Here is part one of a two-part instructional activity 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...

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...

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...

Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

There's a container for every matter—liquid, solid, and gas. Pupils design three different containers, each with the capability to hold one of the states of matter, and share their design with the class.     

Explore the properties of gases through one activity and two investigations in which super scientists observe the changes gas makes when encountering different conditions.

Lesson 19 in the series of 36 analyzes the element hydrogen and the s-block elements. Through readings, answering questions, and discussion, learners write about and explain their occurrence, physical and chemical properties, and...

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....

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.

This site provides a discussion of the physical properties of water. Click Home to access the site in Spanish.

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.

An exhaustive set of "lecture notes" on various topics in thermal physics (including thermal expansion). Explanations are well done and more interesting than most. Includes both a mathematical and conceptual treatment of topics. Humor,...

A very descriptive site that allows students to understand the different states of matter at the atomic level. Also discusses the process of phase changes and displays phase change graphs. Thermochemistry is also touched upon for high...

Information about the element, Thorium, atomic number 90. Covers physical properties, atomic properties, how abundant it is on the Earth, where it is found, and details about health-related regulations. Discusses thorium's potential use...

Discusses the chemical and physical composition of coal and why understanding the chemical properties of coal is important for knowing how to process and use it.

A fact card describing the characteristics of calcite and its presence in limestone, its chemical and physical properties, and the composition and structure of a calcite unit cell.

Describes the physical characteristics of Daphnia, their importance as a food source for freshwater fish, their diet, life cycle, and methods of reproduction. Offers tips for how to start and maintain a colony of Daphnia that can be used...

This site takes a look at the Fairy Penguin, the smallest of all the penguins and found in warmer waters along the shores of Southern Australia, Tasmania, and New Zealand. Content includes a focus on this penguin's physical...

Provides photographs and a fact card about the oyster. Discusses where they are found, physical characteristics, the four groups of oysters, how they filter water for food using their gills, predators, reproduction, and the impact of...
