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...

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...

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...

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...

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...

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.

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 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.

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...

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

Given descriptions, scenarios, or illustrations, students will distinguish between the compressibility, structure, shape, and volume of solids, liquids, and gases.

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.

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

[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.

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...

Through this curricular unit, students are introduced to the important concept of density. The focus is on the more easily understood densities of solids, but students may also explore the densities of liquids and gases. Students devise...

[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...

By the end of this section, you will be able to state the common phases of matter; explain the physical characteristics of solids, liquids, and gases; and describe the arrangement of atoms in solids, liquids, and gases.

By the end of this section, you will be able to define and describe thermal expansion; calculate the linear expansion of an object given its initial length, change in temperature, and coefficient of linear expansion; and calculate the...

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

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.

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...

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."
