Microorganisms are all around us, with an amazing diversity of adaptations. They were the first life on Earth, and their relatively recent discovery in extreme environments—like hot springs, ocean vents, and polar ice—illustrates how tenaciously they've evolved and survived. Microbiology gives us insights into evolution, disease, and even the mechanisms of our own cells.
Unsure of what the steps of the scientific method are? Not sure how to apply the scientific method? Watch how we use the scientific method to explore the science of popping boba – fun juice filled balls that pop in your mouth. You can find more information about each step of the scientific method at https://sbgo.org/steps-of-the-scientific-method

See a clear example of Jaccard similarity, also called the Jaccard index, in this tutorial video. I begin by demonstrating a visual example with a grocery shopping trip and sharing the definition of Jaccard similarity. We see the Jaccard similarity formula and use it to compute the Jaccard index between our two sets: the grocery list vs the grocery purchases. Then we explore two other example applications. First, we calculated the Jaccard similarity for two text documents. And we will…
What is a CFU (colony forming unit), and how does it relate to a bacterial colony that we can see on an agar plate. In this video this foundational concept in microbiology (key in both research and diagnostics!) is explained.
Learn how to make a glass spreader and aseptically spread an aliquot of bacteria evenly onto the surface of an agar plate.
Have you ever seen a real virus? Probably not – they are too tiny to see. But how big or small are viruses really? You can make a scale model to find out and compare the size of a virus to many other small objects. How much bigger do you think a pencil dot is compared to a coronavirus? Written instructions as well as the Scaling Chart and the Units and Conversion Table are available on our website at https://www.sciencebuddies.org/stem-activities/virus-scale-model?from=YouTube.
Simpson's Diversity index is a value that represents the species diversity (a type of biodiversity) in a location, generally with the purpose of comparing it to another location, or to compare the changes in a single location over time.
This video outlines how to use Simpson's reciprocal index (one of several variations on the same index).

When you get the flu, viruses turn your cells into tiny factories that help spread the disease. In this animation, NPR's Robert Krulwich and medical animator David Bolinsky explain how a flu virus can trick a single cell into making a million more viruses.

Next Generation Sequencing (NGS) of 16S variable regions is a powerful tool for analysing bacteria in a mixed sample. This simple video explains how it works
Do you know about your microbiome? This army of microbes fights for you, and sometimes when things get out of whack, it can fight against you. Learn all about your microbiome and what it can do for you in this fascinating new episode of SciShow, hosted by Hank Green!
