Text of Measuring
- Measuring How to be PRECISE and ACCURATE
- How to Measure MASS MASS the amount of MATTER in an object; measured in grams (gm) Triple Beam Balance
- Place an object on the pan.
- Slide the rider with the largest mass along its beam until the pointer drops below zero.
- Repeat the process on each beam until the pointer stays at zero.
- Add the masses on each beam to find the mass of the object.
- How to Measure VOLUME (Liquid Volume) The amount or liquid; measured in milliliters (ml) Graduated Cylinder
- A meniscus is the curve of the surface of the water in a graduated cylinder.
- Water "sticks" to the walls of the graduated cylinder, but only on the sides and not the middle.
- When you look at the surface, the water level is not straight its curved like a smile.
- Measurement should be at the BOTTOM of the meniscus.

- Read the meniscus at eye level in to get an accurate reading. read the meniscus at eye level.
- How to Measure LENGTH
- Most metric rulers have lines indicating centimeters and millimeters.
- The centimeter lines are the longer, numbered lines.
- The shorter lines are millimeter lines.
- When you use a metric ruler, line up the 0-centimeter mark with the end of the object being measured.
