relationship between chemicals in a balanced mathematical equation.
Ideal Gas Law
By Dr. Miriam Douglass, Dr. Martin McClinton
In this interactive object, learners use the ideal gas law to solve a practice problem.
Spelling of Fungi Names
By Marise Hussey
Learners listen to the pronunciation of fungi names and then type the terms. They may choose the number of names that they wish to spell (up to 13). Immediate feedback is given, and a final score is provided at the end of the activity.
Slope and Intercept on Graphing Calculators
By Ron Keys
The learner reads directions for finding the slope, intercept, and correlation coefficient for a group of ordered pairs using one of eight different scientific calculators.
Newton's Third Law of Motion - Video
By Kim Ristow
In this learning activity you'll examine Newton's Third Law: for every action, there is an equal but opposite reaction.
The Cell: Passive Transport Diffusion (Video)
Explore what passive transport diffusion is and how it moves water through a membrane.
The Unipolar and Multipolar Neurons
Learners examine the location, structure, and function of the unipolar and multipolar neurons.
The Four Types of Chemical Reactions
In this animated object, learners examine synthesis, decomposition, exchange, and reversible reactions.
The Sense of Smell
In this animated object, learners trace the olfactory pathway from the nasal cavity to the olfactory cortex.
In this learning activity you'll review the structure and function of the different tissues of the human body.
The Sense of Taste
In this interactive object, learners examine the structure and function of the sense of taste.
Respiratory System Gas Exchange
In this animated object, learners examine the mechanisms for gas exchange among the lungs, blood, and tissues.
The Formation of Ester Bonds in the Synthesis of Lipids
By Richard Wilkosz
In this animated object, learners examine the formation of ester bonds in the synthesis of lipids using triglyceride biosynthesis as an example. Ester bond formation is described as a dehydration synthesis reaction.
The Basidiomycetes of the Fungi Kingdom
Learners examine the lifecycle of basidiomycetes. Terminology and fungi examples are provided.
How Pressure Changes Boiling Temperature
By Terry Bartelt, Terry Fleischman
Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.
The Two-Neuron Knee-Jerk Reflex Arc
In this interactive object, learners examine the neuron pathway into and out of the spinal cord. They complete the activity by testing their knowledge of vocabulary and the location of spinal cord structures.
Learners read a general description of the function and structure of leaves and examine drawings and microscopic views. A matching exercise completes the learning object.
Double Replacement Reactions
In this interactive object, learners identify charges on ions, write new formulas based on charge, and balance equations using coefficients.
Measuring Volume Using a Graduated Cylinder
By Jill Crowder
Learners view an explanation of how to read a graduated cylinder by measuring the lowest portion of the meniscus. A quiz completes the activity.
