Shapes of Molecules—Geometry of Central Atom

How is a molecule's shape determined? Explore bond angles, lone pairs, and VSEPR theory through a logic-based activity. Chemists pull together information about the major molecular shapes, then use it to solve puzzles.

Instructional Ideas
  • Pair the puzzles with a full molecular geometry interactive PBS lesson and activities
  • Group students and assign them a particular geometry concept to explore
Classroom Considerations
  • Point out which angle is which in some of the more complex shapes for learners in the early stages of molecular geometry
  • Uses great example molecules for each of the featured shapes 
  • Presents content in an interesting and easy-to-deliver format
  • None
