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...

How did scientists determine the cause of illness before technology? Science scholars play the role of medical researcher in an engaging guided inquiry activity. Using observations, technical reading, and Punnett squares, learners...

Can your class solve the Mystery of the Crooked Cell? Junior geneticists collaborate to learn about sickle cell anemia in a fascinating lesson plan. The included materials help them to examine the genetic factors behind the disease...

How would you feel if you made a huge scientific discovery, published it everywhere, and shared it with every scientist, only to have it ignored for 35 years because no one understood your genius? Unfortunately, Gregor Mendel died before...

Show learners how to apply genotypes of parents to a Punnett square to determine potential genotypes and phenotypes of offspring with a video that explores monohybrid crosses and then complete a dihybrid cross as well. 

The peppered moth is featured in a video about natural selection. The narrator tells the story of Darwin's theory and then moves on to the principles behind natural selection and the different ways it works. Concepts covered include...

Animal reproduction in sheep and cattle is explored with the help of Punnet squares. Scholars employ tools using probability to conclude the color of wool a sheep's offspring will have. Acting as animal geneticists, pupils then take...

Believe it or not, birds are dinosaurs! Scholars view evidence that connects birds to dinosaurs in a video lesson. The narrator outlines factors that prove birds are descendants of dinosaurs.

We've heard about pygmy pigs—why not pygmy mammoths? Fossil evidence proves their existence, but the dilemma is figuring out where they lived. A video describes different theories on their evolution and migration.

You may struggle to find similarities between humans and many of our ancestors. Fossil evidence finds more and more signs of similarities between humans and many other species. A lesson outlines the fossil evidence and the questions...

Some traits only exist in males and some only in females. Pupils learn how the location of genes on sex chromosomes determines them using an interactive lesson. An animation illustrates how scientists know this to be true and shows how...

Rules are not meant to be broken in genetics. Scholars learn to build Punnett squares to track the inheritance of dominant and recessive traits in an interactive animation activity. Online questions help individuals reflect on their...

Dominate a lesson on genetic traits. Young scholars learn about the difference between dominant and recessive traits with an interactive lesson. An animation demonstrates Mendel's work on the inheritance of traits, and interactive...

Yellow and blue make green—unless you're studying the inheritance of genetic traits. An interactive lesson explains the difference between blended traits and pure traits and gives examples of their occurrence. The resource includes a...

Mendel was the first to look at individual traits within a species. Step in his shoes as an interactive lesson takes users through his journey. An animation describes the design of his experiments and how he isolated individual traits to...

Gregor Mendel's work revolutionized agriculture from an art to a science. Explore Mendel's work with an interactive lesson that includes animations, video, and practice problems. The instruction describes the early discoveries that...

Where are they now? Apes are humans' closest evolutionary ancestor, yet they only live in small areas in Africa and Asia. Learn how their geography changes with evolution in a video lesson from the PBS Eon series. 

You think mice can be a nuisance, wait until you meet the capybara! An installment of the PBS Eons series traces the genetic background of a large group of rodents known as the Caviomorpha. Fossil evidence indicates they originate in...
