To prepare for the exercise, first print enough data recording tables for students in each group. NOTE: Activities one and two can be done simultaneously, each by half of the class broken up into groups of two to four students, or by all students if desired.
If the class will split the activity, separate the data tables accordingly.
Students performing activity two will need copies of Table 3 and Table 5.
For each group doing the land and sea ice activity, set out two 500 mL graduated cylinders, marking tape, a permanent marker, a ruler, and 20 ice cubes.
Cut out a two-inch diameter piece of styrofoam.
Use a hole punch or scissors to cut a small hole out of the middle for draining, and then place the styrofoam with the rest of the materials for the land and sea ice activity.
For each group doing the greenhouse gases activity, arrange two 500 mL graduated cylinders, plastic wrap, tape or rubber bands, marking tape, a permanent marker, and two thermometers.
Print figures 3-11, and the historic glaciation figure so that students can draw out ranges to visualize species range expansion.
