Superbugs

Pupils review procedures for handwashing and explore the connection between microbiology and improved health care. They examine bacterial culture grown from bacteria under their fingernails and write a procedure for handwashing in a...

Discover a world too small to see. In the lesson, young scientists learn about nanotechnology and brainstorm ideas for new applications of it. They perform an activity to determine how surface area changes when objects are made smaller...

Nano-nano! Nanotechnology can seem like it's from another planet! After learning about this tiny technology, collaborative groups experiment with how smaller particles affect chemical reactions. They do this by immersing a whole and a...

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...

"To understand the present, we have to imagine the future." In his final video in the series, the narrator discusses an array of considerations tied to globalization, such as the implications of individualism, our impact on the...

The narrator of a short video shows learners the history of antibiotics with the use of penicillin. Viewers then see how bacteria are becoming resistant to antibiotics and what that means for our future health and for the development of...

Learners demonstrate safe ways to handle bacteria, prepare agar plates, and grow bacterial cultures. They identify different kinds of bacterial colonies, and devise a controlled experiment.

Students compare bacteria and viruses and their roles in biotechnology and bioterrorism. They outline fundamental steps of bacterial transformation and the possible selection processes to identify transformants. They discuss...

Learners explore disease and its relationship to history and literature. They investigate issues that range from early biological warfare and historical disease treatments, to observing today's race for the cure against current emerging...

Learners complete experiments on antibiotics and antimicrobials. In groups, they explain how antibiotics affect the evolution of microorganisms. They test various types of bacteria to discover how much resistance they have to antibiotics.
