As you consider what you're doing for Earth Day (it's tomorrow, by the way), add this to the list: The Museum of Science and Industry is offering free admission all day (9:30 a.m.-4 p.m.).

While you're there, make sure to check out the recently re-opened exhibit, "Smart Home: Green + Wired." Not only will you be able to tour the "Greenest Home in Chicago," but you'll see 40 students from Hyde Park's Bret Harte Elementary School helping to plant a sustainable garden for the home (they'll be there from 10 a.m.-noon). If that doesn't get you in the Earth Day spirit, nothing will. If you get inspired, we've found a list of ways you can do your part throughout the week.

Before Wednesday's through, be sure to take advantage of some Earth Day deals at local bars and restaurants. And make plans for another stop on the Chicago eco-tourism circuit while you're at it.
