Start a stress-free weekend with free yoga lessons in NorthPark’s courtyard. Staff from Cooper Aerobics Center will be giving free classes Saturday mornings at 9:30 all summer starting this weekend. Space is limited, so you’ll need to RSVP—and bring your yoga mat, or a towel.

Catch a Broadway tunes and classic swing concert courtesy of “TAKE 5” at Temple Emanu-El this Saturday at 3 p.m. The performance is the final act in the temple’s 2009 Art Series, and tickets are available online.

Saturday night you can catch “CSI: Ancient Egypt,” a free lecture about what skeletal remains tell us about people who lived 5,000 years ago. The 7:30 p.m. talk will be in SMU’s Fondren Science Building, room 123.
