Density Lab:Draw and title this data table in your journal:

Material Radius (cm)

Length (cm)

Volume (cm3)

Mass (g)

Density

(g/cm3

)

Density Data Table:

Density Lab Procedure:

1) Measure and record the radius of each material2) Measure and record the length of each material3)Determine the volume of each material with the

following formula:

∏ r2 x l or pie x radius2 x length4) Measure and record the mass of each material5) Calculate the density for each material with the

following formula: D=m/v or density = mass/volume

6) Answer the analysis questions in your journal

Materials and their Densities

Material Density

Aluminum 2.9

Copper 8.9

Polyethylene 1.02

PVC 1.4

Nylon 1.2

Density Lab Analysis Questions:1) Which of the materials had the greatest

density and why? 2) Which of the materials had the least

density and why?3) Predict which sample(s) would float in

water.4) Describe how you could find the volume

of each material without measuring the radius and length.

5) Determine which type of investigation this lab would be classified as and defend your answer.

6) Graph your results and label the IV and DV.
