a rock changes when placed in water. Identify the independent and dependent variables. If the rock is placed in water‚ then it’s mass will be added to the original mass. The independent variable has to do with the amount of water put onto the rock‚ the dependent variable is the mass of the rock after it has been in the water. 3. Describe‚ in detail‚ a procedure to test your hypothesis. Identify the controlled variables. The controlled variables is the mass of the rock before it has gone into the

variable The variable is the important aspects of the research. In research the concept are measure from variable. Variable are anythings that can take on differing or varing values. it mean that the value of variable vary from person to person‚ time to time or place to place but the meaning of variable are same to all. Thus variable are the charactestics of person‚ groups‚ objects‚ ideas‚ feeling or other thing that researcher want to measure. Variables are thus anything that can take on differing
