Curated OER
Cracking the Code of Life
Students examine the concept of DNA. They work together to extract DNA cells from their classmate's cheek. They answer questions related to what to do with their DNA now that they have it.
Curated OER
The Ladder of Life
Students explain the concepts of what DNA is and where it is located in a cell, identify the two types of molecules that make up the rungs of a DNA molecule and identify the two types of Purine and Pyrimidine molecules
Curated OER
Reaching Into Your Genes
Students interact with a video to explore the basis for the science of chromosomes. They perform a chromosomal analysis called a karyotype and explore how seemingly minute errors in chromosomes can lead to devastating illnesses.
Curated OER
The Mad Pursuit Search for the Structure of DNA
Students complete a variety of activities as they study the historical story of Rosalind Franklin not receiving credit for her contributions in discovering the structure of DNA.
Curated OER
DNA Extraction From Onion
Students extract DNA from an onion using household equipment and supplies.
Curated OER
Diversity/Natural Selection
High schoolers examine mechanisms behind biological evolution and the theories that feed it, and are able to demonstrate their knowledge of these theories in a story.
Curated OER
Inheritance of Genetic Disorders
Students simulate the inheritance patterns of several different diseases caused by recessive genes. They identify and research five genetic disorders they would like to know more about and present their findings to the class.
Curated OER
DNA Fingerprints
Students interpret different DNA fingerprints, then do a jigsaw activity to explore other uses of DNA forensics. They listen to a radio program about using DNA as evidence and discuss the limitations of and problems with DNA testing.
Curated OER
Molecular Evidence for Evolutionary Relationships
Students compare the amino acid sequences in cytochrome-c for a variety of organisms and use this information to infer evolutionary relationships. They investigate the role of homeobox genes and what this indicates about the evolution of...
Curated OER
The Structure of DNA
Learners describe the structure of the double helix, explain how DNA copies itself, and recognize that the sequence of DNA is what makes each individual unique.
Curated OER
And the Verdict Is...
Young scholars identify the unique pattern DNA forms in each individual, and how that pattern can be used to identify criminals. They have the opportunity to simulate the process of matching DNA samples to those taken at a crime scene.
Curated OER
Cracking the Genetic Code
Students investigate different purposes for manipulating DNA. After reviewing the structure and functions of DNA, students explore topics related to the use or manipulation of DNA and the potential benefits and problems, later making a...
Curated OER
Get a Life!
Students read a New York Times article associated with the issue of the decoding for genomes, the creation of life in scientific laboratories and various genetic engineering topics. They present speeches of the pro's and con's of these...
Curated OER
lambda DNA Fingerprinting Simulation
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.
Curated OER
The Gift That Keeps on Giving
Students reflect on the role of DNA in society since its discovery in 1953 by creating works of art and poetry that metaphorically illustrate the importance, influence and concerns of DNA research.
Curated OER
DNA Fingerprinting for High School Biology
Young scholars work with tools and techniques used in genetic engineering. They dissect a sample into fragments of DNA using restriction enzymes, sometimes called "molecular scissors". They sort these fragments, measure and analyze them...
Curated OER
Games and Activities to Teach Molecular Genetics
Students demonstrate a working knowledge of cell interactions such as DNA replication, protein synthesis (transcription and translation), through active participation in a cooperative group.
Curated OER
Investigating DNA
Students engage in a variety of activities designed to facilitate the understanding of DNA. Activities include preparing human chromosome spreads, separating a mixture of dyes using gel electrophoresis and extracting DNA from onion cells,
Curated OER
Forensic Files
Students create a model of DNA and relate it to the differences between individual people in their nitrogen base sequences. They analyze a crime scenario in which they perform several different types of tests.
Curated OER
RNA
Learners explain how cells reproduce. In this biology instructional activity, students transcribe and translate a gene. They discuss and compare their answers in class.
Curated OER
DNA Technology
Students prepare PowerPoint presentation on DNA and cells. For this biology lesson, students create a storyboard of their presentation. They share the finished project in class.
Curated OER
DNA Technology
Pupils summarize their classmates' presentation in class. In this biology lesson, students create a graphic organizer based on concepts presented. They discuss and share their organizer.
Curated OER
Lesson 16: DNA Technology
Students research different areas of biotechnology. In this biology lesson, students create a presentation about their research. They debate the topic presented and share their views on the subject.
Curated OER
Lesson 5: Untangling DNA
Students extract DNA from split peas. In this biology lesson, students research how chromatin form into chromosomes. They draw the stages and present their work in class.
