Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

What has more energy than a room full of pupils after a fire drill? This lesson plan! Explore the changes in energy during different chemical reactions, discover why some reactions feel cold and others feel hot, and tackle the concept of...

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

Students canvass the water cycle in the seven lessons of this unit. The processes of the water cycle and the cyclical nature of water is emphasized inthis unit.

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

Students learn about solids, liquids, and gases in this interactive slide show. Animated cartoon characters explain concepts having to do with properties of matter. A self-checking quiz follows the lesson.

Light travels as transverse waves and can travel through a vacuum. Sound travels as longitudinal waves and needs to travel through a solid, liquid or gas. Read about the properties of light and of sound, and learn the differences between...

By the end of this section, you will be able to interpret a phase diagram; state Dalton's law; identify and describe the triple point of a gas from its phase diagram; and describe the state of equilibrium between a liquid and a gas, a...

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.

[Free Registration/Login may be required to access all resource tools.] Freshly baked bread and cherry pie are two delicious parts of any meal. What happens to the ingredients that go into the bread and the pie as they are heated in the...

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...

Through an instructional video, games, and activities, students explore three types of change matter makes: physical change, in which only the shape of the matter changes; physical phase change in which matter changes to a different form...

Have you ever seen static electricity cause a spark of light? What is that spark? What about lightning, the Northern Lights, or the tail of a comet? All of those things and many others in fact, 99.9% of the universe -- are made of...

This lesson focuses on the states of matter: solids, liquids, and gases. It also discusses the Kinetic Theory of Matter, Thermodynamics, Triple point, Phase Change Graphs and the Heating Curve of Water. It provideds adrawing of a heating...

In the States of Matter module, students further explore the concept that anything on earth that has mass and takes up space is matter. This exercise introduces students to solids, liquids and gases, the three most common states of...

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...

This lesson will compare the relative kinetic energy possessed by molecules in different states. It is 1 of 2 in the series titled "Kinetic Energy and States of Matter."

A tutorial reviewing the states of matter and the effects of heating and cooling matter in the different states. (Note: some of the links may not load in the archived version of the site.)

Did you know the ancient Greeks first identified the three states of matter? Read about how the molecules differ in solids, liquids, gases, and plasma. View photographs and watch how the molecules move in each state. If you're really...

In this interactive module you will be introduced to a unit on fluid dynamics. Learn how an object's density relates to its mass and volume by completing various activities and interactives.

Set sail with Oleif, the Viking. Make his boat move by learning all about matter and particles.

This lesson will introduce a phase change diagram, and show how a substance changes from one phase to another. It is 1 of 3 in the series titled "Phase Changes."

A video and a short quiz on the periodic table of elements and how it is organized.

This lesson will introduce a phase change diagram, and show how a substance changes from one phase to another. It is 3 of 3 in the series titled "Phase Changes."
