So Whose Cow is in the Field?

Some say cooking is an art—and a science! Scholars scope out the savory subject of molecular gastronomy with a series of related activities. The teacher's guide contains printable worksheets and helpful tips for implementing the...

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

While a herd of cows are eating, they tend to all face the same direction. Viewers explore the world of animal behavior, looking at both morphology and physiology, with a video that focuses on the evolutionary history of learned...

Any pattern of inheritance that does not follow Mendel's laws uses non-Mendelian inheritance. The video explains this type of genetics with many guided practice problems. It covers incomplete dominance, codominance, and sex-linked traits.

Many consider cannibalism to be the last resort before starvation. During an engaging video, scholars gain knowledge of cannibalism in the animal kingdom. It addresses common misconceptions and recently discovered patterns before pupils...

Explore human genetics through the world of Harry Potter. A thorough lesson develops the introductory concepts of genetics using characters of the popular book series. Learners study topics from DNA and chromosomes to Punnett Squares and...

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,...

Learn how genetic variation occurs within prokaryotes through transformation, transduction, and conjugation. The instructor then explains how sexual reproduction in eukaryotes can lead to crossing over, random assortment, and random...

Young scientists explore Gregor Mendel's work on pea plants, his laws of segregation and independent assortment. They work through genetic problems and then finish by looking at Huntington's disease and genetic testing. 

Rules are not meant to be broken in genetics. Scholars learn to build Punnett squares to track the inheritance of dominant and recessive traits in an interactive animation activity. Online questions help individuals reflect on their...
