Equipment
Calculators are convenient tools that allow people to perform arithmetic operations
quickly. A scientific calculator is useful for completing calculations that involve scientific
notation, trigonometry, logarithmic functions, exponential functions, and some statistical
calculations. Over the last 50 years, calculators have become affordable for most people
and are much more portable than a computer. A graphing calculator can complete the
same operations as a scientific calculator, but can also carry out more complex
calculations, graph functions and raw data, etc.
Scientific data can be collected using a variety of tools, but then it is often necessary to
determine whether relationships exist between two or more variables. By incorporating
graphing technology, a scientist can determine these relationships quickly. A graphing
calculator can be used to gather, view, and analyze real data. Probes are tools used to
take measurements of various characteristics of solutions such as temperature, pH,
elemental composition, and wavelength. Computers are used to either analyze or
interpret data. For example, a mass spectrometer is a machine that can analyze and
interpret the elemental composition of a compound.
Laboratory Safety
Be sure to use appropriate safety attire when working in a laboratory environment,
including chemical splash goggles, an apron or lab coat, and gloves. Additionally, you
should be prepared to use an eye/face wash in case of a laboratory accident. This device is
meant to help us in case chemicals or other substances are accidentally splashed on our
faces or into our eyes during the course of our investigations. There are several different
types of eye/face wash devices that are used in laboratories, and the correct usage
depends on the type available. Your teacher will instruct you on the appropriate use of
the equipment that is available to you in your laboratory. In general, you should
immediately ask someone to assist you if anything splashes in your face and eyes. You
should also rinse your face or eyes for at least 15 minutes, and use your fingers to hold
your eyes open if necessary, in order to ensure that the chemical has been thoroughly
rinsed out.
Fire Extinguisher
Fires are some of the most common lab accidents. You should be familiar with the
location and use of the fire extinguisher. Fires are classified by the nature of the fuel that
is burning. It is essential to use the appropriate type of fire extinguisher. Four classes of
fire extinguishers are recognized, and all of them are labeled to indicate the class of fire
for which they can be used. You should be familiar with all four classes:
Class A: Ordinary combustibles, like paper and wood
Class B: Organic solvents, like alcohol and acetone
Class C: Electrical fires
Class D: Flammable metals, such as sodium and magnesium
