This project was carried out by the group as part of the International Year of Chemistry Challenge in 2012. The intention of the project was to work with students regarding how elements bond together to form compounds and then crystals and particles. A pilot project was run at a school in Surrey in October 2012 and the downloadable resource is the starting point, or building block, for the discussion on bonds, shape, crystals, particles.
A common chemical structure of a square based pyramid is the initial focus which is a simple structure to make but imperative to chemistry. It is used extensively in chemistry to represent a tetrahedral structure with a central atom surrounded by four atoms usually of a different element. This basic structure is one of the most common structures used in chemistry and structure of molecules is also part of the UK high school curriculum.
Depending on the audience this can be developed greatly in numerous ways including thinking of other compounds that may form tetrahedral structures/ introduction of the graphite structure.
