The Food Pyramid
By Michele Williams
In this learning activity you'll explore the food pyramid and the recommended services.
The Cell Cycle
In this animated object, learners examine the different phases of a cell's life.
The Cell: Passive Transport Osmosis (Video)
Explore what passive transport osmosis is and how it moves water through a semipermeable membrane.
Passive Transport: Filtration and Facilitated Diffusion
In this animated object, learners examine processes that do not use ATP directly including hydrostatic pressure and facilitated diffusion with carrier proteins.
The Basidiomycetes of the Fungi Kingdom
Learners examine the lifecycle of basidiomycetes. Terminology and fungi examples are provided.
In this well-illustrated object, learners examine basic floral anatomy. The flower is the reproductive organ of the angiosperm.
The Vertebral Column
Learners read a brief description of the vertebral column and examine the distinctive features of the cervical, thoracic, and lumbar vertebrae.
The Autonomic Nervous System - Sympathetic Division
Learners examine the function and wiring of the sympathetic nervous system.
Measuring Gas Pressure
By Dr. Miriam Douglass, Dr. Martin McClinton
Learners convert units used to designate pressure. Units for pressure are atm, mm Hg, torr, and pascal.
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine the meaning of oxidation, reduction, and half-reaction, and watch a film showing the deposition of copper metal from the reduction of copper (II) ion by aluminum. A brief quiz completes the activity.
Atomic Structure and Ionic Bonding
In this animated object, learners examine the chemistry behind table salt.
Atomic Symbols, Atomic Numbers, and Mass Numbers
Learners read definitions of atomic symbols, atomic numbers, and mass numbers and then answer questions about the number of neutrons, protons, and electrons in select elements.
Red Blood Cells
In this animated and interactive object, learners examine the red blood cell's life cycle and function. A brief exercise completes the activity.
Biomolecules: The Proteins (Video)
By Becky Polk-Pohlman
Explore what proteins are, their structure, and their functions.
Introduction to Safety in the Chemistry Lab (Video)
By Bruce Bell
Learners read about lab equipment and basic safety measures. In a quiz, they view photos and determine if the lab technicians pictured are using safe practices.
Summary of Energy Yield During Cellular Respiration
Learners review a graphic summary of the three series of reactions that occur during cellular respiration and the net energy (ATP) yield of that process.
Vapor pressure is the pressure exerted by molecules in the gas phase in equilibrium with a liquid or a solid. Two examples are used to illustrate vapor pressure: the drying of clothes and the evaporation of ice.
The Brain - Anatomy and Function (Screencast)
By Susan Heitman
In this screencast, learners review and reinforce their knowledge of brain anatomy and function.
Chytrids, as members of this group are known, are found everywhere. In this animated learning object, students examine the role of chytrids and their impact on the environment.
Physiological Events at the Neural Synapse
In this learning activity you'll review information on the neural synapse.
Calculation of Atomic Weight from Isotopic Composition
Learners examine the method for calculating the atomic weight of copper from the natural percent composition of each of its two isotopes.
Construction of the Cell Membrane (Video)
In this video you'll study the structure of the cell membrane and construct it using the correct molecules.
Changes in Our World: Chemical and Physical (Screencast)
By Deb Simonson
In this screencast, learners examine the kinds of physical and chemical changes that occur in substances.
