Molecular Geometry with Balloons
Background Molecular geometry can be tricky for students to grasp. Two-dimensional representations of molecular geometries predicted by the valence-shell electron-pair repulsion (VSEPR) model can be difficult to comprehend. Three-dimensional models, however, give students the opportunity to view and manipulate models as needed, making molecular geometry much easier to understand. In this activity, each balloon represents […]
The Carbon Cycle
Background You may not even be aware of it, but you contribute to the carbon cycle every day. If you ride in a car, take a train, or fly in an airplane, you contribute to the production of carbon dioxide. The fruits and vegetables you eat were probably shipped in a vehicle that produced carbon […]
