What are the uses of mass and volume measurements?
Mass and volume are properties of matter.  Mass and volume can be
measured.  Scientists must be able to measure mass and volume accurately.  Then they 
can repeat their experiments and make predictions based on their
Mass and volume are just as important in science as colors are to art. 

What is mass?
Mass is the amount of matter in an object.  Mass is different from weight.  
This will be explained in the presentation
