Nonindigenous Aquatic Species
This US Geological Survey database provides information on nonindigenous aquatic species for resource professionals and the general public. Distribution maps and species information for a variety of aquatic vertebrate, invertebrate, and plant species includes photos, description of the life cycle, native and non-native habitat range, and potential impacts the non-native species has on its habitat. The site is easy to navigate; users can find information by species name, state, or drainage basin.
What You Always Wanted to Know About Salt
The What You Always Wanted to Know About Salt Web site is maintained by the nonprofit organization the Salt Institute. Information on nearly every aspect of salt can be found here, including salt facts, properties of sodium chloride, salt deposits in the US, the various uses of salt, salt in the winter, the history of salt, and much more.
The US Department of Interior Web site offers a hot topics section that currently includes information about coalbed methane. The links include a fact sheet entitled "Coalbed Methane--An Untapped Energy Resource and an Environmental Concern." A documents link takes visitors to a page maintained by Wyoming's Bureau of Land Management that contains several reports related to the topic, including information about Atlantic Rim Coalbed Methane Projects and Coalbed Methane and Water Monitor Well Data
The Space For Nature Wildlife Gardening Forum
This informative Space For Nature Wildlife Gardening Forum website was developed for naturalists, horticulturalists and others interested in creating garden habitats for wildlife. The site editor is Richard Burkmar, who received his PhD from University College of Cardiff in avian ecology, and believes "that gardens are an increasingly valuable habitat in real terms for wildlife, and that they are uniquely positioned, as accessible natural spaces, to influence our behaviour and attitudes towards
The Paleontological Society
The Paleontological Society, an international non-profit organization founded in 1908, created this Web site devoted to the advancements in paleontology. The site allows paleontologists access to abstracts in a few journals including Paleobiology. Prospective students will discover grant opportunities. Media representatives with questions about the history of life on earth can find contacts for paleontologists. Scientists can also learn about the society's Distinguished Lecture Program, which fe
Building Tetrahedral Kites
Working in teams of four, students build tetrahedral kites following specific instructions and using specific materials. They use the basic processes of manufacturing systems – cutting, shaping, forming, conditioning, assembling, joining, finishing, and quality control – to manufacture complete tetrahedral kites within a given time frame. Project evaluation takes into account team efficiency and the quality of the finished product.
Students learn that wind and storms can form at the boundaries of interacting high and low pressure air masses. They learn the distinguishing features of the four main types of weather fronts (warm fronts, cold fronts, stationary fronts and occluded fronts) and how these fronts are depicted on a surface weather analysis, or weather map. Students also learn several different ways that engineers help with storm prediction, analysis and protection.
Students observe and discuss a simple model of a wet scrubber to understand how this pollutant recovery method functions in cleaning industrial air pollution.
Surfactants: Helping Molecules Get Along
Students learn about the basics of molecules and how they interact with each other. They learn about the idea of polar and non-polar molecules and how they act with other fluids and surfaces. Students acquire a conceptual understanding of surfactant molecules and how they work on a molecular level. They also learn of the importance of surfactants, such as soaps, and their use in everyday life. Through associated activities, students explore how surfactant molecules are able to bring together two
The purpose of this activity is to demonstrate some of the different parts of an airplane through the construction of a paper airplane. Students will build several different kinds of paper airplanes in order to figure out what makes an airplane fly and what can be changed to influence the flying characteristics of an airplane.
Students learn about weight by building a spring scale and observing how it responds to objects with different masses.
Ramp and Review
In this hands-on activity — rolling a ball down an incline and having it collide into a cup — the concepts of mechanical energy, work and power, momentum, and friction are all demonstrated. During the activity, students take measurements and use equations that describe these energy of motion concepts to calculate unknown variables, and review the relationships between these concepts.
Seismic Waves: How Earthquakes Move the Earth
Students learn about the types of seismic waves produced by earthquakes and how they move the Earth. The dangers of earthquakes are presented as well as the necessity for engineers to design structures for earthquake-prone areas that are able to withstand the forces of seismic waves. Students learn how engineers build shake tables that simulate the ground motions of the Earth caused by seismic waves in order to test the seismic performance of buildings.
Go Public: Osteoporosis Brochure
Students will answer the Challenge Question and use the acquired learning from Lesson 1, “Fix the Hip Challenge” and Lesson 2, “Skeletal System Overview”to construct an informative brochure addressing osteoporosis and the role biomedical engineering plays in diagnosing and preventing this disease.
Where Am I: Navigation and Satellites
How do we know where we are? What happens if you are completely lost in the middle of nowhere? Does technology provide tools for people lost in their travels? A person cannot usually determine an accurate position just by looking out a window in the middle of the ocean or vast area of land, particularly if it has not been charted before. In this lesson, students explore the concept of triangulation that is used in navigation satellites and global positioning systems designed by engineers. Also,
What is Energy?
With an introduction to the ideas of energy, students discuss specific types of energy and the practical sources of energy. Hands-on activities help them identify types of energy in their surroundings and enhance their understanding of energy.
Thinking Green: Grow Your Own
This resource guide from the Middle School Portal 2 project, written specifically for teachers, provides links to exemplary resources including background information, lessons, career information, and related national science education standards. Student engagement with agriculture and gardening can not only fill a knowledge gap but also tap in to the affective domain. Students can get involved in community gardens, or collaboratively plan, plant, and cultivate a school garden, indoors, or out.
Earth on Edge : Ecosystems
This site provides information about the six ecosystems on which life on Earth most heavily depends: agricultural, forest, freshwater, grassland, coastal, and urban. It is part of a Public Broadcasting System (PBS) project, which includes a discussion guide. Ecosystems are described as communities of interacting organisms and the physical environment in which they live. The goods and services that ecosystems provide are said to form the foundation of human economies. Ecosystems purify air and wa
Guidelines for Integrating Comprehension-Based Word Study in Content Classrooms
Traditional approaches to vocabulary instruction are linear and may not help students develop deep understanding of words and retain their meanings. Vocabulary literacy is an approach to word study that engages students in word study and helps strengthen the connection between vocabulary learning and reading comprehension.
Hurricanes 2: Tracking Hurricanes
The purpose of this lesson is to examine the role of technology in identifying and tracking hurricanes. It is the second in a two-part series on the science of hurricanes and the kinds of technology being used to identify and track them. Students broaden their study by exploring how technology and science are used today to identify, measure, and track powerful tropical storms to better warn and secure people from a hurricane's often-devastating impact.
