The exercise they will go through of working backwards from measurements to age should help them understand how scientists use carbon dating to try to determine the age of fossils and other materials.

Unlike people, you can’t really guess the age of a rock from looking at it.

Make a data table and, at regular intervals (you decide how long), record the time on the clock and the volume of water in the graduated cylinder.

Stop after about 30 minutes, unless Frosty has completely melted earlier.

Students should complete the Analysis section of the lab sheet, which will be used as part of their assessment.

Advise students to read through the case first so that they understand what they should do.

    In eight months using the service, Riccardo, who is 32 and works for an ad agency, has let eight visitors crash at his apartment, of whom he’s hooked up with five, for a 62 percent “success rate.” If you count the additional two who climbed into bed with him for a cuddle and then fell asleep, the percentage climbs even higher.
