Explore the science behind Earth's amazing diversity of life with this lesson on genetics. Looking at specific traits in piebald deer, carnations, and roan cattle, young scientists use Punnett...

Where is a geneticist's favorite place to swim? A gene pool. Young geneticists complete hands-on activities, experiments, and real-world problem solving throughout the unit. With extra focus on dominant and recessive genes, Punnett...

Has your class ever been astounded by the complexity of DNA analysis? Have they ever asked why genetic engineering has become so important to our daily lives? Young scientists perform DNA extraction on strawberries and explore how the...

Using plastic Easter eggs to represent parent phenotypes, genetics enthusiasts simulate the passing of alleles. They record the phenotype of each half of the egg, one representing the mother's and one representing the father's. They...

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...

Genetic analysis has gone to the dogs! Learners use real DNA information collected from dog saliva to study the relationship between genotypes and phenotypes. They analyze alleles to determine correlations to coat color, length, and...

Eighth graders take a short quiz on genotypes and phenotypes. As a class, they are introduced to the concept of Punnett Squares and listen to a description of Gregor Mendel's pea experiment. In groups, they complete Punnett Squares to...

It has been decades since the discovery of DNA. Still, activities such building this DNA model allow blossoming scientists to better understand the components that form this overall structure. During this activity, they will also...

In a world of DNA testing popularity, understanding how to solve basic genetic problems allows scholars to better understand and interpret test results. They work through many different types of genetic problems using statistics, Punnett...

Young scholars investigate a rapid method to render the bacterium Escherichia coli "competent" to uptake plasmid DNA. They demonstrate the phenotypic changes associated with transformation. They perform a cell resuspension from the...

A handout on genetic inheritance begins with a reading on alleles and how they can result in albinism. Junior geneticists learn to complete Punnett squares and participate in a coin toss simulation of allele pairing. They also learn...

Have you ever wondered why you aren't taller or invisible? It all comes down to your dominant and recessive genes. Introduce your class members to genetics with a presentation that includes worksheets for young geneticists to...

What makes each one of us unique? Lead your class in this exciting and educational activity as you uncover traits that show how each individual is different from another. Pupils explore facts about DNA technology and predict the...

Need an a-maize-ing lesson to show your class how regulatory genes work? If you use the well-written resource, they'll be all ears! Biology scholars discover the gene responsible for the evolution of the modern-day corn plant through a...

Matching and fill-in-the-blank exercises give biology whizzes a chance to practice vocabulary associated with evolution. Terms to be reviewed focus on evidence for evolution, natural selection concepts, and some genetics words. You could...

After your biologists have learned about transcription, translation, and gene regulation, they work in a small group to create a poster of a system that serves as an analogy of the gene regulation process. They share their creations with...

Explore single-gene traits in humans. After viewing a video introducing genetic vocabulary, individuals identify their phenotype and possible genotypes of specific traits. They consider both dominant and recessive traits. This is the...

You may not know if that zebrafish in your fish tank is a model citizen—but it is definitely a model organism! What can we learn about ourselves from a tiny zebrafish? Discover more about the polygenic trait of skin color through a...

Students view a video on DNA. They discuss mitosis, meiosis and fertilization. They use strips of paper to simulate fertilization and analyze the genotype and phenotype of the combined chromosomes.

Freddy's Friendly Fruit Market is under attack by fruit flies, and it is up to your aspiring biologists to solve the crime! By reading and analyzing the phenotypes, detectives determine which fly is responsible. This memorable assignment...

High school learners identify chemical and structural properties of DNA and explain the differences between genotype and phenotype. They develop a scientific investigation to determine the ethnic heritage of a large group of people. 

In this science worksheet, students answer 15 questions about mitosis and meiosis. For example, "What is a major feature of prophase in mitosis?"

Does where we live influence how our bodies express genetic traits? Explore variation in human skin color with an activity that incorporate video and hands-on learning. Individuals model the relationship between phenotypes and genotypes,...

Everything is in the genes. Individuals observe 14 different traits of themselves. Using pipe cleaners and beads, the learners create models of a chromosome representing their traits. The class then compares and contrasts everyone's...
