1. 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

2. When reading a graduated cylinder it is important to remember to read the bottom of the curved line or meniscusof 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.

3. Reading the Meniscus Get down at eye level to read meniscus

4. Let’s Try it on Our Own! 53 ml 19 ml 73 ml

5. More Practice……….. 28.5 ml 6.8 ml
