Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

Discover how the periodic table tells the story of its elements. Learners begin by studying the makeup of several mixtures. Their analysis leads to a discussion of elements and the periodic table. As they dig deeper, they understand the...

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,...

Ready to introduce the realities of molecular geometry to chemistry pupils? Use a logic-based interactive! Perfect as individual practice, the puzzles explore the bond angles and repulsions present in three common molecular shapes.

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

What's the matter? Gas, solid, liquid, or plasma. The presentation covers how to describe and identify matter, changes in matter, types of matter, measuring matter, particles of matter, Democritus, and John Dalton's Atomic Theory.

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...

This lesson focuses on atoms and elements including what they are, the chemical symbols for elements, and the placement of elements on the periodic table. A link to a test is provided.

[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.

Short slide show provides basic information about drawing Lewis dot structures for covalent compounds. Starts with anatomy of the atom, and then shows the relationship between atomic particles and the Periodic Table of Elements. Offers...

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...

In this activity, students construct models of molecules using marshmallows and gum drops.

[Free Registration/Login Required] Discover the composition of matter and the relationship between matter, atoms, and elements. Students will learn the differences between elements and compounds, and how molecules are formed. Chemical...

Kids learn about organic chemistry including the importance of carbon, organic molecules, compounds, hydrocarbons, synthesis, and functional groups.

[Free Registration/Login Required] Explore the composition of air and learn about the different atoms and molecules that we breathe every day.
