Naming Compounds Containing Polyatomic Ions
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine a table of common polyatomic ions. Eight examples are provided for practice.
Naming Binary Ionic Compounds Containing Variable Oxidation State Cations (Screencast)
Roman numerals are used to identify the charges on metal cations having multiple oxidation states. Five examples are provided for practice.
Naming Binary Ionic Compounds Containing Fixed Oxidation State Cations
Learners examine a table containing the names of common cations and anions.
Muscle Cell Contraction
By Barbara Liang
In this animated activity, learners examine muscle cell contraction and relaxation and consider the role of calcium ions.
Muscle and Connective Tissue
In this colorful and interactive object, learners examine the structure and function of muscle and connective tissues. A quiz completes the activity.
Movement Terminology
In this animated object, the learner examines 17 types of joint movement.
Moles
By Jill Larson
In this animated object, students are introduced to moles as a measurement.
Mole Ratios in Chemical Equations
Learners use the coefficients in a balanced equation to develop the mole ratios of reactants and products involved in the reaction. Five interactive examples illustrate the method, and students test their knowledge by working four problems.
Molarity
Students solve a molarity problem in a drag and drop exercise.
Microbial Flora in Body Sites
By Dawn Madl
In an interactive exercise, learners identify the human body sites that harbor a normal resident flora and the sites that are sterile.
Methods of Producing Electricity
By Terry Bartelt
In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
Metabolic Pathways
By Elizabeth Yoon
In this screencast, learners categorize different metabolic activities as catabolic or anabolic and follow a glucose molecule through the processes of glycolysis, aerobic respiration, and fermentation.
Melting Point and Freezing Point
Learners observe that the melting of a solid and the freezing of its liquid occur at the same temperature. The melting point is an intrinsic property and is used to identify a substance.
Medical Terminology Jukebox
By Karla Hartzheim
Learners read and listen to the pronunciation of hundreds of medical terms that are arranged in a "jukebox." The terms are listed alphabetically and according to the following categories: aerobic and anaerobic microorganisms, blood bank, coagulation, fungi microorganisms, hematology, protozoa, and urinalysis. This learning activity requires a computer that is equipped with speakers.
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.
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.
Mass Versus Weight
By Kim Ristow
In this learning activity you'll explore the difference between mass and weight.
Macroscale vs. Nanoscale
By Karen Nordell
In this colorful, interactive object, learners examine how materials on the nanoscale compare with those on the macroscale. The focus is on the difference between macroscale and nanoscale gold in both color and melting point.
Lifecycles of Animals and Plants
In this animated activity, sexual reproduction in animals is contrasted with the alternation of generation lifecycle of plants.
Lewis Dot Structures of Covalent Compounds
In this interactive and animated object, students distribute the valence electrons in simple covalent molecules with one central atom. Six rules are followed to show the bonding and nonbonding electrons in Lewis dot structures. The process is well illustrated with eight worked examples and two interactive practice problems.
Leaves
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.
Learning the Elements of the Periodic Table by Name or Symbol
By Mona Wenrich
Students practice identifying common elements from the periodic table by name or symbol.
Isotopes
The definition of an isotope is illustrated using the three isotopes of carbon. The three isotopes of hydrogen are discussed as exceptions.
Ions
Ions are electrically charged particles obtained from an atom or from a chemically bonded group of atoms by adding or removing electrons. Eight examples illustrate the number of protons, neutrons, and electrons in positive ions (cations) and in negative ions (anions).
Ion Charges
In this interactive object, the learner practices identifying charges on ions.
