If you’re a first-year teacher or new to teaching gel electrophoresis , here’s some truth: it can feel overwhelming the first time. You're juggling: 🧪 Complex procedures 🧫 Expensive or limited materials 🧍 Classroom management while running a lab 📝 Ensuring students actually understand what's happening—not just copying answers And yes— prep takes time . ⏳ Why Gel Electrophoresis Labs Take Longer to Prep Unlike simple demos or guided notes, gel electrophoresis involves: Making or purchasing agarose gels Dye or DNA sample preparation (often requires simulated DNA) Setting up electrophoresis chambers , wires, and power supplies Labeling sample lanes and preparing lab groups Managing cleanup of expensive or delicate equipment And that’s before students even step into the lab. If you’re low on budget or time, it's completely okay to simulate the process using printable or digital materials first. That’s why I designed my electrophore...
If you're getting ready to teach one of the most fundamental (and sometimes frustrating) units in biology— biomolecules —you’re not alone! Proteins, carbohydrates, lipids, and nucleic acids are key to understanding so many life processes, but many students struggle to keep them straight. The good news? You don’t have to start from scratch. Below are seven classroom-tested, no-prep resources (printable and digital) that make biomolecules clear, fun, memorable —and how to use a few of my favorite TPT resources to make the content interactive, visual, and accessible for all learners. Understanding biomolecules —carbohydrates, proteins, lipids, and nucleic acids—is the key that unlocks later units like enzymes, cellular respiration, and genetics. Yet many students struggle to keep these macromolecules straight. Why Teaching Biomolecules Matters Keyword: why teach biomolecules in biology Biomolecules are the building blocks of life. Without a solid understanding of these m...
