Other links lead to weather products, research, and articles from The Tropical Meteorology Project, Colorado State University Researchers, and the Tropical Storm Research community from around the world. There are also tropical storm frequently asked questions about typhoons, hurricanes, and oth
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
University of Iowa : burn oat hulls for economic, environmental benefit
What is an alternative energy source that is available today? This article, part of a series about the future of energy, introduces students to a pilot project of burning oat hulls at the University of Iowa power plant. Students read that the burning of oak hulls instead of coal provides for cleaner air and additional space in landfills. Copyright 2005 Eisenhower National Clearinghouse
Can students predict how many pretzels they can eat in a minute? This material is part of a series of hands-on science activities designed to arouse student interest. Here students learn that pretzels contain a saliva-absorbing compound and are asked to take that fact into consideration when predicting how many pretzels they can eat in a minute. The activity includes a description, a list of science process skills and complex reasoning strategies being used, and a compilation of applicable natio
Soil Litter: The Food Web
Teachers could incorporate this brief radio program into a variety of learning settings. For example, teachers living in the temperate deciduous forest biome can play the program for students when leaves begin to fall in autumn. The program could also be used whenever students anywhere are learning about food webs or soil. Teachers can choose to use either the audio or text version (or both) to give students listening or reading practice.
Everest : Test Your Brain
This interactive feature from the NOVA Everest Web site lets you take the same brain quizzes that researchers used to test the brain function of climbers on Mount Everest.
This unit is concerned with macroevolution – the patterns and processes of evolution above the species level. A crucial consideration in macroevolutionary studies is that of the evolutionary relationships (phylogeny) of the organisms in question. The unit begins with an introduction to the scope of macroevolutionary studies and illustrates methods of reconstructing phylogeny, from both morphological and molecular data.
In and Out Reactor
Students learn about material balances, a fundamental concept of chemical engineering. They use stoichiometry to predict the mass of carbon dioxide that escapes after reacting measured quantities of sodium bicarbonate with dilute acetic acid. Students then react the chemicals in a small reactor made from a plastic water bottle and balloon.
Graphing Equations on the Cartesian Plane: Slope
The lesson teaches students about an important characteristic of lines: their slope. Slope can be determined either in graphical or algebraic form. Slope can also be described as positive, negative, zero, or undefined. Students get an explanation of when and how these different types of slope occur. Finally, students learn how slope relates to parallel and perpendicular lines. When two lines are parallel, they have the same slope and when they are perpendicular their slopes are negative reciproc
Students design, build and test model race cars made from simple materials (lifesaver-shaped candies, plastic drinking straws, Popsicle sticks, index cards, tape) as a way to explore independent, dependent and control variables. They measure the changes in distance travelled with the addition of mass to the vehicles. Students also practice the steps of the engineering design process by brainstorming, planning, building, testing, and improving their “mint-mobiles.”
Designing Medical Devices for the Ear
Students are introduced to engineering, and more specifically, to biomedical engineering and the engineering design process through a short lecture and interactive, hands-on activity (approximately 30 minutes long), where students design their own medical device for retrieving foreign bodies from the ear canal. In this lesson, the teacher first reviews the basics of ear anatomy then discusses how ear infections occur and how they are treated. Following antibiotic treatment, the most common treat
Students use gumdrops and toothpicks to make lithium atom models. Using these models, they investigate the makeup of atoms, including their relative size. Students also practice adding and subtracting electrons from an atom and determining the overall charges on atoms.
Shapes of Strength
Students are introduced to brainstorming and the design process in problem solving as it relates to engineering. They perform an activity to develop and understand problem solving with an emphasis on learning from history. Using only paper, straws, tape and paper clips, they create structures that can support the weight of at least one textbook. In their first attempt to build the structures, they build whatever comes to mind. For the second trial, they examine examples of successful buildings f
Water, Water Everywhere
Students learn about floods, discovering that different types of floods occur from different water sources, but primarily from heavy rainfall. While floods occur naturally and have benefits such as creating fertile farmland, students learn that with the increase in human population in flood-prone areas, floods are become increasingly problematic. Both natural and manmade factors contribute to floods. Students learn what makes floods dangerous and what engineers design to predict, control and sur
All Caught Up: Bycatching and Design
Bycatch, the unintended capture of animals in commercial fishing gear, is one of the hottest topics in marine conservation today. About 25% of the entire global catch is bycatch. This surprisingly high level of bycatch is responsible for the decline of hundreds of thousands of dolphins, whales, porpoises, seabirds and sea turtles each year. Through this curricular unit, students will analyze the significance of bycatch in the global ecosystem and propose solutions to help reduce bycatch. Student
Reverse Phase HPLC Basics for LC/MS
This site provides a tutorial on practical reverse phase chromatography for LC-MS. Focusing on peptide and protein analysis, Andrew Guzzetta offers appropriate tips on mobile phase gradients, preparing your reversed-phase HPLC column for the first run of the day, and taking care of your column after the day's separations are complete. The site also provides a representative list of web-based resources on LC.
Discovering Properties of Matter
What is matter? How do we define it? What are some of its properties that we can measure? Come learn all about this fundamental piece of science in this Wowie clip from the Children's Museum of Houston. Cynthia briefly discusses the following properties of matter: shape, texture, magnetism, fluorescence, and mass. (0:59)
