In this ideal gas learning exercise, learners read about the conditions necessary for an ideal gas to exist. They also read about the deviations from the ideal gas situation and answer four questions about ideal gases.

Eighth graders examine different solutions.  In this solution material instructional activity students complete a lab activity and several worksheets. 

Eighth graders demonstrate how scientific principles can be used to provide resources in an emergency situation.  In this evaporation lesson students view a demonstration on a solar still and see a brief PowerPoint presentation. 

In this nuclear reaction worksheet, students determine the missing particle from the reaction and then name that particle. This worksheet has 18 problems to solve.

Students explore human growth and development as they participate in class activities, reading and discussion. Worksheet and handouts are included in the lesson.

Fourth graders observe Moon and its features, and record results both in written form and in a drawing on the given template.

Young scholars study about chromatography, a process used to separate mixtures. They see that chromatography is used to detect, separate or purify different substances. This nice lesson plan results in a beautiful t-shirt for each student!

Fourth graders, in groups, examine how particles in warm water move faster than particles in cold water.

Learn about the changing states of matter.

Using simulations observe what solids, liquids, and gases look like at the atomic scale. After observing the different states of matter at their atomic level, students will be able to conclude about the forces and attractions that exist...

After watching this simulation, students will be able to describe characteristics of the three states of matter. They will watch as atoms and molecules change between solid, liquid and gas phases.

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the...

An interactive simulation will heat, cool and compress atoms and molecules. Watch as they change between solid, liquid and gas phases. Recognize that different substances have different properties which will affect the temperatures for...

This resource explains the five states of matter and methods of changing from one state to another.

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...

Students will be expanding a study of phase changes after experiences with exploration of the three phases of matter. They apply what they have learned through freezing water and create a tasty ice cream treat.

This activity reviews of states of matter, then relates them to atomic movement as it is affected by attractions between atoms and the addition of energy. Latent heat and evaporative cooling are also topics covered. Multiple-choice and...

The heat of vaporization along with several other thermal properties are explained. Sample problems are given. Illustrations.

Learn how states of matter can change as heat is added to a system.

In this series of chemistry labs, students learn about the three states of matter by observing how molecules contract or expand as they change state.

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...

Help the Phantom choose a material and observe the changes at different temperatures in the molecule chamber. What happens to the elements or molecules as the temperature changes?

Find out how matter can change from one state to another.

Science experiment that demonstrates the four states or phases of matter: solid, liquid, gas, and plasma. Includes full list of materials, procedures, and scientific explanation of how you change water from a liquid state to a gaseous...
