Ice Cube of Exotic Microbes
This article describes a permafrost subglacial lake discovered beneath Antarctica. The lake offers scientists a chance to test their sterile drilling techniques before exploring elsewhere in search of exotic microbes. Techniques that avoid contaminating a drill site with microbes, suggests the author, would prove useful for future drilling into Mars polar caps in search of life.
This website reviews several types of pollination and includes many photographs of flowers which depend on each type. It give a brief description of why each flower is appealing to its pollinator.
Students solve and reduce fractional equations by playing Soccer Shootout.

Methods and Strategies : Using Models Effectively
Models are crucial to science teaching and learning, yet they can create unforeseen and overlooked challenges for students and teachers. This article guides students through age-appropriate, critical analyses of instructional models.
PBS provides students in grades 4-7 with oodles of science fair ideas and a science fair tip sheet in this section of the DragonflyTV web site. Overviews of investigations from the television show are offered to help students hone in on an interesting topic and create their own science fair project. Each overview relays a question that a child asked on television, the main steps in his or her experiment, and the results. The overviews also include ideas for further investigations that build on t
Box and Whisker Plots
Construct a box-and-whisker plot to match a line plots, and construct a line plot to match a box-and-whisker plots. Manipulate the line plot and examine how the box-and-whisker plot changes. Then manipulate the box-and-whisker plot and examine how the line plot changes.
Factsheets emphasize the meaning of place value in division, the concept of division as repeated subtraction, division by 10 and 100, and well explained examples of both short and long division. A game as well as worksheets and quizzes are provided for practice.
Quick take on the wide, wide world of geometry
As the social studies, art, and music classes in the middle school widen students horizons, some of your students may become fascinated with the art, costumes, and customs of other peoples in this and other times. The NCTM Principles and Standards calls for middle school students to be able to recognize and apply geometric ideas and relationships in areas outside the mathematics classroom, such as art, science, and everyday life.
All About Sea Ice
Launched by the National Snow and Ice Data Center, the All About Sea Ice website is designed as an introduction to sea ice: what it is, how it forms, how it is studied, how it affected historical expeditions in the polar regions, and what role it plays in the global climate. The site contains over 80 pages of information on sea ice, including a glossary of sea ice terms and links to more information. The primary focus of the site is as a resource for the general public, educators and students in
Quick take on safety in the science classroom
With the increasing emphasis on hands-on instruction, it becomes more important than ever before for science teachers to be knowledgeable about laboratory safety issues. The National Science Education Standards say that students should have frequent opportunities to use a wide range of equipment, materials, supplies, and other resources for experimentation and direct investigation of phenomena. The National Science Teachers Association recommends that a minimum of 80 percent of science instructi
