Understanding the Evolution of Limbs in Snakes
Where did snakes come from? There’s a popular story about snakes in Ireland and how they were lead away by St. Patrick. From a science perspective, snakes likely never were in Ireland to begin with. Many islands don’t have snakes. Why? Because they haven’t had time to evolve there. The activity is adapted from Understanding…

Top 10 Classroom Pets
Many science teachers have classroom specimens (or pets) to serve as model organisms, to teach students how to care for animals, and to generally liven up the space. When I first started teaching, I inherited a room that had beautiful cabinets full of specimens preserved in formaldehyde. I wanted a pet in that space…

Taxonomy – The Science of Classifying Organisms
Why do we need a system to classify and name organisms? Here are some common names: Common names can be misleading. A sea monkey is a type of shrimp. A spider monkey is not a spider, and a sea horse is fish. Sea cucumbers are strange little invertebrates that are related to starfish. Common names…

Evolution & Taxonomy
Evolution is often called the “unifying theory of biology” because it organizes all of the observations gathered by biologists and proposes and explanation for those observations. All state standards for teaching science include a section on evolution (sometimes called adaptation or change over time). Related Page: Animal Groups – Organized by Phyla Evolution Evolution: Fact,…
