[1] After getting into your groups, pick a name for your group!
[2] Come up to the front of the room and get two blocks, one made of wood and one made of aluminum. Handle the blocks as little as possible, and put them down on your desk as soon as you return. Predict which block has a higher temperature.
[3] Test your prediction by using your thermometer to measure the temperature of each block. Again, avoid handling the blocks while you are making these measurements. Record the temperature of each block.
[4] After measuring the temperature of each block, place each against the inside of your wrist. Do they feel as if they are at the same temperature, or does one feel colder than the other?
[5] After you have finished the steps above, ask John for the amount of water that your group should be using for the next experiment. After he has given you a value, take your graduated cylinder out to the water fountain in the hall, and measure out the required volume. Pour the water into your styrofoam cup. Record the volume of water that your group is using.
[6] Use your thermometer to measure the temperature of the water in your cup. Allow the thermometer at least 30 seconds to equilibrate. After the thermometer reading has stabilized, record the water temperature.
[7] Bring your styrofoam cup to the front of the room, keeping the thermometer in it. John will pour some hot water into your cup, after which the temperature will start rising. Watch the thermometer carefully, and record the maximum temperature that the mixture reaches.
[8] After the temperature has stopped rising, take your styrofoam cup and graduated cylinder back to the fountain, and use the graduated cylinder to measure exactly how much water was in your cup after the addition. After you have made this measurement, you can pour your water out.
[9] Report your group's starting temperature, maximum temperature, starting water volume, and total water volume to John.
