Lego Molecules
Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, learners build molecules based on the chemical formulas of common compounds.
Cornell University
The Making of Macromolecules
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...
