Pbs Learning Media: Molecular Shapes
In this interactive activity from ChemThink, students will learn about covalent molecules and how the VSEPR theory predicts the shapes of covalently-bonded molecules.
PBS
Pbs Learning Media: Chemical Bonds
This interactive activity developed for Teachers' Domain demonstrates how attractive forces between atoms create chemical bonds, resulting in the formation of molecules and compounds.
PBS
Pbs Teachers: Bottle Fountain Experiment
Demonstrate how heating expands air molecules by constructing a bottle fountain powered by air pressure.
New York University
New York University: States of Water
Use this resource to learn about the three different phases of water; solid, liquid, and gas. What happens to water as it changes into a solid or gas? Includes short and easy to do activity.
