Can you Picture It?
On your trip home you see many interesting geological features. However, you are in such a rush to
get your fossil to the museum for the new exhibit, you do not have enough time to determine what
the features are. Instead you take detailed pictures to analyze at a later time. To find your
photographs, go to the 8th grade science page of the Cyberweb http://k-12.pisd.edu/cyberweb/ and
click on the Dynamic Earth icon. Go through the power point called “Geologic Features of Big Bend”
and answer the questions that are found on each slide and in the table below. This table will be
turned in with your final project.
