Analysis
1. Organizing Data

	D	F	H	M	P	10
Volume (cm^3)	54.18	71.28	95.83	238.65	219.488	298.96

2. Analyzing Data
    a. 10.1-4.3
         =5.8
    b. 298.96-54.18
         =244.78
    c.  Multiplying several length measurements together to find the colume will make the data less procision because the number of the sigfig will decrease as we multiply numbers. As it is inferred in the data and a. and b., data don't show any ratio.
3. Analyzig Data
    No; because we didn't do this lab in complete vacuum condition, acceleration, resistace against air, and velosity of objects would be different.

It can be inferred that ratio should be close to 1:2. but this data shows me that i have errors that changed my ratio. also it can be seen that if mass is increasing, than volume also increase except for block P
6. error can be maden when i measure the length, width, and depth. since human eyes are not maden to perfectly measure what is the length, quit few error can maden, and this will affect the data chart and volume. Moreover, when we were measuring the time for dropping blocks, there can also be few errors. First of all, our timer can show some error since we click the botton too fast or slow. secondly, since the area of the side that face the floor decide the resistance of air, there would be different measurement.

Extension
7. this experiment will show us about the timing that each students press the botton, and this explains the errors on the measuring the time
