What does a triple beam balance measure in an object?

• volume

• height

• mass

• width

Which tool would you use to measure the volume of water?

• Ruler

• Thermometer

• Graduated Cylinder

• Triple Beam Balance

Why do scientists measure water and other liquids by volume?

• To find out how heavy the liquids are

• To see how tall the liquids are

• To know the amount of space the liquids take up

• To determine the color of the liquids

How do you measure the volume of a liquid using a graduated cylinder?

• Look at the top of the liquid and write down the number.

• Read the number at the bottom of the curve, called the meniscus.

• Measure the height of the liquid with a ruler.

• Shake the cylinder and then read any number.

How do you measure the mass of an object using a triple beam balance?

• Place the object on the balance and read the number on the screen.

• Add weights to the balance until it tips over.

• Move the sliders on the beams until the balance is level, then add up the numbers.

• Pour water into the balance and see how high it goes.

• Degrees

Which unit is used to measure volume?

• milliliters

• grams

• kilograms

• degrees
