A Tasty Core Sample
Students can see the core sample
clearly if transparent straws are used.
Make one sandwich for every 2
students. Make the sandwich in the following order:
Have the first student place his/her
thumbs in the middle of the sandwich make it arch downward. Have
the other student use the transparent straw to take the core
sample. Carefully insert the straw and then slowly withdraw it
from the sandwich. Take samples in the middle and two end points
of the sandwich. Students
will be forming a syncline or downward pointing arch rock
Have the students cut the sandwich
in half. Taking the long toothpick attach one half the other part
of the sandwich in any fashion the students like. Take samples
students will be forming a fault. Record their observations.
