Dare to be Punnett Square

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

How often do you find a science activity 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...

Factoring is one of the first places in math that a young algebrist runs into multiple ways to work a problem. For the more concrete learner who needs a visual structure for problem solving, this presentation of factoring using a Punnett...

What type of pig is always smiling? A grinny pig! The video is an excellent introduction to monohybrid crosses and simple Punnett Squares. It includes explanations of dominant versus recessive and genotype versus phenotype. 

"The neat thing about completing the square is that it will always work," Sal explains, "no matter how crazy the problem is." A basic overview of how to complete the square, this video provides a good background for both beginning and...

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,...

It's hip to be square! The first of a two-lesson series combines computer simulation and physical manipulation to illustrate perfect squares. Partners use geoboards to measure the length of sides, perimeter, and area of squares....
