Stone Soup is in the process of gathering work for their September issue which will be science themed.  Check out the many types of work you can submit:

• write up a science fair project or experiment for Stone Soup readers to try
• write a short essay about any area of science that fascinates you (i.e. comets, dinosaur coloration, the geology of a place near where you live, something about the weather, etc.)

Check out more details here.  All entries are due July 1, 2018.
