VSEPR THEORY: BALLOONS AND MOLECULES
High schoolers listen to the teacher introduce VSEPR theory and explain molecular geometry. They use balloons to visualize the shape of orbitals. Students create visuals of molecular orbitals with strings and balloons.

Pauli's Magical Water
Students predict the shape of molecules using VSEPR theory. In this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.
