Problem Overview:
The task involves measuring the volume of liquid in each graduated cylinder shown in the image. Graduated cylinders are used to measure the volume of liquids, and the key is to read the bottom of the meniscus (the curved surface of the liquid) at eye level.
Solution Approach:
1.
Identify the Meniscus: The meniscus is the curved surface of the liquid in the graduated cylinder. For water and most liquids, the meniscus is concave (curves downward).
2.
Read at Eye Level: Always read the volume at the bottom of the meniscus, ensuring your eyes are level with it to avoid parallax error.
3.
Determine the Scale: Each graduated cylinder has markings that indicate the volume scale. Pay attention to the intervals between the markings.
4.
Record the Volume: Write down the volume in milliliters (mL), including the unit.

Volume: 150 mL
Final Answer:
\[
\boxed{
\begin{array}{cccccc}
3 \, \text{mL} & 45 \, \text{mL} & 70 \, \text{mL} & 110 \, \text{mL} & 350 \, \text{mL} \\
12 \, \text{mL} & 25 \, \text{mL} & 35 \, \text{mL} & 3.5 \, \text{mL} & 150 \, \text{mL}
\end{array}
}
