Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

Bring the excitement of genetics to scholars with a dynamic hands-on meiosis modeling experience. During the activity, biologists follow step-by-step procedures to build chromosomes, model independent assortment, learn about crossing...

Who's your Daddy ... and Mommy for that matter? Given a first-generation group of gummy bear offspring, young scientists must determine which bears are their parents. An activity learning exercise covers the differences in genotypes...

How do seeds get around? It's not like plants can control seed dispersal—or can they? Dig deeper into the amazing mechanisms of seed dispersal observed in tropical plants through interactives, a video, and plenty of hands-on data...

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...

Around half of the states in the US ban first cousin marriage, but does science support that ban? Scholars work through genetic analysis of the risks to understand if more states should ban the practice—or if some should remove it. They...

A diagram, data table, and reading passage top this resource. Through it, biology beginners are introduced to the concept of natural selection. They answer some questions and then participate in a simulation using fabric as a habitat and...

By observing photos of plankton at different life stages, students can obtain information that will allow them to construct evidence-based accounts of how parents and offspring don't always look alike.

This site includes a lesson plan designed to teach students how genetic traits are passed down from parents to offspring. Students will explore such concepts as random selection, chrosomes, genotypes and phenotypes using jelly beans and...

In this activity, you will use an alien model to demonstrate how genes or physical traits are passed on from parents to their offspring.

A simulation where students flip coins to mimic how parents pass genetic traits to their offspring through heredity. This activity also illustrates the difference between dominant and recessive genes, and how they interact with each...

First, students toss coins to determine what traits a set of mouse parents possess, such as fur color, body size, heat tolerance, and running speed. Next they use coin tossing to determine the traits a mouse pup born to these parents...

Based off of the hit television show NUMB3RS, this lesson shows students the scientific reasoning behind the societal taboo of incest. Students complete a Punnett square to determine the chances of an offspring inheriting two recessive...
