Help students understand how alcohol affects the human body with this engaging, interactive digital lesson designed for KS3 Science and PSHE. Rather than simply telling students not to drink alcohol, this lesson explores the biology of ethanol, how it affects the nervous system, brain and liver, and the long-term health risks associated with alcohol misuse through interactive, self-checking activities. It is based on the original middle school version but adapted for the UK National Curriculum and common KS3 topics.
