-Materials and Methods:
- Scale - Triple Beam Balance - Ten Different Cubes - Electronic Scale - Ruler - Water - Beaker

Method: 1.The cubed were gathered to make the hypothesis 2. The lighter cubes were weighed on the electric scale 3.The heavier cubes were weighed on the triple beam balance 4. The mass for each cube was determined 5.The volume of each cube was determined (length.width.height) 6.The density of each cube was determined (mass divided by volume) 7. The density of each cube’s predicted substance was found 8.if the densities were the same or extremely close (only a decimal away) than the hypothesis was right, and that was the substance of the cube.

-Qualitative Data:

 * Cube || Color || Texture/Weight || Opacity || Prediction ||
 * Cube # 1 || A mix of brown, gold, and red. || Smooth, with a small texture on the faces of the cube. The corners and sides are worn and rounded. It is pretty heavy, so we think that it is very dense. || None. || Predicted to be copper. ||
 * Cube # 2 || A silver color that shines in the light. || Smooth, all except for two sides that have a very rough and bumpy texture. The corners and sides are not very worn, and the cube is super light. || None. || Predicted to be aluminum. ||
 * Cube # 3 || A gold color that shimmers in the light. || Smooth, but there is a slight texture and, because the corners and sides are worn, it is slightly chipped. This cube is pretty heavy. || None. || Predicted to be brass. ||
 * Cube # 4 || A grey color, not that illuminating, very dull. || Very smooth on four of its faces, but on two faces, opposite of each other, it has a lined texture. This cube is super light. || None. || Predicted to be polypropylene. ||
 * Cube # 5 || A brown and red color that shines gold in a few places. || The cube is pretty heavy and chipping on the sides and corners, which are worn. It is smooth, but it has a slightly bumpy texture on its faces. || None. || Predicted to be iron. ||
 * Cube # 6 || Light brown striped with a darker brown in places. || Smooth on all of its faces. It is a light colored wood that is striped with a more brown color in places. It is very light in weight. || None. || Predicted to be balsa wood. ||
 * Cube # 7 || A very pure white color that does not shine in the light. || Smooth, but a small rough lined texture is on a three of its faces. It is a light cube, and the corners and sides are not worn, but sharp. || None. || Predicted to be polystyrene. ||
 * Cube # 8 || This cube is a wood that is half dark and half light, and does not shine in the light. || This cube is very light in weight, and half light in color and half dark in color. It’s a little bumpy, but the corners and sides are not worn. || None. || Predicted to be pine. ||
 * Cube # 9 || This is yet another wooden cube, striped dark and light. The corners and sides are not very worn. || This cube is heavier than the other wooden cubes, but it is still light in weight and it is striped dark and black, and has a slightly bumpy texture on its sides. || None. || Predicted to be poplar. ||
 * Cube # 10 || This cube is clear and see-through, but it does not shine in the light. || This cube is clear and the corners and sides are smooth, but not worn. This cube is super light and see-through. It is very smooth with no texture. || It is see through. || Predicted to be acrylic. ||

Table 5. Final Analysis

Using the research on the internet, and various pictures, we looked at all twenty of the possibilities and observed them carefully, then compared them to the blocks in our container. We found the density of all of the possibilities, and of our blocks, and attempted to match them up. When that didn't work, we used the process of elimination.
