Using VNTR Analysis to Identify Guilt at a Crime Scene
Students collect DNA from cheek cells. They compare and contrast the processes of DNA replication and PCR. They discuss how this information can be used to determine guilt at crime scenes.
Curated OER
Fingerprinting
Students discover the basics of fingerprinting and how it identifies a person. They create their own fingerprints and compare them to classmate's to determine that no two people have the same identity because of fingerprints. Then they...

Genes: The Building Blocks of Life
Students examine various topics on genetics. Students explore the Internet to gather information on genetic testing, genetically engineered food, forensics, DNA and cloning. They research and determine the best way to fund each of the...
Curated OER
Genetic Engineering/Biotechnology
Learners create a paper model of a plasmid and insert a DNA molecule that contains a specific gene into the plasmid. They complete an actual transformation involving E. coli bacterium and relate the two activities to one another.

How do things flow in and out of a cell?
High schoolers revise thier partner's essay. They also write the second draft of their essay for homework. Students use the Protein Explorer web site to visualize molecules, ATP, DNA, proteins and lipid bilayer. They are able to see...
Curated OER
Genetics 3 Translation
Ninth graders first summarize the process of translation, and then they identify and restate the processes of DNA replication, transcription, and translation in their own words. They also define the purpose of each and identify what the...
Curated OER
Who Done It?
Students work in groups to solve various murder mysteries using DNA evidence to implicate suspects. Teams compete to solve the crimes the fastest, while using various scientific methods to accomplish their task.
Curated OER
The Case of Regulation in Cells
After your biologists have learned about transcription, translation, and gene regulation, they work in a small group to create a poster of a system that serves as an analogy of the gene regulation process. They share their creations with...
Curated OER
Using Amino Acid Sequences to Show Evolutionary Relationships
Compare protein fragments, count amino acids, and use the information to explore common ancestry. The resource mentions a student worksheet, however, a separate printable worksheet is not provided. The exercises are written into the...
Curated OER
Bacterial Transformation
Students discuss a bacterial experiment they previously performed and complete a pre-assessment. They participate in a lecture discussion given by the teacher through PowerPoint and then complete a cartoon worksheet and post-assessment.
Curated OER
DNA and RNA Structure and Transcription
Students compare and contrast the structure of RNA and DNA.They summarize the process of transcription and translation. The instructional activity uses an inquiry model and the use of codes in DNA.
Curated OER
Cell Structure And Function
In this biology worksheet, students respond to 13 multiple choice questions related to cell structure and function. They identify which are microfilamets and which have a cell wall. Students also describe what chloroplasts are and their...
Curated OER
How do Restriction Enzymes Work?
Students discover how restriction enzymes work, while learning the importance of restriction enzymes in studying DNA structure.
Curated OER
Molecular Medicine Comes of Age
Young scholars simulate the roles of employees of two fictional pharmaceutical companies to analyze how human genetic variation at a molecular level helps scientist better understand and treat disease. They explain the molecular...
Curated OER
Extraction of DNA from Onion
Pupils experiment with DNA by isolating it from plant tissue. They investigate whole onions to prepare DNA. They complete the experiment to examine the structural characteristics of DNA.
Curated OER
How is Foreign DNA Inserted into Organisms During the Genetic Engineering of Crops?
Students examine the positive benefits and negative consequences of genetically modified organisms following a lecture covering key biotech concepts and techniques. Students then conduct and experiment comparing the travel rate of...
Curated OER
DNA Extraction From a Variety of Tissue Samples
Students, working in cooperative groups, extract very impure samples of DNA from a number of tissue samples. They determine how the samples can be preserved and how they are similar.
Curated OER
The Molecular Evidence for Evolution
High schoolers discover the structure of DNA, and determine how genetics have supported rather than refuted Darwin's ideas.
Curated OER
DNA Replication
Students work with a partner to answer any unanswer questions on their review sheet. They work in groups of 4 to make flash cards as study aides. Students play a review game for the remaining of the class period. The winning team...
Curated OER
Controlling the Code: Molecules at Word
Learners investigate how cells determine which genes will be expressed and which will be silent. In this genetics lesson, students use on-line resources to complete a worksheet and gather information about gene regulation. Lesson...
Curated OER
Time Conceptualization
High schoolers use this activity to establish a new mode of reference to the conceptualization of time. To present hominid evolution in terms of millions of years and endosymbiosis of eukaryotes in billions of years carries little...
