Atoms, molecules and elements | Developing understanding | 11–14 years

Developing understanding is a series of resources that encourages learners to connect their thinking at the macroscopic, sub-microscopic and symbolic levels. This resource aims to develop learners’ understanding of the basic particle model by extending it to represent elements that are made up of individual atoms and those that are made up of separate molecules. As a result, learners should develop more secure mental models to support their thinking about this topic.
