Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
In this activity, students learn how DNA analysis is changing the way we fight crime and disease. Students begin by exploring the use of DNA fingerprinting in criminal investigations. They conduct a Web activity that teaches them how DNA fingerprinting is done. Then, working in teams, they examine and interpret the DNA fingerprints of a group of individuals. Next, students review the location and role of DNA in the body. They learn how a single mutation in DNA can affect health -- for example, how a mutation in the gene that controls red blood cells can result in sickle cell anemia. Finally, students learn about the significance of the Human Genome Project and the promise it holds for curing disease.
1. Show the Forensic DNA Analysis video. Discuss the following:
2. Explain that DNA is playing an increasingly important role in criminal investigations. Tissue evidence is now routinely collected during these investigations in hopes that it will provide genetic clues linking suspected criminals to crimes. Have students explore the Create a DNA Fingerprint Web activity to learn how DNA fingerprinting is done.
3. Give each team of students a set of the DNA Fingerprint Photos. Ask them to interpret the fingerprints and compare their answers to those of other teams when they are finished. Provide a key of correct answers. Or, ask:
4. If time allows, have students read the How DNA Evidence Works Document and discuss.
5. Ask students:
6. Have students do the Journey into DNA Web activity. Then ask:
7. Show the video A Mutation Story. Discuss the following:
8. Explain that scientists have been working to learn all the DNA sequences of human genes so that they can better understand human disease. This research is called the Human Genome Project. Show the Human Genome Project video and discuss the following:
