Resource
Aspirin screen experiment
Get students aged 16–18 running their own organic synthesis on a computer or tablet before taking part in the real thing. This resource also features an in-depth practical guide and a set of worksheets covering the theory.
Resource
Limestone weathering
This activity is designed for students aged 11-14. It can be used to reinforce work on the reactions of carbonates with acids as well as the chemical weathering of rock.
