Paleontology students work the site under the supervision of the park paleontologist. An educator is on-site daily to answer questions and assist the staff. After four years, there is still much to be learned about the site. Examination of the bones shows that almost none have been chewed on. Method Practice paleontological field techniques.
Procedure Give each student one of each type of cookie, two paper towels, and six toothpicks.
Have the students first work on the hard cookies to extract the chocolate chip or raisin using only the toothpicks. If they break a toothpick so that it is no longer sharp, they can no longer use it. It must be discarded. After 3 to 5 minutes, stop and find out if anyone was successful in extracting anything. Now let them work on the soft cookies using the same constraints and rules.
