This is a graduated cylinder. It is used to measure volume. This one measures volume in milliliters.
How do I read the volume of the liquid in the graduated cylinder?
See that curved line from the liquid? It's called the meniscus. When we're measuring liquids, we have to read the measurement at the bottom of the meniscus.
Can anyone tell me how we could measure the volume of an irregularly shaped object, such as a rock, using this graduated cylinder?
I think that we could pour water in the graduated cylinder and then measure it. Then, we could drop the irregular solid into the water in the graduated cylinder, which will make the liquid rise. Next, we could measure the liquid again and find the difference between the second liquid measurement and the first. That difference would be the volume of the object.
Excellent job! Kelly, it's your turn! Can you please tell us about beakers and droppers?
