Year 10 Computer Science Visit to Bletchley Park
On Friday, 3rd July, we had the opportunity to visit Bletchley Park with the Year 10 Computer Science groups. As the home of Britain’s wartime codebreakers, it was a fascinating experience that helped bring to life many of the concepts we have studied in Computer Science, particularly cryptography, encryption and the history of computing.
Our day began with a guided tour of the site. We visited the Mansion, which housed the Government Code and Cypher School, as well as several of the famous huts and cottages where codebreakers worked during the Second World War. Seeing the original offices, equipment and documents gave us a much better understanding of how the Enigma code was broken. We also learned about influential figures such as Alan Turing, Gordon Welchman, Dilly Knox and Mavis Lever, whose work helped lay the foundations for modern computer science.
After the tour, we watched a film that explained the important role Bletchley Park played during the war. It was fascinating to learn how the intelligence gathered by the codebreakers supported the Allied war effort and contributed to saving millions of lives.
Before lunch, we took part in an interactive workshop on encryption and cryptography. Through demonstrations and practical activities, we explored how information can be protected and how encrypted messages were decoded during the war. The workshop highlighted the importance of mathematics, logical thinking and problem-solving in keeping information secure.
One of the most enjoyable parts of the workshop was completing the hands-on cryptography challenges. We used a key to unlock a secured box, which helped us understand how encryption keys protect information. We also used iPads to decode messages using different cipher techniques. These activities gave us an insight into the challenges faced by wartime codebreakers and demonstrated the importance of accuracy and analytical thinking.
After lunch, we had time to explore more of the site and visited the Age of AI exhibition, which connected Alan Turing’s pioneering ideas to modern developments in artificial intelligence through the work of fellow codebreakers Donald Michie and Jack Good. The interactive exhibits were particularly engaging, allowing us to identify AI-generated images and explore how AI can be used to analyse satellite data. We also learned about the AI Safety Summit that was hosted at Bletchley Park in 2023.
Overall, the trip was both educational and inspiring. It helped us develop a deeper understanding of encryption and computer science, while showing how these fields have influenced history and continue to shape the world today. We are very grateful to the Computer Science Department and the staff who organised this memorable and enriching experience.
