TOPIC: Quadruple Beam Balance & Calibration

Do Now: What is the mass recorded on this balance?

This is a quadruple beam balance

What’s different between these 4???

1 2 0.2 0.5

Distance between closest lines (AKA – calibration)

Let’s measure the amount of liquid in each

Not exactly 10 not 11Estimate 10.3

Not exactly 6 not 7Estimate 6.5

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

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

Where would u draw the following meniscus?
