Looking at the worksheet, I need to find the volume of liquid in the graduated cylinder shown in question 1.
First, I need to understand how to read a graduated cylinder. The key is to look at the bottom of the curved surface of the liquid (called the meniscus) and read the measurement at that point.
Looking at the graduated cylinder in question 1:
- The cylinder has markings from 0 to 50 mL
- The major markings are every 10 mL (0, 10, 20, 30, 40, 50)
- Between each 10 mL mark, there are smaller lines
Let me count the small lines between 0 and 10 mL to find the scale:
- There are 5 small lines between 0 and 10 mL
- This means each small line represents 2 mL (10 ÷ 5 = 2)
Now I need to find where the bottom of the meniscus is:
- The liquid level is at the 30 mL mark
- Looking more carefully, the bottom of the meniscus is exactly at the 30 mL line
Wait, let me look again more carefully at the image. The graduated cylinder shows:
- The liquid level appears to be at the 30 mL mark
- The bottom of the meniscus aligns with the 30 mL line
So the volume of liquid in the graduated cylinder is 30 mL.
Final Answer: 30 mL
Parent Tip: Review the logic above to help your child master the concept of measuring liquid volume worksheet.
