The Enigma Machine Historical Investigation Lab
By Micah's Learning Resources
Station X: Breaking Enigma is an interactive investigation set at Bletchley Park in 1941. Students open one file, follow a map of linked evidence nodes, and work out how a team of mathematicians and codebreakers turned German radio traffic into intelligence that changed the Battle of the Atlantic. The file runs in any browser with nothing to install. What's inside - An interactive node map set at Bletchley Park in Buckinghamshire in 1941 - Linked evidence nodes covering Alan Turing and the Bombe, Admiral Karl Donitz and the Battle of the Atlantic, and a decrypted Enigma message - A Teacher's Guide with a three part lesson: The Problem, The Solution, The Result, with timed parts adding up to 40 minutes - A Cipher Exam quiz for checking what students took from the investigation - Investigation goals written as student tasks, so the map can be worked without a walkthrough How it works Students read a short briefing, then move around the map. Each node holds one piece of the story: who the codebreakers were, what the Enigma machine did, how the Bombe tested settings faster than a person could, and why broken codes decided which convoys survived. Students connect the nodes to build the chain from intercepted gibberish to usable intelligence, then answer the quiz questions on the Cipher Exam tab. Topics covered - Codebreaking and signals intelligence in the Second World War - Alan Turing, the Bombe, and early computing - The Battle of the Atlantic and the U-boat war - How intellige
