If any experiment is done here in the United States but can't be repeated in europe, can the experiment be considered good science? Why or why not.
No, since it can't be repeated it is not good science..

What is the difference between Accuracy and Precision?
Precision is how close measurements agree with each other.
Accuracy is how close measurements are to the actual value you are measuring.

Describe in step by step detail how you could measure the volume of any irregularly shaped object.
Fill up a graduated cylinder with water. record the measurement. Put the irregularly shaped object in the graduated cylinder. Record what the volume increased to. Subtract the two recorded volumes and the remainder will be the volume of the irregularly shaped item.
