This Substitute Teaching plan is straightforward: 1.) Print off enough copies of the handout for all students 2.) Take attendance 3.) Start the video: https://youtu.be/-KsDT0W6T2o?si=rGIzO_fTC6vWPtoi 4.) Students answer the questions while the video goes. They’re graded for getting the questions correct. It’s due at the end of the class period. Questions to Follow Through: Answer…

Teaching atomic theory without physical models is like trying to explain architecture without ever showing a building. Atoms are fundamentally abstract. Students can’t see them, touch them, or directly observe their behavior. As a result, many students fall into a pattern of memorization—atomic numbers, electron configurations, periodic trends—without ever forming a mental model of what…

When we look at the world around us, we gather information in two main ways: by observing and by inferring. An observation is something you can directly notice using your senses (see, hear, smell, taste, or touch) or measure with a tool. Observations are based on clear evidence. For example: “The goat is standing by…

Let’s be honest—when you hear “science fair,” you might picture stress, glue sticks, and last-minute chaos. But done right, science fairs are actually one of the most engaging and meaningful experiences you can give your students. Students remember their science fair project, but they may forget what “parthenogenesis” means. Science fairs turn students into real…

In this activity, learners will create their own rules to establish what “life” is by sorting everyday objects into categories. You are a living person. The air in your lungs is not alive. The paper in your notebook used to be alive when it was a plant. When we study “life science” and biology, we…

Why speed matters Most cryopreserved cells are frozen in medium containing DMSO, which protects cells during freezing but is toxic to cells once they are thawed, especially at room temperature or 37 °C. For this reason, the thawing process should be quick and deliberate, and DMSO should be diluted and removed as soon as possible…

Aseptic Technique: Keeping Cell Cultures Clean and Healthy Aseptic technique refers to the set of practices used to prevent contamination from microorganisms such as bacteria, fungi, and yeast when working with cells. Because cell culture media is warm and nutrient-rich, even a tiny lapse in technique can allow contaminants to grow quickly and ruin an…

Biosafety Cabinets: Working Safely and Cleanly A biosafety cabinet (BSC) is the primary workspace for cell culture and other sterile biological work. Its purpose is to protect you, your samples, and the laboratory environment while you work. Whenever you handle cells, media, or other biological materials, the biosafety cabinet is where that work should happen.…

You’ve taken your first steps into a clean room where cell culture takes place. Let’s get you acquainted with one of the most important components of cell culture: the incubator. Incubators: Where Cells Grow A cell culture incubator is one of the most important pieces of equipment in a cell culture laboratory. Its job is…
