This module provides an introdcution to the concepts of fats and proteins. The basic chemical structure of fats as triglycerides is reviewed, and an introduction to protein structure, including the peptide bond is given.
This module discusses the hydrologic cycle and its impacts on the planet Earth. Additionally, the module addresses connections between the hydrologic cycle, climate and the impacts humans have had on the cycle.
This lesson describes the history and basic operation of the metric system as well as scientific notation. The simplicity of the metric system stems from the fact that there is only one unit of measurement (or base unit) for each type of quantity measured (length, weight, etc.).
This lesson is an introduction to the history and use of the scientific concept of the mole.
This module provides an overview of the nitrogen cycle and the chemical changes that govern the cycle.
This lesson is an introduction to the structure and function of DNA including the process of DNA replication.
This module introduces D. Mendeleev's theories and the modern Periodic Table. Electron configuration as a function of table placement is discussed.
The distribution of earthquakes and volcanoes around the world confirmed the theory of plate tectonics first proposed by Wegener. These phenomena also help categorize plate boundaries into three different types: convergent, divergent, and transform.
This module offers an introduction to the concepts explored by Alfred Wegener, Harry Hess, and others. It is the first in a series on plate tectonics.
Visionlearning uses a variety of diffferent technology to innovate and make learning fun. This module explains the browser plug-ins and other programs that can be helpful when using Visionlearning.
This module discusses how taxonomic names for the genus and species categories are formed and standardized, and how the rules are bent when it comes to famous beasts, such as well known dinosaurs.
This is the first in a series of modules that introduce species taxonomy. This module introduces Carolus Linnaeus' work.
