Intro to Chemistry 7.2: Gas Laws (2/2)
Join Award winning teachers Jonathan Bergmann and Aaron Sams as they interactively teach Chemistry. 7.2: The Main Gas Laws. This video will introduce students to Charles' Law which states that as temperature goes up, volume goes up. A " real-life" example of this law is shown with video of hot air balloons. ( 10:17)
Tree House Weather Kids: Clouds and Moisture
This is not a streaming video but an interactive online book. It could be used in the classroom in numerous ways and at numerous levels. This book discusses clouds and moisture. It is divided into 4 chapters: "Humidity," "Clouds," "Rain, Snow, Sleet, and Hail," and "Measure Precipitation."

RAND Publications: Science and Technology: Online Research
RAND is described as a nonprofit institution that helps improve policy and decision-making through research and analysis. And following its mission, the publications portion of the Web site helps disseminate the results of its work "as broadly as possible." The Science and Technology: Online Research publications page contains access to monograph/reports, documented briefings, conference proceedings, testimony, RAND Graduate School dissertations, issue papers, research briefs, white papers, and
A Well-Tested Eye in the Sky: What U-2 Spy Planes Do over Iraq that Satellites Don't
One of the most important pieces of technology being used to search Iraq for evidence of weapons is a 48-year old spy plane. The U-2, which was first flown in the beginnings of the Cold War, has withstood the test of time and continues to be widely used by the US. This site provides details about the history of the U-2. It also describes many technical aspects involved in flights, such as the advanced sensor systems and pilot life support.
Utah Geological Survey's Web site, Utah Geology, offers a variety of interesting geological information about the state. Good descriptions, illustrations, and photographs can be accessed on earthquakes and hazards, dinosaurs and fossils, rocks and minerals, oil and energy, and more. For example, the Rocks and Minerals page contains everything from how to stake a mining claim to downloadable summaries of mineral activity in the state. There is quite a bit of information within the site, and anyon
Modeling & Simulation
Modeling & Simulation is a journal published by The Society for Modeling and Simulation International. The Society has made its 2004 Modeling and Simulation Resource Guide available free to download. The directory provides descriptions and contact information for the many modeling and simulation software packages currently available, as well as listings for various modeling and simulation organizations worldwide. Two guest articles describe techniques for the application of real-time simulation
A Citizen's Guide to Understanding and Monitoring Lakes and Streams
The Washington State Department of Ecology?s Water Quality Program offers the Web site A Citizen's Guide to Understanding and Monitoring Lakes and Streams. The five chapters include the basic scientific knowledge needed to partake in water quality monitoring. For example, visitors can learn about parameters such as temperature, dissolved oxygen, and pH, as well as how to report and analyze the collected data.
NOAA Coastwatch Great Lakes Node
The National Oceanic and Atmospheric Administration's (NOAA) CoastWatch program provides near real-time satellite observations and in-situ Great Lakes data. Visitors can view AVHRR imagery, contour maps, GOES imagery, and other Great Lakes data imagery. The website offers data on the physical characteristics of the Great Lakes as well as data on the average surface water temperature and current and historic water levels. QuickTime movies illustrate changes in water temperature throughout a given
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.”
Lost in the Amazon
The Lost in the Amazon curricular unit is a series of minds-on and hands-on engineering activities based in the Amazon rainforest in Brazil. Motivated by an adventurous theme, students discover, learn and apply the following: 1) Classification of Plants and Insects; 2) General Categorizing Skills; 3) Process Skills: Problem Solving and Critical Thinking; 4) Scientific Testing and Experimentation; 5) Properties of Materials The investigative, exploratory and problem solving nature of Lost in the
Physical science is the science of matter and energy and their interactions and examines the physical world around us. Using the methods of the physical sciences, students learn about the composition, structure, properties, and reactions of matter and the relationships between matter and energy. Students are best able to build understanding of the physical sciences through hands-on exploration of the physical world.
This lab demonstrates Hooke’s Law with the use of springs and masses. The students attempt to determine the proportionality constant, or k-value, for a spring. The students do this by calculating the change in length of the spring as different masses are added to it. The concept of a springs elastic limit is also introduced, and the students must test to makes sure the spring’s elastic limit has not be reached during their tests in the lab. After compiling all of their data, they attempt to
How Much Water Do You Use?
Students keep track of their own water usage for one week, gaining an understanding of how much water is used for various everyday activities. They relate their own water usages to the average residents of imaginary Thirsty County, and calculate the necessary water capacity of a dam that would provide residential water to the community.
Ocean Water Desalination
Students learn about the techniques engineers have developed for changing ocean water into drinking water, including thermal and membrane desalination. They begin by reviewing the components of the natural water cycle. They see how filters, evaporation and/or condensation can be components of engineering desalination processes. They learn how processes can be viewed as systems, with unique objects, inputs, components and outputs, and sketch their own system diagrams to describe their own desalin
Analyze the Data
Students go through the logical process of quantitatively analyzing data from the FasTracks system. They gain experience identifying problems with the current design based upon their earlier observations and experiences in activities 1 and 2. Students discuss the flaws that they find in the system. This activity requires the use of the FasTracks Living Lab, a web portal to interactive train (transit) traffic data for a major metropolitan city.
Multicultural Math Fair
This website provides a collection of activities compiled by the Mathematics Department at Frisbie Middle School in Rialto, Calif. for use at its Multicultural Math Fair. Although the activities are from the 1999-2000 Multicultural Math Fair, the Math Forum maintains the website and all the links were current at the time of this report. The website includes some tips on how to set up a Multicultural Math Fair as well as data sheets and software for some of the activities, such as the Tower of Ha
Are You An Energy Efficient Consumer?
This activity engages students in learning about ways to become energy efficient consumers. Students examine how different countries and regions around the world use energy over time as reflected in night light levels. They then track their own energy use, identify ways to reduce their individual energy consumption, and explore how community choices impact the carbon footprint.
