This is the official web site for the Illinois Junior Academy of Science 
Region 11 Science Fair. The fair is organized by the Joliet Diocese Science Teachers Association (JDSTA).

The JDSTA Region 11 Science Fair gives students a valuable learning experience. Each year, young scientists from Catholic and private schools (Grades 7-12) pursue specialized fields of science by working on individualized research projects, either as part of their core curriculum or through independent study. These projects broaden scientific awareness and allow students to delve deeply into areas of their own special interests -- giving them a chance to explore, to gather information, to arrive at conclusions and to present ideas in a competitive public forum.
