just think of something that happened at your school, or even just a spirit week, and write about it as if it were a headline/news report.
here's an example of something that happened at my school in this format
breaking news!!!
for spirit week at (school), students were asked to use "anything but a backpack!" students came to school carrying their books in baby strollers, guitar cases, and even large red wagons! We will keep you updated on the absurd book-carriers students are using
or if it were something personal,
breaking news!!!
(school) student (name) has been caught sneaking out of class to go eat lunch with his boy friend, with whom he does not have the same lunch period! His teacher is completely clueless! We will keep you updated!
