  Physical Science / Beyond the NSES
Atomic Theory I: The Early Days - Modern atomic theory has evolved dramatically from the 19th century view of the atom as a small, solid sphere resembling a billiard ball. This module explores that story: from the discovery of electrons and protons in the late 19th century to the planetary model of the atom in the early 20th century. The module explains the function of subatomic particles as well as their relative size and weight. The concepts of atomic number and atomic mass are introduced.

  Physical Science / Structure of Atoms
Atomic Theory II: Ions, Isotopes and Electron Shells - This lesson explains the presence of ions, isotopes and discusses N. Bohr's theory on the quantum behaviour of electrons. This module is the second in a series on atomic structure.
National Science Education Standard Equivalent:
  Physical Science / Structure of Atoms
Carbohydrates - This module provides an introduction to the concept of carbohydrates as a macronutrient. The biochemical structure of simple sugars and complex carbohydrates are compared and contrasted.
National Science Education Standard Equivalent:
  Life Science / Matter, Energy, and Organization in Living Systems
Chemical Bonding - It introduces the concepts of ionic and covalent bonding. This module is the second in a series on chemical reactions.
National Science Education Standard Equivalent:
  Physical Science / Chemical Reactions
Chemical Equations - It discusses the process of equation writing and balancing chemical equations in perspective of the chemical changes that take place during a reaction. This module is the third in a series on chemical reactions.

Chemical Reactions - Exploring the how and why of chemical reactions, this module describes properties of the inert—or “noble”—gases. It also explains how different elements achieve a stable configuration by bonding to fill their valence shells with electrons, resulting in a chemical compound. The difference between exothermic and endothermic reactions is discussed.

  Physical Science / Chemical Reactions
Fats and Proteins - 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.

Matter: Atoms from Democritus to Dalton - This lesson introduces theories of the structure of matter from the time of the ancient Greeks, to Dalton's eloquent theory of the early 19th century. This module serves as the first in a series on atomic structure.
National Science Education Standard Equivalent:
  Physical Science / Structure and Properties of Matter
Matter: States of Matter - This module introduces Kinetic Molecular Theory and the states of matter and describes the process of phase transitions in matter.
National Science Education Standard Equivalent:
  Physical Science / Interactions of Energy and Matter
Nuclear Chemistry: An Introduction - Beginning with the work of Marie Curie and others, this module traces the development of nuclear chemistry. It describes different types of radiation: alpha, beta, and gamma. The module then applies the principle of half-life to radioactive decay and explains the difference between nuclear fission and nuclear fusion.
