Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

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, 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...

Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Discover atoms and molecules which make up matter, motion of atoms and how to measure the mass, volume and density of matter.

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.

This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals...

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...

[Free Registration/Login may be required to access all resource tools.] Discusses elements, atoms, compounds, molecules, and crystals. Looks at mixture and different types of them.

Atoms and molecules come together to create matter. What happens to the weight of matter when it is frozen? Can matter be destroyed? Check out these activities to clearly understand how this works.

When two or more atoms combine they give rise to a molecule. A molecule can be made up of many atoms of the same element. There are 112 elements known to man, so can you imagine the different permutations and combinations of molecules...

A video and a short quiz on the parts of an atom, the periodic table, and molecules.

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...

Given scenarios, descriptions, or illustrations, the student will determine the properties of water that affect chemical and biological systems.

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."

Matter is anything that has mass and occupies a space. In this site you will find a lot of illustrations and interactive activities dealing with matter.

This PDF is fill in the blank notes, activities and graphic organizers on kinetic molecular theory.

Why does the shape of a molecule matter? Learn about how the shape of the molecule not only determines the molecule's properties but also whether it reacts or not. This tutorial reviews of VSEPR and molecular geometry.
