science class the week of 2- 9

in science class we took around seven different rock samples and preformed tests on them to find the hardness, fracture, cleavage, luster, magnetism and flamability. also we weighed them and found the volume. to find the volume we took a beaker with a hole in the side and filled it up to the top. then when the water stops flowing out of the hole; you drop a rock into it with a graduated cilender and find the ml. that came out.
