Description |
| Genetics and Proportions Design Challenge | Students will explore principles of heredity through an activity where they design a themed Potato Head toy set. |
| 3D Printing: Designing Robots Using Heredity and Probability | This lesson explores the importance of Punnett squares in determining genetic characteristics. It uses a 3D printer to demonstrate these characteristics. |
| Smith Valley Farms Horse Pedigrees | The owner of newly opened Smith Valley Farms is looking to breed the next generation of top race horses. In this MEA, students will study race horse pedigrees as well as horse racing data to determine which is the best stallion to breed with a filly. Students will have to read a horse pedigree, calculate percentages based on a data table, and complete Punnett squares to determine genetic probability.
Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom. |
| Genetics Has Gone to the Dogs! | This lesson uses pooches to teach about pedigrees and the impact of artificial selection on individuals and populations as well as to drive home math concepts already discussed in lessons on Punnet squares. |
| Monster Mash-Up of Genetics | Students will participate in determining traits of a monster by throwing a die. Students will develop an understanding of how genetics play a role in determining the phenotype of an individual. |
| It's Not Easy Being Blue | After students have an understanding of Punnett squares and their purpose, students will then be introduced to pedigrees. Students will be shown the purpose of pedigrees, how to read them, and how to create one. |
| Genetics can be a Monster! | In this lesson, students will use Punnett squares to calculate the probabilities of different genotypes and phenotypes produced by genetic crosses. |
| Hair or No Hair- Please tell me Punnett Square | This lesson is designed to teach students how to read and interpret Punnett square with the final goal of them creating their own squares. The students will be able to determine possible genotypes and phenotypes of offspring based parent alleles. |
| Manipulating Punnett Squares | Students will learn how to draw, complete, interpret, calculate the probabilities, and figure ratios for single trait crosses with complete dominance interaction. |
| Genetics: Smile for the Camera, Baby! | The words "create a baby" will grab the attention of any student. After studying the probabilities for genotype and phenotype using Punnett squares, this is an activity that will unify all previous tasks. The activity asks students to illustrate a baby using prior knowledge of vocabulary such as allele, trait, phenotype, genotype, dominant, and recessive.
The goal of this lesson is to take the pieces and parts of the "genetic language" that has been taught using Punnett Squares and pull everything together to show that "genetic material from mom and dad make me." The creation of a baby from single inheritance traits will reinforce why we study probability of what offspring will look like, what an allele is, and what the difference between phenotype and genotype are.
Note that incomplete dominance and polygenic traits are represented by single gene traits only for the purposes of this lesson. |
| Build-A-Baby | Students will examine Gregor Mendel's laws of genetics in this lesson. Students will first explore the range of variation in human physical traits and discuss where this variation comes from. They will be then paired into groups and given the role of genetic counselors that are trying to predict the traits of offspring using traits of their parents. A toss of a coin will represent alleles for various characteristics. Students will combine dominant and recessive traits to determine the phenotype and genotype of their genetic babies. Their predicted baby will be displayed for peers to view. As an extension to this activity, the students can learn that through gene technology, parents may soon have more choices available to them: hair color, physical size, intelligence. Students canl research and evaluate how can science answer new and ethical questions. |
| Getting the Most Genetics out of SpongeBob | Students work collaboratively to explore genetics with SpongeBob and the Bikini Bottoms gang! The learners will take pre/post quizzes, watch a short video clip, complete a worksheet cooperatively within small groups, and rate their understanding using the learning scale included with the lesson. The activities within this lesson is best implemented towards the end of a unit on heredity and genetics. |
| Genotype, Phenotype, Schmenotype? | The lesson provides a hands-on activity for students to distinguish between genotype and phenotype. |
| Discovering Genotype and Phenotype | This lesson primarily addresses students discovering the concept of dominant and recessive alleles by examining how genotype determines phenotype through a structured inquiry. Punnett squares are also introduced as an extension of the primary activity. |
| Independent Compound Probability | During this lesson, students will use Punnett Squares to determine the probability of an offspring's characteristics. |
| Grandma's Mysterious Plants | This lesson, which follows the Argument Driven Inquiry model of instruction, asks students to use a Pedigree and Punnett Squares to explain Grandma's mysterious plants. Given physical traits in a small population of plants, students determine which gene is dominant and if a specific group of plants is homozygous or heterozygous. |
| Computer Simulated Experiments in Genetics | A computer simulation package called "Star Genetics" is used to generate progeny for one or two additional generations. The distribution of the phenotypes of the progeny provide data from which the parental genotypes can be inferred. The number of progeny can be chosen by the student in order to increase the student's confidence in the inference. |
| Super Hero Genetics - Bioengineering & Heredity | In this Model-Eliciting Activity (MEA), students must help geneticists develop a new breed of scientific explorer. Using knowledge of genetics, genotypes, and phenotypes, students must select a combination of alleles that could create people better adapted for exploring dangerous areas and other worlds. Then, students must choose which genetic alterations to apply to themselves!
Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought processes. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

| I Have a Pedigree too, Prince Charles! | In this lesson students will investigate pedigrees and culminate in an activity where students create their own or imaginary pedigree. |
| Where Do Our Looks Come From? | This is a lesson on genes, alleles and chromosomes. This lesson will teach dominant and recessive genes. |
| Probabilities and Punnett Squares | Students simulate the process of meiosis for an alien society. The students choose physical characteristics for hair, nose and eyes corresponding to genes and then generate two alien babies. Then pictures of the parents and babies are drawn, with similarities and differences noted and explained. |
| Genotype and Phenotype Probabilites With Punnet Squares and Pedigrees | Lesson to help students understand how to predict genotype and phenotype probabilities using Punnet Squares and pedigrees. |
| Genotype and Phenotype Activity | This is a hands-on activity that will help students distinguish between genotype and phenotype. |
| Heredity Mix 'n Match | Students randomly select jelly beans (or other candy) 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 those corresponding to their own genotypes. The new pairs are placed on toothpicks to represent the chromosomes of the couple's offspring. Finally, students compare genotypes and phenotypes of parents and offspring for all the "couples" in the class. In particular, they look to see if there are cases where parents and offspring share the exact same genotype and/or phenotype, and consider how the results would differ if they repeated the simulation using more than four traits. |
