Concentration and mass | Developing understanding | 14–16 years

Developing understanding is a series of resources that encourage learners to connect their thinking at the macroscopic, sub-microscopic and symbolic levels. In this worksheet learners are encouraged to think about concentration both observationally and quantitively, as well as how this can be represented using particle diagrams. As a result, learners will develop more secure mental models to support their understanding of this topic.
