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.
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.
The Brain - Anatomy and Function (Screencast)
By Susan Heitman
In this screencast, learners review and reinforce their knowledge of brain anatomy and function.
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.
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)
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.
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.
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.
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.
