Parenting and Responsibility
Activity 1. Egg Experiment
Students pretend that they are pregnant for one week. As expectant parents, students keep a record of what they eat. (Encourage students to examine what they eat; alcoholic beverages should be reported.)
Each student is given a raw egg for which the student is responsible for one week. (It may be allowed to sleep in the refrigerator at night.)
Discussions during the week concerning the care of the egg might include: differences and similarities among the eggs; accidents—causes, responses; babysitting problems; peer pressures; family dynamics.
Students may wish to make special environments for their eggs (decorated boxes, cradles, baskets).
Final discussion should encourage each student to share what he or she has learned about parenting and responsibility.
