Measuring Mass with a Triple Beam Balance

Mr. Boucher explains how to measure the mass of an object using a triple beam balance. He introduces the tool, describes its components, and demonstrates the process of balancing and measuring. The video emphasizes the importance of precision and units in measurement.

What is the main goal of using a triple beam balance?

• To measure the volume of an object

• To measure the mass of an object

• To measure the length of an object

• To measure the temperature of an object

Why is it called a triple beam balance?

• Because it has three pans

• Because it has three pointers

• Because it has three knobs

• Because it has three beams

What should you check before using the triple beam balance?

• Ensure the balance is on a flat surface

• Make sure the sliders are at zero

• Check the temperature of the room

• Ensure the object is on the pan

What is the first step in measuring the mass of an object?

• Place the object on the pan

• Adjust the smallest slider

• Check the zero point

• Adjust the largest slider

Which slider should you adjust first when measuring mass?

• The smallest slider

• The middle slider

• The largest slider

• The front slider

What does it mean if the pointer moves down when adjusting the slider?

• The mass is too light

• The mass is too heavy

• The balance is broken

• The slider is stuck

How do you fine-tune the mass measurement?

• By adjusting the middle slider

• By adjusting the pan

• By adjusting the largest slider

• By adjusting the smallest slider

What is the mass of the block if the sliders are at 130 grams and 6.7 grams?

• 136 grams

• 135.7 grams

• 137 grams

• 136.7 grams

Why is it important to include units in your final answer?

• To indicate the type of measurement

• To make the answer look complete

• To avoid confusion with other measurements

• All of the above

What should you do if your teacher asks you to round the mass?

• Round to the nearest whole number

• Round to the nearest tenth

• Do not round at all

• Round to the nearest hundredth
