You’ve just arrived to science class and you sit down with your lab group. On your desk is a mysterious box and some supplies for measuring differentobjects, including a graduated cylinder, ruler, thermometer, and digital balance.
Suddenly, you notice your teacher standing next to your lab group, looking frantic. She says to your group, “someone has locked the field trip permission slips in that box! We can’t go to the zoo unless you can get them out! If you are able to unlock the box before the end of the period, you don’t have to take tomorrow’s science test.”
