2. What is Calibration?
Calibration of measuring device is distance between two closest lines (Not distance between two closest #!)

3. Not all graduated cylinders are calibrated the same way

4. ? capacity
of large graduated cylinder?
? calibration of large graduated cylinder?
1000 ml
10 ml

5. source
Calibration = ?
1 ml

6. Calibration = ?
1 ml

7. Calibration = ?
1 ml

8. Calibration = ?
0.2 ml

9. Here are some other pieces of lab equipment
Here are some other pieces of lab equipment. Can you figure out the calibration of each?

10. meter stick: two closest lines
are 1 millimeter apart

11. Calibration = ?
50 ml

12. Calibration = ?
25 ml

13. This is a quadruple beam balance

14. What’s the calibration?
0.01 gram

15. This is a buret The calibration is: 0.1 ml
[unlike graduated cylinder, numbers go down, so you read downwards]
The calibration is:
0.1 ml

16. calibration important?
So why is knowing
calibration important?
When you measure you measure to one place past the calibration.
You told me the calibration was 1 ml, so the answer has to go to 1.0, 1.1, 1.2, 1.3, etc
