Horoscope experiment • Question: Are the Sun-Sign traits accurately associated with their respective birth dates? • Hypothesis: The proportion of students whose personality traits match their birth sign will be significantly greater than that due to chance.
Procedures: • Read the handout and decide which set of traits you identify with the most. • On the small piece of paper, write 3 things: • Your birthday • ONE code number for the traits that BEST describe you • Whether you think astrology can give accurate information about personalities (YES or NO) • Fold the paper ONCE and turn it in.
Procedures (continued) • Write “hit” or “miss” on the paper you received. (“Hit” if the birthday matched the code #, “Miss” if it did not) • Teacher takes tally by students raising hands. • Do similar tally of “yes” and “no.” • Fill out worksheet with your seat partner, to be turned in with pink sheet by end of class. If time allows, discuss your answers with another pair of students.
Is astrology science, non-science or pseudo-science? • Do Sunsets, Souls & Senses worksheet if time allows.
