In this lesson students distil essential oils from strongly-scented herbs such as crushed mint or basil.

They consider fragrance molecules by applying their understanding of the states of matter and the concept of volatility, before completing a simple distillation.

Students can then explore how different essential oils and nature identical fragrances can be combined to create the fragrances that make toiletries and cosmetics pleasant and distinctive.
