Biological specimens in an elementary school science lab. A biological specimen (also called a biospecimen) is a biological laboratory specimen held by a biorepository for research. Such a specimen would be taken by sampling so as to be representative of any other specimen taken from the source of the specimen. When biological specimens are ...
A certificate of analysis (COA) is a formal laboratory-prepared document that details the results of (and sometimes the specifications and analytical methods for) one or more laboratory analyses, signed—manually or electronically—by an authorized representative of the entity conducting the analyses. This document gives assurances to the ...
Molecular biology – study of biology and biological functions at the molecular level, with some cross over from biochemistry. Structural biology – a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules. Health sciences and human biology – biology of humans.
The laboratory is a foundational example of hands-on, activity-based learning. In the laboratory, students use materials to observe scientific concepts and phenomena. The laboratory in science education can include multiple different phases. These phases include planning and design, performance, and analysis and interpretation.
The guidelines for lab notebooks vary widely between institution and between individual labs, but some guidelines are fairly common, for example, like those in the reference. [3] The lab notebook is typically permanently bound and pages are numbered. Dates are given as a rule.
Formal reports (ten or more pages and being too long to put into a memo or letter) also have a table of contents. Within an English-language book, the table of contents usually appears after the title page, copyright notices , and, in technical journals, the abstract ; and before any lists of tables or figures , the foreword , and the preface .
The 3 types of scientific experiments are: Controlled experiment – experiment that compares the results obtained from an experimental sample against a control sample, which is practically identical to the experimental sample except for the one aspect the effect of which is being tested (the independent variable).
It is their job to correctly perform a controlled experiment in which they determine the concentration of protein in the fluid sample (usually called the "unknown sample"). The teaching lab would be equipped with a protein standard solution with a known protein concentration. Students could make several positive control samples containing ...
