RNA Was the First Genetic Molecule
Can organic molecules come from a pre-biotic environment? Stanley Lloyd Miller proved it is possible when exactly the right conditions exist. Learn about his experiment and the other experiments later building off of it that changed the...

Mendelian Genetics
How did Mendel know which pea plants would demonstrate certain characteristics? Pupils explore the answer this question, among others, as they complete Punnet squares, research dominant and recessive traits, and explore hereditary...
Curated OER
Patterns of Heredity
Students describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then...
Curated OER
Mendelian and Non-Mendelian Heredity
Tenth graders discuss their physical features, and why they look the way they do. They listen as the teacher discusses DNA, alleles, and dominant or recessive genes. Students perform an experiment with different colored markers...

Genetics and Heredity: The Next Generation
Tenth graders work in teams to order events of DNA transcription and translation protein synthesis. In the second lesson, they put the steps of mitosis and meiosis in order using a concept map poster. They use modeling clay to create...

Heredity Mix 'n Match
Students randomly select jelly beans that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from...

Genetic Testing: Modern-Day Eugenics?
Students trace the history of the development of Eugenics. In this social studies lesson, students read and analyze a real life case. They write a paper about what they read.

Chromosomes Carry Genes
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...

Heredity Worksheet #3
In this heredity learning exercise, students complete two monohybrid crosses and predict the expected outcome of genotypes and phenotypes. They answer five questions about each genetic cross.
Curated OER
Heredity Worksheet: Dihybrid Cross
For this genetics worksheet, learners use a Punnett square to determine the genotypes and phenotypes of the offspring of a dihybrid cross. Then students complete 10 fill in the blank questions.

Got Lactase? The Co-Evolution of Genes and Culture
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...

Cell Wall Recipe: A Lesson on Biofuels
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...

DNA from the Beginning Study Guide
Students complete a study guide using a website which is an animated primer on DNA, genes, and heredity. The Web site is organized around key concepts. The web links and study guide are included.

Twins!
Young scholars study genetics and how twins can be identical. In this genetics lesson students research twins and how heredity, environment and personality play a part.
Curated OER
An Inventory of My Traits
In this biology activity, students identify and describe a number of easily observable genetic traits and compare the traits they have with other students. Then they identify and describe that some traits are common while others are not...
Curated OER
Tamar Burris
Students explore genetics. In this life cycle instructional activity, students consider the meaning of "genes" and "heredity" as they watch a video about the topics. Students then research their own genetic make-up as they interview...
Curated OER
The Cell
Students study the basic processes by which cells divide and transfer their genetic information. They recognize and distinguish possible inherited traits and through the discovery method of the facts and principles of inheritance. this...
Curated OER
Where Did That Curly Hair Come From?
Students pronounce (as best as they can) the scientific term used in explaining heredity. They study the meaning and/or significance of these genetic terms and use these words in sentences relating to the information taught in the unit.
Curated OER
Heredity Worksheet #2
In this genetics worksheet, students use a diagram showing the genetic offspring of plants with different types of seeds to answer 4 short answer questions. Then students determine the traits of offspring of different crosses in 1...

Designer Genes: One Size Fits All?
In this STEM group of 10 activities, lesson two focuses on the question, "Just because we can, should we?" when considering genetically engineered food. Classes hear a scenario and, as young scientists and geneticists, must determine if...

Where It Comes From: All About Heredity
Characteristics are not only inherited, but can be acquired through interactions with the environment.
Agriculture in the Classroom
Design 'Y'er Genes
How do changes in DNA affect an organism? Scholars explore chromosomes, genes, DNA, and mutations by modeling the DNA of a strawberry. They build a DNA model, then manipulate it to show how changing the genes transforms the strawberry...
Beyond Benign
Punnett Square Possibilities
Discover possible genetic outcomes through Punnett Squares. Learners continue studying genetic traits in the 10th lesson in the 17-part series. After determining the father of Sparky's kittens, scholars now attempt to predict the traits...

Paint's Family Tree
Students sort and classify the genetic traits of horses. In this heredity and genetics lesson, students read dialogue in a skit in which specific physical traits of several horses are described and a horse family tree is created....
