Abstract: This article written by Richard Monastersky of Science News Online describes the work of Martin Sharp of the University of Alberta and colleagues from the United Kingdom. This group began searching for cold-loving bacteria after their discovery of unexplainable chemical reactions beneath the ice of a Swiss glacier. Included in this online article are links to further readings by Monastersky which are related to sub-surface "deep dwelling" bacteria, and other Science News Online articles

Additional Information
Reviews
- How did you use this material?
This material could potential be used in my Biology classroom. The material is an article that focuses on species of bacteria that live under glaciers.
- Did you augment the material?
No I did not augment the material in any way.
- In which courses or programs did you use the material?
This material is only being used to write a review for a technology class. I have not actually used the material in my classroom.
- Clarity
Yes, this article is very clearly written and includes a list of references. Students would be able to read this material without making any changes to the original text.
- Consistency
Yes, the language is consistent with the language that most biology textbooks and biologists use.
- Content Errors
No, I did not find any errors.
- Interface
No, I found no such issues.
- Suggested Changes
The only suggested change I have is to change the text to a slightly darker color so that it contrasts more with the background and makes it easier to read.
- Exemplary Features
At the end of the article, there are references, further readings, and sources listed. I think that this information provides support for the content of this article.
- How would you recommend using this material?
I would recommend having students read this article after they have learned about the diverse environments in which bacteria live. Students could then engage in discussion of the possibility of bacterial life on other planets.
- What knowledge and skills do you need?
You need to know the term thermophilic. You also should have some basic knowledge of the characteristics of bacteria and glaciers.
- Is the material appropriate?
This material is probably most appropriate for students in grade 9 or higher. The article may also be suitable for the general population of people who have had exposure to some science in the classroom.
- Did using the material lead to successful or identifiable outcomes?
I have not used the material in my classroom.
