Using the Triple Beam Balance

A triple beam balance is used to measure​ (a)   , in grams, which is the measure of ​ (b)   of a substance. This is different than ​ (c)   which is the measure of ​ (d)   on the substance.

• mass
• the amount of matter
• weight
• the force of gravity

Place the following in order of zeroing out the triple beam balance:

1) ​ (a)  

2) ​ (b)  

3) ​ (c)  

• Move each slider so that it is at zero.
• Check to see that the zero lines are aligned.
• If needed, adjust the adjustment knob.
• Place the object on the pan
• Move the sliders to the right

Which slider do you start with when measuring the mass using a triple beam balance?

• 100 g slider

• 10 g slider

• 1 g slider

• Any slider can be started with.

How do you know that when the 100 g or 10 g sliders are in place?

• When the arms swing down.

• When the arms swing up.

• When the slider clicks into place.

• When the zero lines are aligned?

How do you know when the triple beam balance has reached the mass of the object?

• When the arms swing down.

• When the arms swing up.

• When the zero lines are aligned.

• When the sliders click into place.

The video makes an error in the final measurement. All measurements need to be made to the ​ (a)   , which is the ​ (b)   place for this triple beam balance.

• first uncertainty
• hundredths
• hundreds
• tens
• ones
• tenths
• accurate measurement
