With most liquids, the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules. So the liquid "sticks" to the side of the container.
A few liquids have a "backwards" meniscus. An example is Mercury. If you put mercury in a test tube, it would be higher in the middle than at the edges.
When reading the meniscus in a graduated cylinder, you should ensure your eye level is parallel to the liquid level. The bottom of the curve of the liquid surface is the correct level to record. The meniscus is the curved surface due to water molecules sticking to the cylinder walls. Take the reading at the lowest point of the curve.
The student should pour and measure the liquid carefully until the meniscus reaches the 12.5 mL mark on the graduated cylinder. The volume is read at the bottom of the concave curve of the liquid.

You should always measure the volume of liquid in a graduated cylinder at the bottom of the meniscus, where the curve of the liquid meets the cylinder's surface. This ensures an accurate reading of the volume contained in the cylinder.
The property that causes water to curve is surface tension. Surface tension is a result of the cohesive forces between water molecules, creating a thin "film" on the surface of the water that resists penetration. This surface tension causes water to form droplets and exhibit behaviors like capillary action.
The curve on a graduated cylinder is called a meniscus. It occurs due to surface tension between the liquid and the container, causing the liquid to curve at the edges. When measuring volume in a graduated cylinder, the bottom of the meniscus should be used for accurate readings.
The liquid curve is called a meniscus.

Water in a graduated cylinder forms a meniscus due to the capillary action, which is the result of the water molecules being attracted to the walls of the cylinder. This causes the water's surface to curve slightly upward or downward at the edges, creating the meniscus shape.
