Chemistry in Teaching Molecular Models: Construction of Models with Magnets

Molekulski modeli neizostavni su dio nastave kemije. Komercijalno dostupni modeli, osim što su skupi, uglavnom su premaleni za upotrebu u demonstracijske svrhe. U radu je dan prijedlog izrade kalotnih molekulskih modela od stiropora s magnetnim kuglicama u ulozi spojnica te pločastim magnetima za prikazivanje polarnosti molekula.Molecular models are indispensable tools in teaching chemistry. Beside their high price, commercially available models are generally too small for classroom demonstration. This paper suggests how to make space-filling (callote) models from Styrofoam with magnetic balls as connectors and disc magnets for showing molecular polarity
