Differences Between a Chemistry and Biology Lab

Chemistry and biology are two of the basic or pure sciences. As such, they study vastly different realms. Biology studies living organisms -- there are over 10 million species living on earth. In addition, biology classifies living organisms based on their features, and seeks to identify and understand DNA, the unique instructions contained within the cells of living organisms. Chemistry is concerned with the substances that make up matter, and their structure, composition and behavior under differing conditions. Chemistry focuses on atoms, the building blocks of all matter, and the forces that bind them; therefore, the lab for each science exhibits several differences.
  1. Purpose

    • The biology laboratory seeks to learn more about the components of the living organisms, how they work together as a whole and the environment in which each survives. In a chemistry lab, students or scientists determine how one substance -- based on its structure -- reacts with another. They attempt to measure and express the energy required or output in a given reaction. Chemists seek to understand the bonds between chemicals.

    Equipment and Supplies

    • A biology lab would be incomplete without a microscope.

      The two labs reveal many notable differences. A biology lab's central instrument is the microscope. Slides, cover slips, stains, droppers and specimens are in plenty supply. Notable as well are the many tools for dissecting organisms: scalpels, trays, magnifying glasses, scissors and measuring devices. Tools in a chemistry lab include a variety of specific and precise measuring devices such as a mass spectrometer, which measures the mass atomic composition of molecules. Other tools assist in chromatography, specialized filtering and separating of substances. Computers assist in calculations and measurements. Of course, a chemistry lab would be remiss without a myriad of chemicals and beakers.

    Reference Materials

    • Reference material is researched for each lab.

      Scientists and students performing laboratory work study reference material to set up or validate their experiments. Each scientist records his findings in a laboratory notebook. This is an extremely important proprietary reference. Extensive literature and research material are found in a biology lab, as they are needed to determine protocols for setting up and performing experiments. Biological classification charts, books and keys assist biologists and students as they classify organisms. A prominent reference material in a chemistry lab is the periodic table of elements. Material Safety Data sheets (MSDS) contain important information about chemicals and their hazards. A chemistry lab may contain volumes explaining atomic theories, equations and experiments testing them.

    Recording Results

    • Laboratory results are recorded in great detail in every branch of science. Background information, principle or theory put to the test, materials and procedure, precautions, findings, conclusion, cleanup and works cited are recorded in every lab. The primary difference between a biology lab and a chemistry lab record is in the expression of the findings. A biology lab will demonstrate findings with detailed diagrams and illustrations, whereas a chemistry lab expresses findings in equations detailing the reaction.
