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...

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...

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...

Welcome to the complex biological story that is our life. Great visual imagery zooms in on the dissection of a DNA double helix in our body. What happens with RNA? Where do amino acids come in? This resource explores our inner workings...

What exactly is DNA? How is it formed? What is its purpose? Mr. Anderson explains the basics of DNA using visual information, clear lecture style descriptions, and his own unique flare. Tip: After lecture send home this video to provide...

These aren't the type of jeans you can buy at a local store! Help your class understand what determines if you're a girl or a boy. Show this cartoon representation of how a male and a female's chromosomes shuffle, divide, and recombine...

If humans share over 99% of the same chromosomes, how are we different? There are 10 million SNPs in the human genome, accounting for most of our genetic differences. Watch this short clip to introduce your learners to SNPs, or single...

Take a close up look at the replication of DNA and protein synthesis with this animated clip. The process is described in detail for your biologists. Utilize technology in order to see the inner workings of the cell.

Part five of the 13-part series begins with a refutable argument stating that genetically, the ancient people of Australia were populated by the first African ancestors. Spencer Wells travels to India to find the link that bridges...

Biotech engineers discover that changes in the DNA code for cell wall formation can help create crops better suited for biofuel production. They extract DNA from wheat germ. They decode paper strips with codes and relate the activity to...

"More Mutations" has more quality packed into one worksheet than most. Junior geneticists are queried about different types of mutations, mutagens, changes in DNA sequences, and more. Space is provided for them to write their answers...

This is a polished presentation of the nucleic acids. It is unique in that it examines both the genetic material and the energy molecules. Usually these are addressed separately even though they are both nucleic acids. This approach is...

Translation, the second half of the protein synthesis process, is reviewed in this nifty handout. Young DNA experts explain what codons are and how they work. They label diagrams and differentiate between introns and exons. The worksheet...

Junior geneticists tally eye color and height in their lab groups. They examine certain traits in soybean and corn seedlings. For each activity, they gather data and learn about continuous and discontinuous genetic variation. In another...

Six different chromosome activites introduce biology aces to heredity, chromosomal abnormalities, sex-linked traits, and the human genome. The hands-on activites are fairly simple for the teacher to prepare and will prove to be both...

High school learners read and discuss an article about genetic ancestry and genetic ancestry testing. They complete a paper and pencil activity that mimics the function of a DNA microarray and consider the ethics of genetic testing in...

A concise and instructive presentation on nucleic acids will be a valuable teaching tool in your chemistry or biology classes. Beautiful diagrams clarify the structure of nucleotides in DNA and RNA and the double helix arrangement of the...

High school science classes will find this video intriguing. Viruses contain genetic information, but there are strong arguments for whether viruses are living or not. Replication versus metabolism and some details about the immune...

Use this resource to have your class learn about the cell. This resource walks learners through the construction of a model of a cell. This project is completed in a cooperative learning group, and  reinforces the higher-order thinking...

Students use microscopes to study live fish embryos and animated diagrams of cell division on the Internet. They see that scientists rely on technology to enhance the gathering and manipulation of data. They create web pages on cloning.

With flu a topic on everyone's minds, this PowerPoint on viruses and bacteria is sure to pique students' interest. This presentation provides a comprehensive overview of viruses, bacteria and vaccines in an easy to understand format. It...

Explaining exactly how DNA works to provide genetic information is a complex topic, but it is presented in a clear and engaging way through a five-minute video. Have learners try to explain how DNA works before watching the video, then...

Stop animation helps Jeremy describe the components of the Double Helix structure of DNA. This is actually a very informative clip which will make explaining the nature of DNA easy to understand.

Watch as an animated cell goes through the process of mitosis as DNA coils and bunches into chromosomes. Once the nuclear membranes dissolve, spindles pull chromatids to opposite sides and stretch the cell. The video ends as mitosis...
