Yesterday you measured the mass, volume, and weight of objects with various tools.  Today you are going to be doing a similar activity.

Please move through the stations that have been set up to find out the weight, mass, and volume of the 10 cubes.  


Tips:

VOLUME:

For the volume in cmᵌ, do the equation length x width x height

Example:  length 2 cm, width 2 cm, height 2 cm

2 x 2 x 2= 8 cmᵌ

DENSITY:= 

Density equals mass divided by volume.  The equation is D=  M/V.  Using a calculator, divide the mass of each object by its volume.  There are two possible numbers depending on whether you use ml or cmᵌ.  Just stay consistent.  

Example:  Mass= 8 grams ,  Volume = 4 cmᵌ

8/4 = 2    The density is 2 (g/cmᵌ)



When finished, answer the following questions:

1.  What was similar about each of the cubes?  Were you surprised by the similarities?

2.  What was different about each of the cubes?  Were you surprised by the differences?

3.  While the cubes all have the same volume, why was their weight and mass different?

4.  What new understandings do you have now about density?
