Find Punnett Square educational ideas and activities
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 complete Punnett squares, identify genotype and phenotype, and calculate ratios.
What a fun way to explore Mendelian Genetics! Using a computer connected to the Internet, beginning biologists construct and use Punnett squares of monohybrid crosses to explain how genetic traits are passed to offspring. Other websites used in the activity include a summary, a tutorial, and the interactive opportunity. Get your biology class into the computer lab for a different way of working on Punnett Squares!
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 determine the probability of an offspring having certain traits. To end the lesson, they complete a problem to determine the correct combination of genes related to hairless dogs.
A two-page worksheet provides seven Punnett squares for practice in determining genotypes and phenotypes. Each is an example of incomplete dominance or codominance. After your bright biologists have mastered Punnett squares, this will take them to the next step. Assign it as homework or use it as an assessment after some time have been invested in these genetics concepts.
Imagine a pair of dragons that produce offspring and determine the percentage of the hatchlings have wings and large antlers. This fantastic activity draws genetics learners in, introduces them to alleles, meiosis, phenotypes, genotypes, and teaches them how to use Punnett squares. The exercises also illustrate the law of independent assortment and linked genes. The handout is ten pages long and will take days to work through, but it will definitely keep learners engaged!
Dive down to Bikini Bottom for a fantastic lesson on heredity! High school scientists make phenotype predictions for various characters based on given dominant and recessive traits. Use the PowerPoint here to review this concept before splitting learners into small groups. They experiment with probability using a coin toss, organizing findings on a worksheet (linked). Next, they conduct a virtual lab to practice completing Punnett Squares and explore another interactive site with a quiz. Synthesize their skills with two Sponge Bob worksheets which, after completed by all groups, can be presented in a jigsaw fashion. Use the final quiz here as assessment.
Hilarious! Use the characters from SpongeBob Square Pants to practice solving genetics problems! Yellow sponge body color is dominant to blue. Square body shape is dominant to round body shape. Did someone switch Mr. Krab's baby with one that has short eyeballs? The stories are fictitious, but the concepts are still sound. This worksheet, which comes with an answer key, will make solving Punnett Squares much less square!
Students review genotypes and phenotypes by taking a quiz. They calculate the probability of hail. After discussing and observing Mendel's Punnett Squares, students calculate probability problems and then use Punnett squares to solve the problems and identify the genotypes and phenotypes.
Geneticists manipulate Punnett squares to determine the patterns of dominant and recessive gene influence on first and second generations of humans and plants. The technology-based lesson plan employs a variety of media for exploring heredity and is ideal for the middle school life science classroom.
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 determine the genotypes and then solve a Punnett square for their cross. Once they predict the genotype and phenotype of the offspring, they open the egg. You will have pre-planted colored candies within the eggs according to a corresponding phenotype. This is a clever instructional activity for making the passing of alleles more visual.
Now that Nemo has been found, it's time to find his phenotype. Using basic genetics, middle or high schoolers determine how to break down traits in an engaging worksheet that allows kids to show what they know about Punnett squares, genotypes, and phenotypes. To modify this, your young geneticists could work with partners to complete the handout.
Seventh graders describe how the traits of an organism are passed from generation to generation. They distinguish between asexual and sexul reproduction. Students identify traits through genes and those resulting from interactions with the environment. They use simple laws of probability to predict patterns of herdity with the use of Punnett squares.
"Genetics Review Sheet" is exactly that: a genetics review sheet. Assign this as homework so that your biology learners can practice solving Punnett squares and brush up on genetics vocabulary. The third page of this resource appears to be a reading guide for a specific textbook, but the fill-in-the-blank style questions should be answerable by any student of genetics.
