Students model traits on genes using colored paper and tongue depressors to represent chromosomes. In this heredity lesson plan, students use their "chromosome sticks" to understand chromosome pairs, genes, dominant traits, recessive...

Young scholars receive instruction on dominant/recessive traits, access World-Wide Search for the Dominant Trait and download information on which traits to assess. They collect data on at least 20 people and prepare a data chart.

Six genetics problems are to be solved by junior geneticists. Empty Punnett squares are provided for them to plant the parents' alleles and determine the genotype, phenotype, and frequency of offspring. All of the problems involve actual...

Can scientists really predict genetic outcomes or are they simply making a lucky guess? Scholars first learn about Gregor Mendel and how to make Punnett squares. Then they extract DNA from a strawberry in a lab with included conclusion...

Did she cheat on her husband? Did the hospital switch the babies? Should they have children? As much as this sounds like the plot for a soap opera, all of these questions fit into a single lesson on genetics. Scholars read about three...

Young scholars describe and apply the Mendellian principles of genetics, focusing predominantly on dominant and recessive genes. They demonstrate how two parents contribute genes and how those genes appear in their offspring. They...

In this biology worksheet, 9th graders create a Punnett square to show the possible offspring of a carrier female and a normal male for color blindness. Then they draw a pedigree for the family and indicate whether the daughter is...

Ninth graders review the terms "aneuploidy," "fetus," and "karyotype" in this vocabulary instructional activity, which includes three multiple choice questions about each term. This activity could be expanded into a more developed...

Students explore human behavior by participating in a class science game. In this human characteristics lesson, students identify different human traits that are passed down by each generation and the purpose each of them have. Students...

Four two-generation pedigrees are presented in this genetics worksheet. For each, five questions are asked: Is the trait autosomal recessive, autosomal dominant, x-linked recessive, x-linked dominant, or y-linked dominant? Whenever...

In this paper pets genetics instructional activity, students are given 4 genetic traits found in a particular species (paper pet). Students are given the genotypes of the parents of the paper pets and they perform genetic crosses using...

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...

Students explore heredity. In this science lesson plan, students examine what heredity is, distinguish the difference between the dominant and recessive genes, explain the difference between phenotype and genotype, and predict the...

In this biology worksheet, 9th graders describe how two alleles can produce three phenotypes. Then they create a Punnett square showing the possible offspring of red and white cattle. Students also determine the genotypes and phenotype...

Students explore the mode of inheritance of chromosomes. Given a scenario, students use the Human Genome sheet to determine inherited chromosomes. They illustrate the difference between genotype and phenotype. Students develop a model...

Sixth graders consider heredity. In this science lesson plan, 6th graders gain an understanding of certain physical traits are inherited from their parents through the genes.

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...

Investigate the Hardy-Weinberg Principle to explain genetic equilibrium. The 10th lesson plan of a series of 12 is a laboratory exploration of genetic equilibrium. Your classes use a mixture of beans to model allele and genotype...

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...

Students observe and record observations of whether a person is a taster or nontaster. They test selected individuals from their families and peer groups and chart all findings to determine which trait (e.g. taster or non-taster) is...

Study, manipulate, and research genetic traits. Discuss how genetic traits are passed from one generation to another. Classmates explore how they look like their parents and debate whether or not they can do anything about it? They...

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 explore how genetic information is passed down from parent to offspring. Because of this, they examine how this causes the variation in each species.

How often do you find a science worksheet that comes with separate teacher's instructions? Here is one of those rare instances. Goals and objectives, materials, and evaluation guidelines precede the actual assignment. Biology leaners...
