When you are measuring the volume of a liquid, the best way to do this is to use a graduated cylinder. There are different size graduated cylinders. The smaller the graduated cylinder, the more precise its measurements. This is because the graduations (measurement units) are smaller. As you increase the size of a graduated cylinder - the units it measures in increase. When using a graduated cylinder you want to make sure you are reading the measurement correctly. Watch the video below to review the correct way to use a graduated cylinder.
When measuring the mass of a material we use a balance. An electronic balance is the most common tool used.
