This lab will go in your lab book. Follow the directions below to complete the lab.
Purpose (put into lab book)
The purpose of this lab is to determine the relationship between the mass and volume of copper wire.
Background (put into lab book)
The wire is a cylinder. Copy the formula for the volume of a cylinder in your background.
The diameter of the wire is 4.04 mm. The radius and height must be in the same unit when using the volume formula!
Hypothesis (answer in a complete sentence in lab book)
What do you think will happen to mass as the volume of the wire increases?
What graph type do you think you will get when you graph mass (y) vs volume (x)?
Procedure (summarize in lab book)
Pick 6 copper wires of different lengths.
Measure the length of each wire using the ruler.
Measure the mass of each wire using the balance.
Calculate the volume of each piece showing your calculations in your lab notebook. (the length of the wire is the same as the height of the cylinder).
Data (copy data table into lab book, do NOT draw the pictures, they are there for you to read the measurement from)

Length (cm)
(Measure the length of each wire from the picture and write that measurement in the data column below)
Mass (g)
(Measure the mass of each wire from the picture and write that measurement in the data column below)

Calculations (show all your calculations for volumes of the 6 wires in this section of your lab book)
Graph (sketch in lab book)
Using LoggerPro, generate a graph of mass (y) vs. volume (x). Email me for a copy of the link in which you can download LoggerPro for your computer. You may NOT graph this relationship by hand. It is necessary to have an equation for the line.
Sketch the graph from LoggerPro in your lab notebook making sure you include all the necessary parts (title, labels and numbers on axes, best fit line).
Identify the graph type and include the equation of your line.
Conclusion (write as three paragraphs in lab book)
P #1 - Restate the purpose and describe what the procedure was.
P #2 - State what you have learned based on the graph. Was your hypothesis correct? State the graph type and equation.
P #3 - Discuss any errors that could have affected the data and suggest how to fix them.
