The Fant Ewing Coliseum at ULM was packed with science projects for the Region III Science and Engineering Fair.
Students from middle school to high school competed for awards.
Organizers say the fair gives students an opportunity to think outside the box.
"It helps students to be creative to think on their own to think outside the textbook instead of memorizing stuff they try to come up with their own things," said Fasial Kaleem, a math professor at ULM. "I think it's a very good experience at a young age."
On Thursday, ULM will host the Social Studies Regional Fair.
Students in grades 4 through 12 from all schools in nine Northeast Louisiana parishes, and Monroe, will on hand to participate.
