What is the purpose of a TEST TUBE

• To measure the volume of liquids

• used to hold small amounts of pre-measured

  substances.

• To grind substances into a fine powder
• To view microorganisms

What is the purpose of a DIGITAL BALANCE

• To measure the digital weight of an object
• To balance the digital data

• To balance the digital signals
• used to determine a smaller, lighter object’s mass.

What is the purpose of a TRIPLE BEAM BALANCE

• To measure the volume of a liquid

• used to determine the mass of larger,

  heavier objects

• To measure the height of an object
• To measure the temperature of an object

What is the purpose of a SCOOPULA

• used for transferring dry chemicals.

• used to determine the mass of larger,

  heavier objects

• used to determine a smaller, lighter object’s mass.

• used to measure how much heat energy is in an

  object.

What is the purpose of a WEIGH BOAT

• To serve food in restaurants

• To transport small aquatic animals
• used to weigh or transfer chemicals (usually dry).

• To store jewelry

What is the purpose of a PIPETTE

• To heat substances

• To store chemicals

• To grind substances into powder
• used to transfer liquid from one container to another.

  (Increments are very small – usually .25 mL per increment.)

What is the purpose of a BEAKER

• To cook food

• used to measure large volumes of liquid.

  (Increments are larger than a graduated cylinder – usually 25

  -50 mL per increment.)

• To store books
• To play music

What is the purpose of a GRADUATED CYLINDER

• To measure the temperature of a liquid

• To measure the weight of a liquid
• used to measure the volume of liquids. It is

  more precise than a beaker. (Increments are smaller than a beaker

  – usually 1 mL per increment.)

• To measure the density of a liquid
