Lesson Plans
- Using DNA to Identify People # Learning objectives: Students will learn what DNA fingerprinting is, what it is used for, and how it is used in paternity testing and forensics. Students will see how this technique actually works in lab. Students will learn how to analyze the gels used in this technique to match babies to parents, and crime scene evidence to suspects.
- Life after Death: Some Genes Remain "Alive" # In this lesson, students will analyze an informational text intended to support reading in the content area. The article explains what happens to certain genes after an organism has died. This lesson also introduces a related video that explains how the fields of Genetics and Biotechnology have affected the field of Forensic Science. By reading the article and viewing the video, students will learn about new discoveries in gene function after death and the impact varying fields of science have upon another. This lesson includes a note-taking guide, text-dependent questions, a writing prompt, answer keys, and a writing rubric.
- How to be a Molecular Biologist the Easy Way # This lesson plan details the ethical concepts of biotechnology and allows students to explore basic concepts of manipulating and analyzing DNA in a classroom setting. The lesson takes the students through a discussion of controversial topics related to molecular biology and biotechnology, DNA isolation, restriction digestion of DNA, gel electrophoresis, and DNA cloning.
- Personal DNA Testing # A lesson with multi-media components from PBS/NOVA that focuses on DNA testing, including techniques, purposes, and considerations for biotechnology and human decisions regarding health. Students will learn about single nucleotide polymorphisms, how they are used in science, and how they are being used in the medical field. Students will apply this knowledge by looking at a mock data set and probabilities to inform medical recommendations.

Text Resource
- Some Genes Remain "Alive" for Days After the Body Dies # This informational text resource is intended to support reading in the content area. Researchers from the University of Washington, led by microbiologist Peter Nobel, found that hundreds of genes reawaken and function in mice and fish for up to four days. Nobel also discovered that these genes are responsible for responding to stress and regulating the immune system. There were also others that are important for a developing embryo being used and these shouldn’t be needed after birth. In addition, the genes may also be linked to increased cancer in organ transplants and scientists are hoping to use the information in forensic science to better estimate a time of death.
Tutorial
- DNA Sequencing Using the Sanger Method # DNA sequencing is a technique for determining the complete sequence of bases (As, Ts, Gs, and Cs) for a particular piece of DNA. Sequencing is relatively time consuming, as the process must be done to fairly short lengths of DNA at a time. This tutorial will help you to understand the process of DNA sequencing.
