WHAT FLOATS YOUR BOAT? Registration is open through Oct. 9 for a STEM Saturday program on boats, buoyancy and density from 9 a.m. to 12:30 p.m. Saturday, Oct. 11, at the Lyons Center at Joe Brown Park, 5600 Read Blvd., New Orleans.

Students will work with STEM professionals and college students on projects to learn about the principles of buoyancy and density and understand why things float. They will learn about Archimedes’ principle and buoyancy by participating in hands-on activities that demonstrate that even though a material is denser (heavier) than water, it can still float.

The event is sponsored by the Southeast Louisiana Chapter of the American Association of Blacks in Energy. The fee is $60, but a limited number of free slots are available for students who receive free or reduced-price lunch vouchers. To register, visit www.stemnola.com.
