Lab Tools - Beaker

What is a beaker?

• A type of spoon

• A glass cup with a spout at the top rim to make pouring liquids easy

• A measuring tape

• A type of flask

Fill in the blank: The lines on the sides of a beaker indicate rough measurements, most likely _________?

• milliliters

• centimeters

• grams

• inches

What is an Erlenmeyer flask and what is it used for?

• An Erlenmeyer flask looks like a beaker, but it’s narrower at the top. This makes it easier to place a stopper in it so that you can save the contents for later. It is measured in milliliters as well.

• An Erlenmeyer flask is a type of test tube used for heating substances over an open flame.

• An Erlenmeyer flask is a flat dish used for evaporating liquids quickly.

• An Erlenmeyer flask is a measuring cylinder used for determining the mass of solids.

What is a volumetric flask and what is it used for?

• A volumetric flask is rounded at the bottom and has a long, skinny neck. It is used for more precise volume measurements than the Erlenmeyer flask and only has one mark for a very specific volume.

• A volumetric flask is a flat-bottomed container with a wide mouth, used for heating substances over a Bunsen burner.

• A volumetric flask is a cylindrical container with measurement markings all along its side, used for measuring approximate volumes.

• A volumetric flask is a conical flask used for mixing chemicals by swirling, and is not used for precise measurements.

Which lab tool is usually a rubber top that fits into flasks or test tubes, sometimes closed at the top and has small holes that allow them to be fitted to another piece of equipment?

• Stoppers

• Beakers

• Pipettes

• Burettes

Which lab tool is a piece of round, flat paper that is used for filtering solids or precipitates to separate them from liquids or solids? (Hint: Be sure to fold the filter paper in half first, then again, then peel back one layer before putting into the funnel)

• Filter Paper

• Petri Dish

• Beaker

• Graduated Cylinder

Which lab tool is used to measure liquids or solutions and is fairly accurate to the 0.1 place?

• Graduated Cylinder

• Beaker

• Test Tube

• Erlenmeyer Flask

When measuring a liquid or solution, be SURE to read the bottom of the ________, the curved surface of the liquid.

• meniscus

• pipette

• beaker

• flask

What is a burette and stand?

• A long, thin pipe with a valve and stopcock at the end

• A flat plate used for heating

• A container for storing chemicals

• A measuring cup

What is matter? Fill in the blank: Matter is anything that occupies ______ and has mass. If you can see, touch, taste, smell, or feel it, then it’s matter.

• space

• time

• energy

• light
