The Museum of Discovery, 500 President Clinton Ave., Little Rock, presents its next-to-last educational event through March 5 before it closes April 2 for renovations that include three new galleries, a new entrance, and redesigned exhibit areas.

Engineers Make a Difference celebrates the imagination, analytical skills, inventiveness and design abilities of engineers. Visitors can participate in hands-on experiments (like turning milk and vinegar into a solid bioplastic and experimenting with pH) from the Public Broadcasting System shows NOVA and FETCH and record their favorite MOD memories on the Comment wall. 

All activities are included in Museum admission ($8 for adults, $7 for children ages 1-12). To make group reservations call Beth Nelsen at (501) 396-7061.
