Middle School Chemistry: Changes of State
published by the American Chemical Society
written by Patti Galvan and Jim Kessler
This set of multimedia lessons, developed by the American Chemical Society, introduces state change by examining four processes: evaporation, condensation, freezing, and melting. Each process is supported by Flash simulations, related videos, background information for teachers, assessments with answer keys, student reading material, and standards-based lessons. Sample multimedia include Conducting Energy, States of Matter, Water Cycle, Liquid Nitrogen, Specific Heat, and more.

Editor's Note: The authors designed this curriculum to help students understand basic chemistry within a framework of molecular interactions. The molecular models and related animations provide a foundation for understanding states of matter, atomic models and bonding, charge interactions, and chemical change.

Please note that this resource requires Flash.

4. The Physical Setting

4D. The Structure of Matter
  • 6-8: 4D/M3ab. Atoms and molecules are perpetually in motion. Increased temperature means greater average energy of motion, so most substances expand when heated.
  • 6-8: 4D/M3cd. In solids, the atoms or molecules are closely locked in position and can only vibrate. In liquids, they have higher energy, are more loosely connected, and can slide past one another; some molecules may get enough energy to escape into a gas. In gases, the atoms or molecules have still more energy and are free of one another except during occasional collisions.
  • 6-8: 4D/M8. Most substances can exist as a solid, liquid, or gas depending on temperature.
  • 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.
4E. Energy Transformations
  • 6-8: 4E/M4. Energy appears in different forms and can be transformed within a system. Motion energy is associated with the speed of an object. Thermal energy is associated with the temperature of an object. Gravitational energy is associated with the height of an object above a reference point. Elastic energy is associated with the stretching or compressing of an elastic object. Chemical energy is associated with the composition of a substance. Electrical energy is associated with an electric current in a circuit. Light energy is associated with the frequency of electromagnetic waves.

11. Common Themes

11A. Systems
  • 6-8: 11A/M1. A system can include processes as well as things.
11B. Models
  • 6-8: 11B/M1. Models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. They are also used for processes that are too vast, too complex, or too dangerous to study.
  • 6-8: 11B/M4. Simulations are often useful in modeling events and processes.
