Just call us Mr. Peabody, because this week we’re all about time traveling in our own Way Back Machine:

1. To the Jurassic era
The Brookfield Zoo (First Avenue and 31st Street, Brookfield) is featuring “Dinosaurs Alive!” through October. Remote-controlled dinosaurs in the exhibit include the stegosaurs, the triceratops and others. From 10 a.m.-6 p.m. Exhibit admission is adults $17, seniors and children ages 3-11, $11 (includes general admission to the zoo). (708) 485-0263.

2. To the 1970s
The heyday of Led Zeppelin is here and now, thanks to the uncanny performances by tribute band Led Zeppelin 2. The band plays the House of Blues (329 N. Dearborn) tonight at 9 p.m. $13. (312) 923-2000

3. To the future
The long-running performance art/comedy show Blue Man Group hints at a technologically advanced future that is as much cold and alienating as it is funny. Catch it at 4 or 7 tonight at the Briar Street Theatre (3133 N. Halsted). Tickets: $49-$64. (773) 348-4000.
