Introduces topics of forensic science including fingerprints, trace analysis, drug analysis, arson, explosives, serology, DNA, questioned documents, and bloodstain patterns. In addition, specific science topics will be addressed such as matter and properties, significant figures, chemical reactions, organic versus inorganic compounds, spectroscopy, mass spectrometry, chromatography, and electrophoresis.
This is an excellent and fun option for someone needing a science course. It is a wonderful alternative to traditional physical science, chemistry, physics, or biology courses. The student will learn some chemistry, physics, and biology; and then immediately see how the science is applied in the profession of forensic science. Although the course cannot replace the rigor of a traditional science course to develop a solid foundation for a student interested in becoming a scientist, it can serve as an introduction to science through forensic application. In addition, because many "advanced" science topics are introduced (i.e., chromatography, electrophoresis, spectroscopy, and mass spectrometry) it can also complement the studies of students greatly interested in science.
The course contains 40 lessons with each lesson having a video (~20 min), an accompanying PowerPoint file, worksheet, and review video. There are also 8 quizzes, a mid-term and final exam. In addition, 50+ short bonus videos are available showing physical evidence, techniques, and chemical instrumentation of the forensic scientist. This is a meager attempt to bring the laboratory to the student by making available videos I made years ago when I had access to a forensic laboratory.
