Location: Chicago, Illinois
Special Notes: "It doesn't take a genius to figure out that this apartment building burned to a crisp because it was old and made of wood. I don't want to witness another disaster like this one ever again! I've decided to build a
50-story deluxe apartment building in place of the old one, but I don't know what material to use. Can you help me?"
What material will you use to build the mayor's new skyscraper? Remember, the new building will be very tall and heavy, so the material you choose will be under a lot of compression.
