Show your class why restrictions aren't always a bad thing. In the third segment of a four-part series, the instructor develops the idea of restriction enzymes. Pupils learn how scientists use restriction enzymes in DNA analysis and DNA...

Civil rights meets biotechnology in a instructional activity that scrutinizes the collection of DNA of citizens who have been arrested, but not yet convicted of a crime. Real-life cases are examined in which the DNA of a relative was...

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Enzymes proofread DNA, reducing the error rate to one in one billion base pairs. Learn about the important process and so much more with the help of a presentation. It opens with the history of DNA and the major scientific contributions...

Where is a geneticist's favorite place to swim? A gene pool. Young geneticists complete hands-on activities, experiments, and real-world problem solving throughout the unit. With extra focus on dominant and recessive genes, Punnett...

Around six percent of babies are born with serious genetic disorders. Young scientists learn more about what causes these disorders and the effect they have. They begin with a case study of cystic fibrosis before expanding to research...

Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create matching strands...

Match up the DNA code. Pupils read the website from the American Museum of Natural History about how DNA can determine whether a skin is from a particular type of reptile. Using the same technique, learners match up products with the...

A pinch of adenine, a dash of thymine and ta-da, you have life! Well, it's not quite that simple, but through this series of activities and experiments young scientists learn about the structure of DNA and how it contains the recipe...

While much of prehistory is cloaked in mystery, ancient ancestors left evidence in DNA, languages, and materials from their time. Using photographs of items such as cave paintings and ancient tools, as well as maps of linguistic patterns...

Ever wonder how they solve those mysterious murders in TV crime dramas? The second of four units in a Biotechnology series introduces scholars to the many methods of DNA analysis. Pupils create and run their own gel electrophoresis...

Did you know that all life on Earth has DNA? Explore the importance of the molecule by learning about its structure. The unique DNA shape, bases, and bonds allow the incredible diversity seen all over the world.

Unravel the complexities of DNA research. Analyzing DNA data can be a daunting, time-consuming task; however, as the lesson explains, an interactive importance of the research outweighs its complexities. The presentation breaks down the...

One of the first models of DNA appeared to be a triple helix. Young scientists learn about the many scientists who worked to find the shape of DNA. They observe multiple models, tests, and experiments to understand the conclusions. An...

Engage learners with an intriguing presentation on DNA and its role in organisms. Individuals see its structure, what genes are, how the code works, and then explore DNA replication. For advanced classes, the presentation introduces...

How closely are animals related? Check their phylogenetic trees! The use of DNA sequencing altered our understanding of these relationships. Individuals explore and gain a better understanding of how scientists sort, align, and determine...

Virochips detect and identify viruses at a higher rate than other tests. Show young scientists how Virochips work to identify existing viruses. They analyze results demonstrating mutations or the evolution of viruses and view videos...

Unravel the DNA molecule in just over a minute! Future geneticists listen and watch a video exploring DNA's structure, function, and the interaction of the genes and proteins that decode and interpret the complex molecule. Scholars...

COVID-19 = CO (corona) + VI (virus) + D (disease) =19 (the year the disease first appeared) NOVEL (unknown to scientists and never before infected human patients). A colorful nine-slide presentation details what is currently known about...

One of the first biotechnology breakthroughs occurred in 1982 with the creation of synthetic insulin. Young scientists learn about DNA technology with a presentation and accompanying worksheet. It focuses on DNA extraction and...

DNA is like the fingerprint of genetics. A quick lesson introduces the topic of DNA sequences with a mystery about an endangered species. The lesson shows how DNA extraction, replication, and sequencing often provide undeniable evidence...

A mammalogist, ornithologist, ichthyologist, and a conservation geneticist share their work and their hopes that their research will help protect and save endangered species and their habitats.

Let's get a closer look at DNA and other molecular structures. The first lesson in the series of four introduces a variety of imagining techniques that engineers and scientists use to visualize molecular structures. The resource presents...
