If you believe one man's trash is another man's treasure, you don't want to miss the Houston Re-Market. Just bring something you don't want and take something you like. That's the idea behind the Swap at Houston Re-Market Saturday from 11 a.m. to 4 p.m. at the Station Museum of Contemporary Art on Alabama Street. There will also be art for sale made of recycled materials, live entertainment and food trucks.

Then celebrate art with free admission Saturday to the Museum of Fine Arts, the Contemporary Arts Museum and the Jung Center of Houston. There will be family art activities, Smilebooth photos and food trucks. It's all part of Museum Experience Day.

The American Diabetes Association Expo is free Saturday from 9 a.m. to 3 p.m. at NRG Center. Get free health screenings, watch cooking demonstrations and check out exhibitors.

Let your little ones learn about weather with KPRC's Anthony Yanez at the Bellaire City Library Saturday from 3 p.m. to 4. pm.
