An activity designed to enable the students to access the impact of oil-development on environmentin Alaska. Students will draw conclusion based on various data and reading various views.

A complete biography on the life of Ernest Rutherford, 1908 winner of the Nobel Prize for Chemistry. Details his education and his many scientific researches. Also contains a listing of his awards and achievements and has some information on his personal life.

This article aligns the concepts of Essential Principle 2 of the Climate Sciences to the K-5 content standards of the National Science Education Standards. The author also identifies common misconceptions about heat and the greenhouse gases effect and offers resources for assessing students' understanding of interactions among components of the Earth system. This article continues the examination of the climate sciences and climate literacy on which the online magazine Beyond Weather and the Water Cycle is structured.

In this computer lab, students use satellite imagery, daylength information, and phytoplankton physiology models to calculate annual primary production for an assigned ocean region.Satellite data is obtained from the NASA Earth Observation website. Students use the analysis tool to determine chlorophyll concentration and sea surface temperature. They also receive a day-length calculator and are asked to model light transmission through the water column. Using step-by-step instructions and proviede equations relating phytoplankton physiology to irradiance and temperature students calculate carbon uptake at discreet locations in the water column. The second half of the exercise involves scaling up to the entire water column, region, and season. Students present their work to the class and evaluate their result using scientific literature. Differences between regions are then discussed by the class.

Explore the concept of evaporative cooling through a hands-on experiment. Use a wet cloth and fan to model an air-conditioner and use temperature and relative humidity sensors to collect data. Then digitally plot the data using graphs in the activity. In an optional extension, make your own modifications to improve the cooler's efficiency.

In this NASA video, scientists describe how the Extreme Ultraviolet Variability Experiment will sample and track the Sun's ultraviolet irradiance, providing a detailed time sequence of extreme ultraviolet output -- data that can provide advance warning for potentially disruptive energy bursts.

In this adapted video segment, ZOOM guest Tommy takes us on a tour of the Florida Everglades. He describes what makes a wetland biome unique, including the soil, precipitation, and biodiversity.

How much radiation are we exposed to every day? Find out in this video segment adapted from FRONTLINE.

This lab activity leads students to a better understanding of exo-endo- thermic processes. It also reinforces the necessity for proper lab safety equipment and disposal techniques.

In this video segment adapted from NASA, students in Matsuyama City, Japan, interview Expedition 8 Commander and NASA Science Officer Mike Foale and Flight Engineer Alexander Kaleri about life and work aboard the International Space Station.

In this video segment adapted from ZOOM, the cast investigates how the pitch of sound changes when they strike a variety of glasses filled with different amounts and types of liquids.

Can a fresh lemon power a digital clock? In this video segment adapted from ZOOM, the cast shows you how this can be done and, in the process, discover how kids can be a part of an electric circuit.

This activity allows children to explore the effects of oil spills on birds.

This activity is a laboratory activity where students gather data relating quantities of salt to the freezing point of water/ice.

This is a teacher demonstration used to show an example of kinetic molecular energy using food coloring and water. The students are also given opportunity to develop their own questions and tests.

A lesson on states of matter using marbles for molecules expands into 3 more lessons elaborating on properties of a gas.

This is a teacher demonstration used to show an example of kinetic molecular energy using food coloring and water. The students are also given opportunity to develop their own questions and tests.

This activity provides for small group investigation of the properties of different liquids leading to the discovery that liquids are different in many ways, including density.Students would be led to a very beginning understanding of density.

Join Tarissa and Sabrina as they measure and compare the volume of different sounds across New York City in this video from DragonflyTV.

In this video segment adapted from Interactive NOVA, astronaut John Young experiences extreme temperatures on the Moon that are a result of the Moon's low gravity and lack of atmosphere.
