This web page contains three interactive tutorials for secondary learners on the common chemicals and molecular compounds found in everyday life. The first tutorial, House and Garden is appropriate for Grades 4-6. The second, Do You Know Your Molecules, is an interactive problem set for Grades 6-9. The last tutorial, Symmetry and Point Groups, is targeted to high school chemistry and preparatory chemistry courses.
Reciprocal Net is a database of information about molecular structures. The project involves research scientists from a number of universities who collaborate to provide educators, students, and the general public with learning tools related to crystallography, chemistry, and biochemistry.

4. The Physical Setting
4D. The Structure of Matter
3-5: 4D/E4a. When a new material is made by combining two or more materials, it has properties that are different from the original materials.
3-5: 4D/E6. All materials have certain physical properties, such as strength, hardness, flexibility, durability, resistance to water and fire, and ease of conducting heat.
6-8: 4D/M1a. All matter is made up of atoms, which are far too small to see directly through a microscope.
6-8: 4D/M1cd. Atoms may link together in well-defined molecules, or may be packed together in crystal patterns. Different arrangements of atoms into groups compose all substances and determine the characteristic properties of substances.
6-8: 4D/M5. Chemical elements are those substances that do not break down during normal laboratory reactions involving such treatments as heating, exposure to electric current, or reaction with acids. All substances from living and nonliving things can be broken down to a set of about 100 elements, but since most elements tend to combine with others, few elements are found in their pure form.
6-8: 4D/M6c. Carbon and hydrogen are common elements of living matter.
6-8: 4D/M10. A substance has characteristic properties such as density, a boiling point, and solubility, all of which are independent of the amount of the substance and can be used to identify it.
6-8: 4D/M11. Substances react chemically in characteristic ways with other substances to form new substances with different characteristic properties.
9-12: 4D/H7b. An enormous variety of biological, chemical, and physical phenomena can be explained by changes in the arrangement and motion of atoms and molecules.
9-12: 4D/H8. The configuration of atoms in a molecule determines the molecule's properties. Shapes are particularly important in how large molecules interact with others.
