Garbage, recycle, compost: Does it really matter where we put our trash once we are done? By making detailed observations over seven weeks, kids will see which materials break down naturally to become a healthy part of the soil, and...

It's hard to imagine that anything was missed on this five-page list of science roots, prefixes, and suffixes! Listed in alphabetical order, all are included in a single, two-column list. This may be especially useful for advanced...

Cultivate bacteria with a straightforward lesson featuring agar. Scholars create a streak plate on agar to ideally create colonies of bacteria or yeast that are growing separately from each...

In the 1940s, scientists discovered bacteria conjugation, the process of DNA transfer or bacterial sex. The discovery proved that bacteria and viruses contain DNA and led to a Nobel prize. Interested individuals learn about the...

A series of questions about archaebacteria and eubacteria reinforce a chapter on viruses and bacteria. This worksheet is from chapter 18 of an unspecified textbook, but could work with your biology lecture as well. High schoolers...

Use this great overview to give information on all aspects of nutrition. By working their way through this PowerPoint, students review a lot of information about the digestive process.  Students read many facts on a number of...

In this genetic activity, students will match 6 terms associated with gene engineering to their correct definition. Then students will complete a table indicating if the vector is mechanical or biological. Finally, students will complete...

In this quantitative analysis worksheet, students explore the limits of a rate equation. They use quantitative analysis methods to determine the differential, plot graphs of their values, and describe the relationships between the...

Young scholars compare characteristics of myobacteria and viruses to determine which is the smallest life form. They read and discuss an article that presents different viewpoints on the definition of life to determine their own viewpoint.

Students study nanotechnology and investigate the dimensions of a nanoscale.  In this nanometer study activity students will see how truly small a nanometer is by measuring things such as a piece of hair.

Investigate the similarities and differences between gram positive and gram negative bacterial cells.

Learn about gram staining and the characteristics of gram-negative bacteria. A discussion of cell wall structure is accompanied by a labeled illustration. Includes a list of examples of gram-negative bacteria organized by subgroup....

This article focuses on the bacterium that causes whooping cough, Bordetella pertussis. It discusses how the bacterium effects the human body at it goes through various stages: colonization and the toxemic stage. Look at charts and...

Bacteria are single celled microbes. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. Instead their control centre containing the genetic information is contained in a single...

This site provides an introduction to bacteria and examines fossil records, life history and ecology, systematics, and morphology.

Discover new knowledge about molecular biology- how molecules fit together as a lock and key. This has given researchers new diagnostic tools that use immune cells from mice to produce antibodies to detect a specific virus or bacterium.

Discover the world of bacteria from their importance in the development of more complex life forms to how they use flagella to move. Highlights the characteristics of cyanobacteria.

This competent site delves into the size of bacteria, shapes of bacteria, arrangement of bacteria, and how and what bacteria eat.

Take an interactive quiz over bacteria. After completing the quiz, check your score, and then revisit any incorrect question for further review.
