To break the glass I held ice balls or whatever it's called and it should break the glass, Also saving the nerd you have to get the golden key from the last row of lockers (don't know which locker but definitely on the back row no doubts) drag it to the locker with a dinosaur poster on the locker will then open, once it's open a nerd will be hung up in the locker so then you click on it, Job done...!
