Consider the riddle of dragon genetics. Young scientists simulate being dragon parents and determining which traits their child will have. Then they learn of a new relative and must determine how they are related using probability and...

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

Ever been told you have your father's eyes? How did it happen? Young biologists get a hands-on experience in meiotic gene expression with a fun pairs-based activity. Participants use pipe cleaner chromosomes with trait beads to make...

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...

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...

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...

Take your advanced biology learners across the great divide: where cells divide, that is! Although it was created as a chapter reading guide, having your class complete this worksheet is not only appropriate, but also highly valuable in...

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...

Investigate the ins and outs of cell division with this comprehensive set of activities. Detailed instructions for six different activities and your choice of eight different creative assessments can be found within this resource. By...

Discuss an article about families affected by genetic disorders and their decisions about whether or not to evaluate their own genetic information. Investigate four different inherited disorders. Participate in a probability exercise....

Fill- in-the-blank, labeling, and short answer questions make up this well-written cell division worksheet. Neat diagrams of chromosomes and dividing cells are included. Junior biologists show what they know about reproduction, meiosis,...

See how the strands of DNA separate and become a template for a replica to be incorporated in a new cell! The microbiology and biochemistry of the process is detailed. This lecture refers to the concepts of transcription and translation...

Do you know how many chromosomes humans have? Do you know how many of those chromosomes we share with the chimpanzee? A perfect introduction to DNA for your middle schoolers, this video uses a ton of visuals to clearly illustrate the...

Why do people age? Scholars explore the concept of telomeres and why they are so important in cells. They learn about the role of telomerase and why it is active in some cells—but not in others. The video also explains why some organisms...

Have you ever wondered why calico cats have such a colorful coat? The process of X inactivation is an interesting phenomenon in females that drives the physical appearance of individuals. Viewers of an intriguing video connect knowledge...

Human traits trace back to simpler species—such as chickens, for example. Using the human genomes, scientists connect these traits to their ancestral origins. A video presentation highlights the structure of human DNA and makes a...

There are reasons elderly people are more susceptible to diseases. A video lesson instructor discusses the changes cells endure over someone's lifespan and how that affects the likelihood of contracting a disease.

More than 90 percent of humans' DNA doesn't code for anything! Scholars watch a presentation as they answer questions relating to gene mutations. They read details, watch videos, and view animations supporting the concepts. The questions...

Today researchers identify a gene suspected of causing a genetic disease in a matter of days rather than years, thanks to the Human Genome Project. Young scientists learn about the Human Genome Project and the scientists who designed the...

Some people have a natural ability to jump, but did you know DNA also naturally jumps? Learn about the fun habit by looking at the research of a pioneering female scientist. Barbara McClintock fought prejudice and surpassed her mentors...

Roy John Britten easily earned a PhD in nuclear physics—but he found painting with water colors too difficult. Young scientists learn about Britten's life, career, and research with an online interactive. They read a biography, view...

Chromosomes contain keys to history including links from royalty to Neanderthals. Young scientists learn about Ivan Wallin's research into chromosomes with an animation and videos. Then, the concept connects to mysteries related to...

Some genes link to others that have implications for inheritance. A set of resources lead pupils through the history of this discovery. They explain how chromosomes recombine and which parts are more susceptible to this linkage....
