You will need: 1. A selfie stick 2. Cable or string 3. A3 laminates of the attached file 4. A phone (we used a school Android phone we use for app development) 5. Toilet roll tubes covered in random 1 and 0s

Print and laminate the ‘Journey of a selfie’. Cover the toilet roll tubes. Connect the phone to Google Photos. Suspend string or cable across the ceiling of the classroom or corridor with the ‘data packets’ (toilet rolls) at various points. Then attach the laminates in order scattered along the wire. At the start of the ‘journey’ invite the year 6 students to take a selfie, then show them how this becomes an image that can be sent through the Internet. When they reach the end of the ‘journey’ the image will be on the white board!

Tips: Use the student helpers to take the year 6s and parents along the journey. Have a student press F5 in the classroom to refresh the images every minute or so. Level: Beginner

Teaches: Image representation, data compression, binary, networking, Internet
