Webquest lesson on the structure of DNA and discovery of DNA (watson, crick, franklin). I used this lesson with a middle set year 8 after a series of lessons on cells. Upload includes ppt (with some information on slides 4-9 that can be placed around the room to give students hints), webquest worksheets with questions and useful links for specific sets of questions provided, as well as extension questions. Note: access to laptops, ipads or computers required.
