Before heading out for a packed day of museum hopping and sight seeing check out the Chicago CityPass at www.citypass.com. For one price of $59.00 ($49.00 for kids) it covers entrance fees to the Shedd Aquarium, Field Museum, Museum of Science and Industry, and Adler Planetarium among other things. It's valid for 9 days and a savings of almost 50 percent on entrance fees!
