Final answer:
To correctly read a graduated cylinder ensure it's clean and in good condition, fill it with the liquid you're measuring. Read the liquid level from the bottom of the meniscus at eye level.
Step-by-step explanation:
The correct procedure to read a graduated cylinder includes the following steps: firstly, make sure that the graduated cylinder is clean and in good condition. Fill the graduated cylinder with the liquid you're measuring, not just water, up to a certain mark. Always read the liquid level from the bottom of the meniscus (the curve formed by the liquid at the top). You should always read the graduated cylinder at eye level to prevent parallax error, which can skew your measurement. Lastly, it doesn't matter whether the meniscus curves upwards or downwards, you always read the level from the bottom of the curve.
