Wear closed toed shoes.
Do not cut yourself on the rocks, they can be sharp.

Triple Beam Balance
Predict the densities in a journal without lifting them.
Set a rock onto the triple beam balance.
Find the rocks mass using it.
Record the mass in your journal.
Repeat steps 2-4 for the other rocks.
Fill a graduated cylinder to 50ml.
Put the rock into the cylinder.
Record the new volume and subtract it from the original and that's the volume.
Repeat steps 6-8 for the other rocks.
Calculate the density for each rock using the equation mass/volume= density.
Clean up workspace.
