Your class has gone on a field trip to the History of Computers Museum to find out how technology has changed in the last one hundred years. You and your best friend have been looking at an exhibit for so long that you've lost track of your class and your teacher. It's almost time to go so you must race through each exhibit and find them before the bus leaves to go back to the school!

You also might want to jot down any information you think might be important. Once you have all five clues, enter them in the computerdatabase below to find your class so you can go home. Make sure you type the entire answer and press enter to see if you are correct. Start the timer below the floor plan now!
