Curated OER
VSEPR THEORY: BALLOONS AND MOLECULES
Students 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.
Curated OER
If My Configurations are Correct
Students write the electron configuration of elements in the ground state. In this chemistry instructional activity, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.

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