Lego Atoms and Molecules: Chemical Reactions
Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein)...
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...
Curated OER
Mighty Molecules
Students examine a PowerPoint production on molecules. Then they construct their own molecule and define what an atom, molecule, and matter is. They make a H2, HCI, and an H2O molecule. Finally, a drawing to accompany the actual model is...

How Structure Can Affect Properties Through Phase Changes
Middle schoolers discuss how changing the structure of atoms and molecules can change the properties of a substance. They brainstorm and review their own examples of phase change with the help of a phase change diagram. Students describe...
