This video tutorial teaches how to measure mass using a balance scale. It begins with an introduction to the concept of mass and the tools used for measurement, such as balance scales. The tutorial explains the importance of ensuring the scale is balanced before taking measurements. It provides step-by-step examples of measuring the mass of a glue stick and a carrot, emphasizing the process of adding weights until the scale is balanced. By the end, viewers will understand how to accurately measure mass in grams using a balance scale.

What is the primary tool used to measure the mass of small objects?

• Thermometer

• Balance scale

• Ruler

• Protractor

What is a common mistake when using a balance scale?

• Placing the object in the wrong container

• Using the wrong units

• Not letting the scale balance before reading

• Not using enough weights

What is the first step in measuring the mass of an object using a balance scale?

• Add weights to the scale

• Read the scale immediately

• Calibrate the scale

• Place the object in one container

How do you know when the balance scale is ready to be read?

• When the object is heavier than the weights

• When the scale is completely balanced

• When the weights are equal

• When the scale tips to one side

What was the mass of the glue stick measured in the lesson?

• 15 grams

• 20 grams

• 10 grams

• 5 grams

When measuring the carrot, what was the initial weight added to the scale?

• 5 grams

• 10 grams

• 15 grams

• 20 grams

What was the final mass of the carrot as measured in the lesson?

• 42 grams

• 40 grams

• 46 grams

• 44 grams

Why is it important to ensure the scale is balanced before adding up the weights?

• To use fewer weights

• To save time

• To prevent the scale from breaking

• To ensure accurate measurement
