Students have two blocks that are the same size. They drop each block into a beaker of water. Why does Block 1 float and Block 2 sink?

• Block 1 is made of a different material than Block 2

• Block 1 is smaller than Block 2

• Block 1 absorbs more water than Block 2

• Block 2 has less mass than Block 1
