    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

    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

    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…
