Middle school students in public, private and charter schools and those who are home-schooled in Louisiana can participate in the 2015 Louisiana Science, Technology, Engineering and Mathematics Expo, hosted by Kenilworth Science and Technology Charter School in Baton Rouge on Feb. 28.

The theme of the 2015 expo is “Homegrown STEM in Louisiana.” The expo, an innovative alternative to traditional science fairs, will include demonstrations, games and robotics from students across Louisiana, a news release from Lambert Media said. Interested students can register for free at www.lastemexpo.org.

Isiah Warner, an LSU Boyd professor of chemistry and the university’s vice chancellor for Strategic Initiatives, will be the keynote speaker at the expo. “It is critical that we nurture that sense of curiosity and discovery that lies in so many of our young people,” Warner said. “We need more events like the Louisiana STEM Expo to provide encouragement, guidance and mentorship for students.”

Participating students can compete in chemistry, life sciences, physics, math or technology, and will work with their teachers and mentors to prepare a demonstration to present at the expo. Presenters will be judged by university and industry volunteers, and the winners and their teachers will receive prizes. Kenilworth is again inviting industry partners, nonprofits, local museums, higher education institutions and federal and state agencies to participate as exhibitors or sponsors. Last year’s expo attracted more than 500 participants from across the state. Sponsorships and partnerships for the 2015 expo also are available. For information, visit www.lastemexpo.org.
