The goal of this activity is to develop and use a model to describe that matter is made of particles on a scale that is too small to be seen. You will be making observations of changes supported by a particle model of matter.

Join a group of middle-school students on a visit to a laboratory at the Massachusetts Institute of Technology, where they experiment with "mystery mud" and learn about the relationships between magnetism, particle motion, and changes in...

The class will go back over the Power Point presentation on chemical and physical properties. The teacher will then conduct numerous liquid nitrogen demos. This lesson is used early in the Chemistry course. The learners love it. This...

Students are given a scenario for this lesson where they must use investigative skills like a detective would to decide whether changes that happen to objects in the story are physical or chemical. They then conduct an experiment with...

What's the Matter? is a guided inquiry lesson on classification of matter, physical and chemical properties, and physical and chemical changes. There are two parts to this lesson: (a) concentration game for definitions and (b)...

Learn about the phases of matter in this section of a college textbook. Section defines the phases of matter and discusses how to interpret a phase diagram. Also explored is partial pressures and Dalton's Law. Section also includes...

The chemical change of matter is illustrated in this lab experiment when spaghetti is placed in a solution of baking soda and vinegar. Watch the spaghetti rise to the surface and sink again once the gas is released.

This site helps students construct a model of the arrangement of water molecules when present as solid, liquid or gas. Includes background information, lesson plans, links to standards and assessment ideas.
