VSEPR Modeling Kit
Product Code : EL-PT-11143
Last updated: 6 October 2026
Quick answer: A modelling kit taking students from Lewis dot structures and the octet rule through to the geometric shapes of covalent compounds and polyatomic ions, answering why molecules with the same formula can have different shapes.
The driving question is a good one because students genuinely find it puzzling: why do molecules with the same molecular formula have different geometric shapes? Answering it requires moving from counting electrons to arranging them in space, which is precisely the step from Lewis structures to VSEPR.
The kit uses a systematic approach, having students first master Lewis dot structures and the octet rule, then extend that to the structures of covalent compounds and polyatomic ions. Lewis dot structures are described as models representing the number of electrons in the outermost energy level of an atom.
The pairing of drawing with building is the method. Student illustrations combined with physically building the molecular model representations is what makes the geometry stick: a structure that looks fine as a flat drawing becomes obviously wrong when the model will not assemble that way.
Including polyatomic ions matters, since charged species are where the electron bookkeeping is hardest and where most students lose track. The published objectives begin with writing Lewis dot structures for elements, molecules and polyatomic ions, but the list is cut off mid-sentence. The contents, class size and grade level are not stated; request them before ordering.
