Pupils explore Punnett squares and illustrate specific genotypic and phenotypic genetic outcomes. After a class discussion, students predict the probability of a specific trait being passed on by using Punnett squares. They reveal the...

Students build chromosome models using popsicle sticks. In this biology lesson, students simulate the Law of Independent Assortment. They use Punnett squares to predict the resulting genotype and phenotype.

Students explore the field of genetics. Through a graphing activity, students assess four common traits. They complete a Meiosis I and II charts which represent possible gametes for an individual. Students discuss phenotype and...

High schoolers differentiate phenotypes and genotypes. In this genetics lesson, students complete the punnett square. They design their own baby by choosing the phenotype they want.

Learners analyze different types of hemoglobin. They use the technique of agarose gel electrophoresis to separate human hemoglobin molecules according to their electrical charge, size, and/or shape. Students relate the migration of...

Students learn that genetic differences exist in all of us. That diversity is what makes us unique as individuals. Phenotypes are the physical characteristics that we develop from our genotype (our genetic makeup). Both the environment...

Students explore the field of genetics. They examine four basic traits. Students demonstrate their knowledge of phenotype and genotype by charting their personal traits. Students compelte a Meiosis chart. From the chart results,...

Trace simple genetic patterns of inheritance through a small population. Your students create a family pedigree that traces a genetic condition through several generations.

Three autosomal pedigrees are printed on this assignment. Biology scholars read them and determine the phenotypes for several individuals and find which ones inherit different genetic disorders. This fundamental skill can be reinforced...

Become familiar with the basic concepts of inheritance. Your junior high students work through mulitple examples of crosses and calculate probabilities of trait occurance. The explain the concept that each parent contributes one half of...

Students grow E. coli strain HB101, which contains the plasmid pUCD607 with the bioluminescence (Lux+) gene. The plasmid containing the Lux+ gene is isolated from the E. coli, then characterized by restriction analysis.

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...

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...

Genetic variation shows the health of a population, yet cheetahs show very little variation over that last 10,000 years. Scholars learn the importance of genetic variation in populations after viewing an informative presentation. It...

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...

The Hardy-Weinberg principle is the focus of this concise slideshow.  Some vocabulary definitions are given on the first 2 slides, and the rest are given over to examples of the Hardy-Weinberg theorem. Calculations of the H-W...

The five agents of evolutionary change are reviewed in this slideshow. Definitions of common terms involved with populations and equilibrium are given, and there are some presentations of Hardy Weinberg equations for common examples of...

Looking for a quick, hands-on activity to teach young scientists about Punnett squares through monohybrid crosses? then check out this one.

How and why do populations change over time? AP biology aces explore this question by completing this assignment. They write the answers to 21 questions regarding population genetics, stability, genetic drift, polymorphism, and...

Parts of the cell as well as genetic material begin this presentation.  As the slides continue, there are explanations of the main terms used in genetics.  The structure of genetic material, chromosomes, and replication are...

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...

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...

Use food coloring in electrophoresis. The last segment in a four-part series mimics DNA fingerprinting by using chromatography. Teams conduct chromatography on food coloring to find colors that use similar pigmentation in their makeup.

What does your class know about GMOs? Are they savvy to selective breeding? Challenge young minds to engineer the greatest crop of all time using a hands-on genetics unit. Learners discover the good and bad details of selective breeding,...
