3Procedure; Part –Density of Unknown Blocks:
Your teacher will distribute various blocks around the classroom. Each group will determine the mass, volume and density of the block
they have been given. The data will then be compiled on the computer and students will complete their sheet using class data.
When all blocks have been recorded, students should use the chart below to determine the identity of each block. Circle whether each
block will sink or float in water.
