Case Study – Sleepless, Not Tired
Ever wish your students were as engaged with biology as they are with Netflix? What if you could teach them about brain anatomy, genetics, and sleep regulation—all through the story of a real-life “super sleeper”? Enter “Sleepless, Not Tired”, a classroom-ready case study that follows Lena, a college freshman who only needs five hours of…

Solving Crimes with DNA and Electrophoresis
DNA analysis has become a cornerstone of modern forensic science. Because every individual (except identical twins) has a unique DNA profile, scientists can use DNA evidence from crime scenes to help identify suspects or eliminate individuals from suspicion. One common method for comparing DNA samples is gel electrophoresis, a technique that separates DNA fragments based…

How Does CRISPR Work? A Coloring Activity
Gene editing might sound complex, but what if you could color your way to understanding it? CRISPR-Cas9 is a gene-editing tool that allows scientists to precisely cut and modify DNA. Inspired by a natural defense system in bacteria, CRISPR uses a guide RNA (gRNA) to direct the Cas9 protein (a molecular scissor) to a specific…

Cystic Fibrosis – Overview and Genetics
Cystic fibrosis (CF) is a genetic disorder that affects the lungs, digestive system, and other parts of the body. Mutations in the CFTR gene on chromosome 7 leads to the production of thick, sticky mucus that can block airways and digestive ducts. Patients deal with lung infections and lack of nutrition because the mucus interferes…

Genetics Practice – Roan Cows with Horns
Practice genetics with cows! Cows can be horned (hh) or hornless. They can also be red, white, or roan colored.

Peas, Please! – A Practice Set on Mendelian Genetics
Students practice assigning genotypes (PP, Pp, or pp) to different traits based on whether the trait is dominant or recessive. They set up Punnett squares, and determine the phenotypic ratios of the offspring.

Case Study – The Genetics of Eye Color
A case study exploring the genetics of eye color. Students review a pedigree and examine the role of HERC2 and OCA2 in eye color inheritance.

Investigation: DNA, Proteins, and Mutations
Explore DNA mutations by transcribing and translating DNA code. Changes in the code result in point mutations, frameshift, and nonsense mutations.
