Measuring Liquid Volume What is volume? Be sure you understand the scale on your graduated cylinder How is this scale increasing? What are the increments? Read bottom of the curve in the liquid or the “meniscus” The volume is 6.6 ml

When reading a graduated cylinder it is important to remember to read the bottom of the curved line or meniscus of the liquid. The scale on each graduated cylinder may be different. Can you identify the scale on the cylinder on the left? What is the volume? The graduated cylinder on the right is divided into increments of ___ ml, so the volume is ____ ml. Left – scale increases by 2ml and the volume is 12ml Right – scale increases by 1m And volume is 16ml

Reading the Meniscus Get down at eye level to read meniscus
