CHEMISTRY SCAVENGER HUNT
PURPOSE: to review the names and proper use of lab equipment
INTRODUCTION: During this activity you will be finding a series of pieces of lab equipment
and placing in on your lab bench and then showing the equipment to your instructor. You will
also be answering a series of questions to demonstrate your understanding of proper use of
equipment.
1) Find a test-tube tong, a beaker tong and a crucible tong. Place them on your lab bench
a) Give two reasons why you wouldn’t use beaker tongs to pick up a crucible that
was being heated at high temperatures. (2 marks)
Ans: Beaker tongs can not withstand the heat that crucible tongs can.
2) Find a 100 mL beaker and a 100 mL graduated cylinder.
a) Give one reason why you would use a 100 mL beaker instead of a graduated cylinder
and one reason why you would use a 100 mL graduated cylinder instead of a beaker
(2 marks)
3) Find a 250 mL beaker and a 100 mL Erlenmeyer flask.
a) Give two reasons why you might choose to use an Erlenmeyer flask instead of a
beaker (2 marks)
i)
ii)
An Erlenmeyer flask is used when we perform titrations
An Erlenmeyer flask is used when we want to mix chemicals together
4) What is a retort stand used for? (1 mark)
To hold equipment is place such as a titration apparatus.
5) You should ALWAYS wear safety goggles when conducting and experiment, why? Where
are the safety goggles located? (2 marks)
6) Where should you conduct a reaction that you know is going to produce a foul smelling
gas? Why?(1 mark)
In the fume hood so you could keep the smell as contained as possible.
7) Where is the dustpan and broom to sweep up broken glassware? Where do you put
broken glassware? Why? (2 marks)
8) Where is the eyewash station? (1 mark)
9) Why should you always pour a chemical you will be using into a beaker before pouring it
into a graduated cylinder? (1 mark)
10) Should you ever allow a chemical reaction to occur in a graduated cylinder? Why or why
not? (2 marks)
11) Where should you put any waste products from an experiment? (2 marks)
12) What should you do if you spill a hazardous chemical on your hand? (2 marks)
