Fingerprinting

Human fingerprint patterns are the result of layers of skin growing at different paces, thus causing the layers to pull on each other forming ridges. Here, groups of learners see how patterns and fingerprints assist scientists in a...

No two people are exactly alike, and nothing proves that fact more than our fingerprints. Offering a series of fun educational activities, the second lesson in this series engages children in solving the mystery of who took the candy...

From crime to paternity, DNA fingerprinting has revolutionized how the world views inherited traits. Science sleuths investigate the facts about DNA profiling through a variety of activities. The Teacher's Guide includes printable...

The chances of a DNA mismatch occurring in DNA fingerprinting is one in a billion. Here learners see how using the differences in people's DNA, specifically Short Tandem Repeats (STRs), cutting them out using restriction enzymes, and...

Show your class why restrictions aren't always a bad thing. In the third segment of a four-part series, the instructor develops the idea of restriction enzymes. Pupils learn how scientists use restriction enzymes in DNA analysis and DNA...

Students examine the principles of electrophoresis. They evaluate both the agarose and polyacrylamide system of molecular separation. In order to bring the concepts of genetics and evolution full circle from DNA to protein, students...

Learners discuss methods used by forensic scientists and the basics of DNA and how it can be used to identify an individual after reading an article from The New York Times.

Students study DNA fingerprinting and how it is used in criminal investigations.  For this DNA lesson students interpret DNA fingerprints, explore the uses for fingerprinting and see the limitations of DNA testing. 

Students explore the history of fingerprinting and DNA identification. In groups, students are assigned topics to research such as the history of fingerprinting, the problems of fingerprinting, the development of DNA and the problems...

Students explore DNA fingerprinting. Students discover how DNA fingerprinting is done and judge the validity. They evaluate the use of certain prints in courts and address the ethics of establishing a national database of fingerprpints.
