Section 1.1

If you put a liquid in a glass container it usually curves at the edges. This curvature is called the meniscus. To get an accurate measurement, you measure the level at the horizontal center. This is the part of the meniscus that is at the very center. With meniscus that curve up at the edges you read the “bottom of the meniscus.”

Remember that the only way to read a meniscus properly is to have your eyes at the level of the top of the liquid. Read the bottom of the meniscus.

DIRECTIONS: Give the volume in the following graduated cylinders.

1. 2. 3. 4.

1. ____________ mL 2. _____________ mL 3. ______________ mL 4. ________________ mL
