Seventh-graders come in to science class to find a file on their desks detailing a crime to be solved! As a demonstration, you simulate the restriction of DNA samples and separate them by electrophoresis. From the gel, learners can...

Investigate the relationships between different deep-sea organisms by DNA sequencing. A worksheet provides instructions for DNA sequencing and space to work. They simulate gel electrophoresis by cutting out paper "DNA strands."...

Ms. Strohfeldt did not omit anything when she designed this comprehensive lesson plan on DNA mutation and sex-linked traits. Begin with a pretest as an anticipatory set. Read a case history of the Clark family and the occurrence of...

Students perform restriction digests on DNA samples from four individuals, and then search for similarities between the individuals by running the restriction fragments on an electrophoresis gel.

Students engineer new organisms using biotechnology. In small groups, they write procedures, list benefits and drawbacks, and explain how their new organism might affect the environment. After creating their new organisms, they present...

Twelfth graders simulate a DNA fragment running through a gel electrophoresis in a class activity. Students work in teams as a DNA sample with each person on the team representing a fragment that moves through the gel at a specific speed.

Students conduct a variety of experiments to explore gel electrophoresis. For this biology lesson, explain how this process separate DNA and RNA. They discuss the practical applications of this method.

Ninth graders investigate what restriction enzymes do, and explain how a DNA sample can link a suspect to a crime.

Students simulate the steps involved in creating a DNA fingerprint by the RFLP technique. They analyze RFLP patterns to determine the parentage of a missing baby.
