The Enigma Machine

The Enigma Machine

In the Enigma Machine lesson, students will learn the intricacies of cryptography used in World War II to convey secret messages to soldiers in the field. Students will start by looking at a simple shift cipher and will create their own cipher wheel to send and receive encoded messages. Students will then learn about the German Enigma Machine and will run a web-based emulated version to better understand how it works. Finally, students will discover how the Allies broke the Enigma’s code in WWII and the effect that had on winning the war. Part of this lesson was adapted from a lesson plan by Northern Illinois University. Topics addressed: Basic cryptography and relevant vocabulary Shift ciphers and how they encode plain text using a simple algorithm The Enigma Machine and its impact on the outcome of World War II Primary CT concept: algorithms. Students will consider different algorithms used in various forms of cryptography, including the very complicated logic involved in the Enigma Machine. Students will be able to: Explain why cryptography is necessary to keep messages secret Explain the algorithm of a simple shift cipher Understand at a high level how the Enigma Machine operates Understand at a high level how the Enigma Machine was defeated Materials: PowerPoint presentation Shift cipher template and instructions Suggested lesson breakdown: 10-15min – introduction to cryptography 10-15min – students create and test cipher wheels 5min – discussion on shift cipher 7min – Enigma Machine video 10min – Enigma Machine web emulator 10min – Cracking the Enigma Machine video

Microbit Board Game Project

Microbit Board Game Project

This resource was used for Year 7 Computing following a unit involving learning about variables, selection, iteration and random number generation using the Microbit. They loved playing the game, especially as they helped to create it! The idea is to have them use the Microbit as part of the board game. They will program in a dice function for shaking the Microbit, and other features for when they press Button A or B. The game works similarly to Snakes and Ladders. Button A moves the player either forwards or backwards, 6, 4, or 2 spaces (picked randomly by the program), and Button B moves the player up or down by flashing up to 3 up or down arrows (again randomly). Instructions were given via a worksheet, where the first page (two of the tasks) were given in the first lesson and the final one was given at the start of the second. When they had finished their program they could then download it to the Microbit and play their game. My students ended up with between 10-25 minutes playing time depending on how quickly they programmed their game. They can provide their own playing pieces from pencil cases etc. and the board is provided (A4 printout is fine). TES wouldn't let me upload the code but the screenshots are in the powerpoint slides so can be made up quickly.

Microbit - "The Next Big Thing" unit (18 lessons with resources)

Microbit - "The Next Big Thing" unit (18 lessons with resources)

This is an 18 lesson unit of work around Microbits, combining programming using the online microbit interface and electronic components. The components I used were sourced from http://microbit-accessories.co.uk but you could make your own or source from elsewhere as well. Helpsheets are provided for each of the electronic components. The students each have a workbook for the whole unit divided into sections that can be easily marked by the teacher, with opportunity/space for student reflection and response. Students start off learning about microbit theory, i.e. safe handling (static) and polarity, inputs, outputs and programming structures IF statements and loops. They then need to design the "next big thing" - a device that solves a problem, using the microbit. They will need to produce a design brief and circuit diagram. Once they have built it, there is a lesson on gathering user feedback and evaluation. At the end of the unit, they have the opportunity to create a business pitch for their new device. This is a great end to the unit as each student/group gets to share their creation to the rest of the class, with prizes for the best entries (at teacher's discretion!) The course mainly links towards the D&T criteria (with reference to the relevant criteria at the end of each powerpoint) but could be used in Computing as well.

Coding and Algorithm Activity Cards Bundle

Coding and Algorithm Activity Cards Bundle

This bundle provides a great opportunity for students to have fun whilst learning the fundamentals of coding and algorithms. When students use these action cards in an ‘Unplugged’ environment they are executing instructions socially and collaboratively using commands and concepts applicable to the real world and computer programming. Your students will love coding and creating algorithms by programming each other to undertake real world tasks in the classroom. They will continually collaborate to refine their code making it as efficient and effective as possible. Students will frequently, fail, revise and succeed using these cards building resilience and learning through trial and error. Most commonly students use these “action” cards to create instructions to follow as if they were a robot in pairs or teams. One as the coder and the other is the machine or device that must explicitly follow the instructions. Next, they can use these with real robotic and coding languages such as Sphero, Dash and Dot and Scratch to visualize and perform a set of actions before entering those instructions into the device. This package includes 10 challenges for students to begin straight away but they will begin creating challenges and missions in no time using just the room and resources in which they are located. Also include Boolean operator cards for students to explore how search engines operate.

micro:bit of Things

micro:bit of Things

https://sites.google.com/view/microbitofthings This is a website for anyone who has their hands on a micro:bit (microbit) and wants to know what they can do with it. I created the site to publish notes on projects that I am working on with my pupils, so this site will be of interest to teachers who are looking for ideas and advice that will enable them to exploit the capabilities of their micro:bits. The projects have been piloted with children in Key Stage 2 or Key Stage 3 and many are now embedded into the STEM curriculum at my school. They have been designed with tight budgets in mind.
