Station #2: Swirls and Cracks Activities 1) Make both a rubbing and a sketch of the swirls from the bedrock sample. (sample provided in the kit) Label your results (Zoophycus- Schoharie grit worm). Rubbing: Sketch: 1
2) Make several observations to describe the properties of the solid bedrock you see at this station: (other examples- Solid bedrock, Bedrock) 3) Measure and record the acute angle(on the picture) between the joint cracks with a protractor. _______° 4) a) Watch the Acid Demo (here) Remember-Marble is made from Limestone which is made from Calcite(CaCO 3 ) Dolostone is made from Dolomite* b) Perform an acid test on the back of the hand sample in the kit. ____ Acid bubbled right away with lots of bubbles ____ Needed to be scratched with a nail to get it to bubble, minor bubbling ____ Never bubbled CaCO 3 + 2HCl → CaCl 2 + CO 2 + H 2 O Calcite Hydrochloric Calcium Carbon Water (Calcium Carbonate) Acid Chloride Dioxide CaMg(CO 3 ) 2 + 4HCl → CaCl 2 + MgCl 2 + 2CO 2 + 2H 2 O Dolomite (Magnesium/Calcium Carbonate) magnesium chloride 5) What is the difference between a trace fossil and a body fossil? 6) Is the fossil evidence observed at this station a trace fossil or a body fossil?
