    Thomas Young and the debate about the nature of light: jumbled sentences activity Each student finds and scans into his smartphone a QR code hidden in the class revealing a paragraph of an introduction text to Young's double slit experience. The class group then collaborates in reordering the paragraphs in order to obtain the original text
