On the Microbe Trail: An Introduction to Bacteria and Aseptic Technique

Keep your hands on the wheel—at all times! Scholars learn why pilots use a flight computer through a high-flying demonstration. Making calculations for speed, distance, or time is automatic if you know how to use a flight computer. 

Beginning biologists survey several websites to learn about the types, structure, motility, feeding habits, and reproductive methods of bacteria. All websites are linked to the lesson plan, so you can have individuals access it and click...

Young scientists enter the world of microscopic organisms with this introductory presentation on bacteria. Starting with a basic definition of these single-celled organisms, the presentation continues on to explore different types of...

The first slide lists the six kingdoms in the biological hierarchy, but the remaining 10 slides cover characteristics of archaebacteria and eubacteria. Topics include how energy is obtained, arrangement, and shape. This brief, but...

Can pesticides affect humans, even if they don't eat the crops that were sprayed? Silent Spring, Rachel Carson's 1962 work on the environmental effects of DDT, discusses the ways that bioaccumulation creates a path from a dangerous...

Ready to begin cell biology in a grand fashion? Start the adventure using a short but thorough video from a vast biology playlist! From prokaryote to eukaryotes, Golgi to chloroplast, the narrator guides viewers through the cell membrane...

The evidence for natural selection is presented as a random variation of a characteristic allowing a particular strain of organism to survive with a higher probability of successful reproduction. Population change over a short period of...

The average human body loses 40–100 strands of hair in one day. This is the first video in a series of 47 and introduces scholars to anatomy and physiology, the study of the human body, and how it works. The narrator shares the history...

Young scholars are able to define microbes and identify the five main groups of microbes. They are able to give examples of ways in which microbes have impacted or currently impact human life. Students are able to explain that not all...

Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...
