How does a polar molecule, H2O, compare with a nonpolar molecule, CO2? Young chemists learn the similarities and differences between their covalent bonds and properties. They practice applying prior knowledge in a new way to reinforce the concepts.
- Have pupils submit an exit ticket explaining the differences between covalent bonds of water and covalent bonds of carbon dioxide
- Challenge scholars to think of another metaphor for double bonds being stronger than single bonds
- Relies on prior knowledge of angles, chemical properties, and double bonds
- Links to related videos help extend the lesson
- Offers cues to pause the video and think through higher-level questions to take the concept further
