1.	The mass of the wooden block was obtained, using the balance.
2.	The volume of the wooden block was calculated, after measuring the length, width, and height.
3.	The mass of the wood cylinder was obtained, using the balance.
4.	The volume of the wood cylinder was calculated after measuring the diameter, and the height of the cylinder.
5.	The mass of the metal cylinder was obtained using the balance. The volume of the metal cylinder was calculated after measuring the diameter and height of the cylinder.
6.	The mass of the water was obtained, by first obtaining the mass of the water with the graduated cylinder, then obtaining the mass of the cylinder, then subtracting the mass of the cylinder from the mass of the water + graduated cylinder.
7.	The volume of the water was measured to the 50-mL mark in the graduated cylinder.
8.	The mass of the 25 paperclips was obtained using the balance. 
9.	The volume of the 25 paperclips was obtained by the water displacement method. That is, the level of water was recorded in the graduated cylinder, the paperclips were added, the level of water was recorded again, and the difference between the water levels was the volume of the paperclips.
10.	The densities of these 5 objects were calculated and recorded.
