Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

Adsorption, not absorption, is when atoms stick to the surface of an object, like water sticking to a grain of sand. An informative lesson delves into adsorption, teaching physical and chemisorption and the factors that affect them....

Due to surface tension, dew — a liquid, is spherical in shape. Learners explore the properties of liquids in activity seven in this series of 36. Beginning with its basic properties such as boiling point and moving through to surface...

Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

Crystal comes from a Greek word meaning ice. Activity eight in a series of 36 has class members analyzing amorphous and crystalline solids and further classifying them based on their forces. They then explore solids, learning about unit...

In this first land plants worksheet, students read about the major events that allowed plants to evolve on Earth. Students read about the primary and secondary atmospheres, the formation of the ozone layer to protect from UV light and...

The General Chemistry Virtual Textbook, or Chem 1, is broken into several sections covering various aspects of topics related to chemistry. This section deals with both Boltzmann Distribution and the velocity of gas molecules.

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.

As part of the General Chemistry Virtual Textbook, this site continues a study conducted on various topics related to gases. As a specific topic, the site covers an introduction to kinetic molecular theory.

A discussion of the variety of forces which hold molecules together. The relative strengths of these forces for the various states of matter is discussed. The effect of such forces on the boiling points and other phase change...

The General Chemistry Virtual Textbook, or Chem 1, is broken into several sections covering various aspects of topics related to chemistry. This section deals with the basic components of the Kinetic-Molecular Theory in addition to...

The General Chemistry Virtual Textbook, or Chem 1, is broken into several sections covering various aspects of topics related to chemistry. This section deals with diffusion along with topics such as concentration gradient and random...

This site has a brief description of the differences in particles in a gas, liquid, and solid. Animated microscopic pictures demonstrate the molecular movement in each state. Information is then summarized in an easy-to-read chart.

Describes the bond angle of the water molecule during the transition from liquid to gas state. Also provides several examples and explanations for responses and answers given.

Use this resource to learn about the three different phases of water; solid, liquid, and gas. What happens to water as it changes into a solid or gas? Includes short and easy to do activity.

Read about the chemical compound ammonia and learn how it is part of the Nitrogen Cycle.

Concept animation compares molecular movement of solids, liquids, and gases.

Article explaining what halocarbons are, where they occur in nature as well as man-made sources, how they are used, and their negative environmental impact. (Published: October 28, 2011)

The General Chemistry Virtual Textbook, or Chem 1, is broken into several sections covering various aspects of topics related to chemistry. This section deals with intermolecular forces and topics including repulsive forces and...
