This document discusses different metric measurement prefixes and units for length, mass, volume, and density. It explains how to measure the mass of an object using a triple beam balance by leveling the balance to zero, placing the object on the balance, and moving weights to level the balance again and recording the total weight. Volume is measured for regular shapes using length x width x height, and irregular shapes use water displacement by recording the water level before and after placing the object in water. Density is the amount of matter in an object compared to the space it takes up, with water having a density of 1 g/ml, and the formula D = m/v.

3. Length
• Length - the distance between two points

4. Mass
• How to use a triple beam balance
• Mass - amount of matter in an object
• Weight - the force of gravity on an object
• level the balance to zero
•put the object on the balance
•move the weights to level balance to zero again
•add up the amount on the weights

5. Volume
• Regular shaped - - - l x w x h
• Irregular shaped - - - use water displacement
• Volume - the amount of space an object takes up
• record level of water in a graduated cylinder
• put the object in
• record how much the water level rises
• the amount it rises is the volume of the object
