Beakers are used to

• measure exact volume with high accuracy

• hold small amounts of dry chemicals

• hold, heat, stir, observe, and measure approximate volumes of liquids

• hold solids while finding their mass

Name the lab equipment shown.

• flask

• test tube

• graduated cylinder

• pipet

What is so special about graduated cylinders?

• 
  They hold large amounts of liquids safely

• They are easily heated

• They measure exact volumes of liquids very accurately

• They allow us to examine a liquid when we are making observations

This is a pipet! What is the main function of this lab equipment?

• 
  Transfer small amounts of liquids

• Transfer large amount of liquids

• Transfer small amounts of liquids or solids

• Measure liquid volume

When reading volume on a graduated cylinder, where do we read the level of liquid?

• At the highest point the liquid touches

• The bottom of the meniscus (the curve)

• Halfway between the bottom and the top of the liquid

• Wherever we decide is best
