1. TOPIC: Quadruple Beam Balance & Calibration
Do Now: What is the mass recorded on this balance?

2. This is a quadruple beam balance

3. What’s different between these 4???1 2
0.2
0.5
Distance between closest lines (AKA – calibration)

4. Let’s measure the amount of liquid in each
Not exactly 10 not 11
Estimate 10.3
Not exactly 6 not 7
Estimate 6.5

5. Let’s measure the amount of liquid in each
Since it’s right on the line we have to add a zero, so 10.0
Since it’s right on the line we have to add a zero, so 6.0

6. Look at the quad beam balance from the do new again.
What should the correct measurement read…

7. Where would u draw the following meniscus?
