Rain Forest In Brazil, which houses 30 percent of the remaining tropical rain forest on Earth, more than 50,000 square miles of rain forest were lost to deforestation between 2000 and 2005. Biologists worry about the long-term consequences. Drought may be one. Some rain forests, including the Amazon, began experiencing drought in the 1990s, possibly due to deforestation and global warming. Efforts to discourage deforestation, mainly through sustainable-logging initiatives, are underway on a very limited basis but have had a negligible impact so far. Experiments Below are interactive experiments that can be used to teach all ages about the art and science of space-based remote sensing. The experiments focus on how NASA uses remote sensing to study how and why the Earth changes. Mission: Biomes The following two activities are designed for teachers to use in classrooms as supplementary, interdisciplinary units. Mission: Biomes is especially appropriate for grades 3 through 8, and is designed to be interactive and self-correcting which will allow each student to work at his or her own pace. Great Graph Match
Exhibits Collection New Englanders have a saying: "If you don't like the weather, just wait a minute." Weather forecasts may be more stable in other parts of the world, but the basic idea stands. Weather is dynamic, the product of interacting forces we are only beginning to understand. Witness the weather extremes caused by El Niño in 1997 and 1998. Talking Glossary of Genetic Terms Glossary Home | Text Version Designed to help learners at any level better understand genetic terms Guided by national science standards Explained by scientists at the NIH The National Human Genome Research Institute (NHGRI) created the Talking Glossary of Genetic Terms to help everyone understand the terms and concepts used in genetic research. In addition to definitions, specialists in the field of genetics share their descriptions of terms, and many terms include images, animation and links to related terms. Enter a search term or explore the list of terms by selecting a letter from the alphabet on the left and then select from the terms revealed.

Rain Forest Threats, Rain Forest Species More than half of Earth’s rain forests have already been lost forever to the insatiable human demand for wood and arable land. Rain forests that once grew over 14 percent of the land on Earth now cover only about 6 percent. And if current deforestation rates continue, these critical habitats could disappear from the planet completely within the next hundred years. The reasons for plundering rain forests are mainly economic. Wealthy nations drive demand for tropical timber, and cash-strapped governments often grant logging concessions at a fraction of the land’s true value.
Ecosystems We're All in This Together Everything in the natural world is connected. An ecosystem is a community of living and non-living things that work together.

Rainforest Biomes The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly. Rain forests belong to the tropical wet climate group. The temperature in a rain forest rarely gets higher than 93 °F (34 °C) or drops below 68 °F (20 °C); average humidity is between 77 and 88%; rainfall is often more than 100 inches a year. There is usually a brief season of less rain. biotic and abiotic As of July 1, 2013 ThinkQuest has been discontinued.

The Energy Story - Introduction Energy is one of the most fundamental parts of our universe. We use energy to do work. Energy lights our cities. Energy powers our vehicles, trains, planes and rockets. Energy warms our homes, cooks our food, plays our music, gives us pictures on television. Energy powers machinery in factories and tractors on a farm.
The Photosynthesis Cycle" The Earth's atmosphere is mostly composed of nitrogen. Oxygen makes up just 21 percent of the air we breathe. Carbon dioxide, argon, ozone, water vapor and other gasses make up a tiny portion of it, as little as 1 percent.
