In a graduated cylinder, the water or liquid will tend to pull its surface up the side just a bit. This curved shape is call the meniscus. You should read the level at the lowest point of the meniscus, in the center. Turn the cylinder so that the markings are toward you, so you can see the low point of the meniscus behind the markings to get your measurement. There are a few liquids which want to pull away from the edges, which will thus have an inverted meniscus. For these, you would read the high point.
The meniscus is the name for the way that water forms a concave curve at it's surface. This is because of the cohesive and capillary properties of water.
You must read from the bottom of the meniscus. In a narrow, graduated glass cylinder, water has a slightly domed surface, with the centre being higher than the side, so giving a false reading if the centre height is taken.
Since the surface of water rises up to the sides of the cylinder, the low point is in the center of the surface. (Volume is assumed unless boiling or melting points are stated)
AnswerA meniscus is when the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules. This causes the liquid to "stick" to the side of the container, creating a curve. The volume must be read at the bottom of the meniscus.
It is the Fahrenheit scale.
Water in a glass graduated cylinder adheres to the sides of the cylinder, forming a meniscus which is an upward curve. When reading volume in a cylinder, look at the meniscus at eye level. Read the volume at the bottom of the curve.

One method of determining whether the pH and alkalinity are properly adjusted to produce stable, non‑corrosive water is with the Baylis Curve. Plotting the pH and alkalinity of the water on this chart will indicate whether the water is corrosive or not. If the point where the pH and alkalinity cross is below the curve (dark gray area) the water is corro­sive and will attack metal tanks and pipes in the system. If the point is above the curve the water is not corrosive but does have excessive amounts of alkalinity present, which will cause the formation of lime scale in the lines. This scale formation can restrict the flow of water in the line if al­lowed to build up over a long period of time and can be as bad for the system as corrosive water. When the point falls within the dotted lines or on the curve itself, the water is stable and will not cause corrosion problems.

Get a measuring jug that will hold the marbles easily. Half fill the measuring jug with water. Note the volume reading on the measuring Jug scale (measurement A). Add the marbles. Note the new water level reading on the measuring jug scale (measurement B).Subtract measurement A from measurement B, the answer is the volume of the marbles.
