Science week 2013 posters and quiz

A set of 10 posters to support science week 2013 theme of invention and discovery. Each poster has a qr code to take pupils to a link to help answer the questions for the quiz/challenge. The answers can also just be found on the internet. I am planning to run it as a quiz/challenge where the posters will be displayed around the school for the pupils to find and complete the challenge sheet in order to win an Easter egg
