Discover experiments, a survey and other activities to teach 11–16 year olds about surfactants and acid–base chemistry in the context of hair care and shampoos.

In this set of activities, students explore a variety of key chemical concepts relating to hair care, shampoos and conditioners. Designed for 11–16 year olds, the resources place ideas about surfactants, acids and bases in an everyday context, using activities ranging from practical experiments to role play and a class survey. Stimulate and involve your students in learning about:

The features and ingredients of different shampoos
The structure and properties of hair
How shampoos and conditioners work
Shampoo as an example of acid–base chemistry and surfactants in use

Each activity includes instructions for students, as well as editable worksheets and resources available for download.
