1. Density Lab: Draw and title this data table in your journal:
Density Data Table:
Material
Radius (cm)
Length (cm)
Volume (cm3)
Mass (g)
Density (g/cm3)

2. Density Lab Procedure:
1) Measure and record the radius of each material 2) Measure and record the length of each material 3)Determine the volume of each material with the following formula: ∏ r2 x l or pie x radius2 x length 4) Measure and record the mass of each material 5) 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
