Touch and Smell - Presentation

The presentation on "Touch and Smell" delves into the fascinating world of biology, specifically examining how humans interact with their environment through the senses of touch and smell. Students are encouraged to explore and understand the roles of skin and the nose in these sensory experiences. The lesson aims to answer fundamental questions such as whether the skin is responsible for the sense of touch, and if the nose is the body part responsible for smell. Through a series of interactive activities and thought-provoking questions, learners are guided to discover how our nose can detect a myriad of smells and how the sense of touch can be deceiving, leading to intriguing revelations about how our brains interpret sensory information.

Experiments in the presentation include testing the sensitivity of different skin areas, understanding how blind people read using Braille, and investigating the speed of smell diffusion with air freshener. The concept of diffusion is explained, and learners are given the opportunity to use their sense of smell to identify mysterious substances in boxes, highlighting the human ability to recognise an impressive range of smells. Additionally, the presentation touches on how various factors such as illness or age can affect our sense of smell. By the end of the session, students should be able to pinpoint the parts of the body responsible for touch and smell and reflect on how everyone's sensory experiences can differ.
