-Materials

<Digital Balance
<10 diffrent cubes
<magnet
<one person to use their five senses.
<quarter
<computer

-Methods:

1. Smell and scratch the block.
2. Research on every possible identity(with wikipedia).
3. Measure the mass of the block with a digital beam balance.
4. Put a magnet on the block to see if it is magnetic.
5. Measure the length, width and height and multiply them together to find the volume.
6. Find the density of the object.

-Hypothesis:

1. Copper, because it smells and feels like a penny, which is copper.
2. Platinum, because it is light, and not magnetic.
3. Quartz, it has the color of quartz, and strength, and the look of quartz.
4. Acrylic, using the process of elimination for it.
5. Iron, because it smells like a quarter, which is iron and is heavy.
6. Poplar, using the process of elimination for it.
7. Nylon, because it is light and smells like new clothes.
8. Balsa Wood, because it is light and wood.
9. Mahogany, it has the tiny holes and color(a little darker than the others).
10. Polyvinylchloride, because its a flexible plastic.

4. The density of block #4 is 21.9g/15.6 cm3 = 1.4g/cm3.
5. The density of block #5 is 130.0g/15.6 = 8.3g/cm3.
6. The density of block #6 is 5.73g/15.6 = 0.4g/cm3.
7. The density of block #7 is 19.57g/15.6 = 1.3g/cm3.
8. The density of block #8 8.3g/15.6 = 0.5g/cm3.
9. The density of block #9 12g/15.6 = 0.8g/cm3.
10. The density of block #10 19.5g/15.6 = 1.3g/cm3.

-Research on Cube Possibilities (Citations Also, MLA):

Copper- Cube #1 is copper because it smells ike a penny which is made of copper, it is not magnetic like copper, and has density of 8.9g/cm3 which is close to copper.
Aluminum- Cube #2 is aluminum because it is a light metal with a color like aluminum foil. It also has a density of 2.9g/cm3 which is close to aluminum.
Quartz- Cube #3 is quartz because it looks like a quartz, it is the only irreguraly shaped object, it is the only mineral. Plus it has a density of 2.9g/cm3 which is close to quartz.
Tin- Cube #4 is tin because it is a metal and our research shows that tin has a density of g/cm3 which was close to the density we got of 1.4g/cm3.
Iron- Cube #5 is iron because it is a metal and our research shows that iron has a density of 7.87 g/cm3 which was close to the density we got of 8.3 g/cm3.
Poplar- Cube #6 is poplar because it is a wood and our research shows that oak has a density of 0.5 g/cm3 which was close to the density we got of 0.4 g/cm3.
Mahogany- Cube #9 is mahogany because it is a wood and our research shows that mahogany has a density of 0.705 g/cm3 which was close to the density we got of 0.8 g/cm3.
