Harness the power of bacteria. Scholars see how using organisms that exist in nature can help solve human problems in the process known as bioremediation. They research and discuss several successful examples, such as using oil-eating...

When life gives you mold, make penicillin. Scholars design an inquiry experiment to determine what causes rotting and mold growth. It also covers decomposers and the important role they play for other living things. 

Pathogens, what they are, how they spread, and how to prevent them from spreading are the focus of this resource that can be used to prepare learners for a performance task assessment or to begin the study of communicable diseases.

Risk-taking behavior and other decision-making factors may be influenced by more than just our brains; current research shows that the more bacteria that exists in one's digestive tract, the less inclined one might be to engage in risky...

Winogradsky columns are ideal for observing the role of bacteria and other microorganisms in an ecosystem. This student activity guide is complete with data tables for observations and analysis questions for processing what was observed....

Humans are like planets, hosting a plethora of microbial communities. This concept is explored with vivid narration and animation, bringing to light the benefits of the huge variety of microbes that live in and on our bodies. What a fun...

Small groups of life science learners look at Allison's symptoms and discuss a diagnosis. They use a chart of illnesses and draw symptom clues from an envelope to determine what illness she has. A lesson like this gives children an...

Mini microbiologists play a card game in which they group microorganisms by groups: virus, fungus, protist, or bacteria. Then they identify the roles different microbes play in the natural world and explore how humans effectively use...

Following directions from a colorful slide preparation card, beginning biologists examine three different live microorganisms: bacteria, yeast, and paramecia. This is not an unusual activity to do with your class, but if you are doing it...

Totally gross out your class with the eighth lesson in this series on food science. Explore the microscopic world of bacteria by taking swabs of different classroom objects and growing colonies in petri dishes. An engaging activity that...

Here is an unusual comparison: the swimming conditions of a sperm cell and a sperm whale. Introduce your physics class to the Reynolds number by sharing this video comparison during your fluid mechanics unit. Afterward, teach them to...

Mr. Spangler's sons set out to prove that double-dipping (putting a potato chip back into a dip for a second blob on the chip), does indeed rapidly spread germs throughout the entire dip. After viewing this presentation, the next time...

Look here for a narrative approach to cells origins and discovery by microscopes. Though it is a slightly older clip, it contains some lovely footage of cells up close. Begin with prokaryotes and move onto eukaryotes and the differences...

The differences between prokaryotic and eukaryotic cells are explained and the parts of each are highlighted. Discover the major organelles found in an animal cell and each of their functions. Paul Andersen does an excellent job once...

Mr. Spangler's sons set out to prove that double-dipping (putting a potato chip back into a dip for a second blob on the chip), does indeed rapidly spread germs throughout the entire dip. After viewing this presentation, the next time...

Learn how bacteria defends the body in this student-made video. Middle schoolers simulate how bacteria works in our bodies.

Where is bacteria found? See where bacteria and other microbes help and hurt humans. Microscopic images are shown along with images of people and places. Begin looking into this tiny universe with part one of a four-part series....

Radia Gleis continues to talk about metabolic markers, honing in on the colon. Gastrointestinal problems are discussed along with some reasons why these problems arise. Go into detail with your health or nutrition class about many of...

In part two of the "Origin and Evolution of Life," our host looks to the hot geysers found in Yellowstone to show the type of environment primordial life may have evolved from. This leads to an explanation of how scientist Stanley Miller...

Bacteria are described here as little factories, or programmable robots, that can be used to put instructions into for genetic engineering. Professor M. Rahman gives a brief explanation of bacteria and how they are used for genetic...

If you are interested in exploring commercial food production with your upper-elementary or junior high schoolers, here is a video about how yogurt is made. It takes you through the processing of the fruit and the milk, as well as the...

Marshall Brain uses a sponge, rope, and other common household items to display the workings of the digestive system. This resource would definitely hold the attention of a squirrely junior high class!

Colorful pictures and animation accompany a thorough explanation of the digestive process. Each anatomical part of the digestive system is explained as well as the chemical signals that are affiliated with digestion and absorption....

There's no need for bacteria hysteria! With this flashy, gourmet-cooking-show-style video, young bacteriologists find that there are tremendous amounts of microbes in different foods that we eat and inside our bodies. Kitchen instruction...
