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.

Take a look at some molecules that are so cool, they're polar! Scholars examine the effect polarity has on a molecule's shape and charge. Change up the view and choose between an opaque or transparent molecular surface, complete with...

There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.

Protons and neutrons and electrons, oh my! Physical science scholars get hands-on with interactive atomic modeling. Starting with a simple helium atom, participants create and name ions, then build isotopes. Questions throughout the...

Glucose is a simple sugar and a molecule that can be illustrated through modeling. Scientific investigators with visual impairments use hands-on models to reconstruct the process of bonding molecules. The tools used in this activity are...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

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.

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...

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,...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...

Finally, an electronegativity resource your class will be strangely drawn to! Skilled scientists manipulate interactive puzzles to gain an understanding of common electronegativity values. The great thing? You can conduct the lesson...
