Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

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...

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....

Water is the source of life. It appears in poetry in both peaceful and torrential descriptions; it appears in earth science in its liquid, gaseous, and solid states. Combine these interpretations of our planet's most precious and...

Discuss Archimedes' Principle and fluid forces with your young scientists as they describe the relationship between mass, volume, and density during a series of engaging activities. They use the Participle Theory of Matter to explore the...

From molecules to nanotubes, an engaging unit explores the world of tiny science. Fifteen hands-on experiments and lessons engage young scientists as they learn chemistry. Discussions, worksheets, and data analysis reinforce the concepts...

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...

How did the earth become the mass that it is now? Your young scientists explore this question through the concept of density. Their inquiries consider the impact of gravity on the formation of planets. The culminating activity of the...

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 discover intermolecular attractions between neighboring molecules. These intermolecular attractions, or IMA, affect the behavior of liquids, solids, and solutions.

Students will look at what happens to different types of matter when they have a change of state.

A collection of cartoon animations that teach students what they need to understand about solids, liquids, and gases.

Students investigate the structure and parts of the atom, and learn about atomic mass and atomic number. They also explore the differences among solids, liquids, gases, and plasma.

[Free Registration/Login may be required to access all resource tools.] Explains how to describe matter in the solid state, about the properties of liquid matter and gases, and what the relationship between energy and states of matter is.

The differences between solids, liquids, and gases and the properties of each are presented in this lesson.

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

This lesson teaches students about how sound vibrations are transmitted through solids, liquids, and gases, and about how materials may absorb sound.

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

Learn about topics related to the material world. Each topic includes facts, a glossary, an interactive quiz, printable worksheets, an image bank, and web links.

[Free Registration/Login may be required to access all resource tools.] Explains what happens to matter when it freezes and the definition of freezing point.

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...

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.

Ever wonder why solid ice floats in liquid water? In this video lecture you will explore the special properties of water. Learn "the science behind how hydrogen bonds keep the ice in your glass (and the polar ice caps) afloat". At the...
