Dare to be Punnett Square

What do geometric squares have to do with quadratic equations? A instructional activity on solving quadratic equations by completing the square teaches middle and high schoolers how to use algebra tiles to create squares. They then use...

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...

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

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...

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...

Whatever you do in life, always give 100 percent—unless you are donating blood. A video explains how to solve Punnett squares with multiple alleles, in this case blood types. It includes what happens if the wrong type is added, which...

Introduce young biologists to monohybrid crosses and simple Punnett Squares. It includes explanations of dominant versus recessive and genotype versus phenotype by exploring different genetic combinations of guinea pigs. 

Until the 1960s, the life expectancy of a hemophiliac was only 11 years. An informative video explains how to solve a Punnett square when there is a sex-linked trait — in this case hemophilia. It includes a discussion of the xy...

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...

A brief animation introduces heredity to your beginning biologists. They will meet Gregor Mendel's green and yellow peas, dominant and recessive traits, homozygous and heterozygous alleles, and Punnett squares. In this cartoon animation,...
