USGS Biological Resources: National Activities
The mission of the United States Geological Survey's Biological Resources Discipline involves working with others to provide the scientific understanding and technologies needed to support the sound management and conservation of our Nation's biological resources. This website contains a comprehensive listing of biological research taking place within the USGS biology branch. This portal provides access to the National Bird Banding Project, the National Park Service flora and fauna database, the
Land Use History of North America
This site examines how we have used land since the 1700s and how the land has changed. Topics include population settlement and farmland, urban sprawl and soil resources, flora species, urbanization in the Baltimore-Washington corridor, landcover changes in the Great Lakes region, vegetation along the upper Mississippi River, biodiversity in the Yellowstone ecosystem, and landscape changes in the Southwest.
055 Special Exhibition: Velázquez Rediscovered
The Metropolitan Museum's European paintings chairman, Keith Christiansen, and head of paintings conservation, Michael Gallagher, discuss their recent reattribution of an extraordinary portrait in the collection to the greatest of all Spanish painters.
Applying Ohm's Law to Semiconductors
This project allows students to apply concepts of momentum conservation and energy conservation from classical physics. However, here they are not enough: they must be combined with modern physics, using concepts from relativity and particle physics as well as modern units that put energy, mass, and momentum in terms of MeV and GeV. Most important, students will learn about both fundamental and cutting-edge physics by actually doing what physicists do.
Tropical Ecology and Conservation
This seminar plus field work in Costa Rica is designed to give students with an in-depth understanding of tropical ecology and conservation biology. More specifically it provides students the opportunity to (1) read the original literature, (2) give oral presentations, (3) design and write a research proposal, and (4) gain hands-on research experience in Costa Rica. Here are what the students say are the highlights of the course: 1. Learning how to write a proposal and executing that project. 2.
Conserving Water at Home
This video segment adapted from Last Oasis highlights the impact of a variety of water conservation efforts including installing low-flow toilets and planting grass that does not require a lot of water.
Ready, Set, Escape
During this project, students will be asked to design a device that will measure out a time period of exactly 3 minutes. They will be asked to brainstorm ideas using the different materials provided. Students will observe and explain the effects of conservation of energy.
Energy Skate Park
Learn about conservation of energy with a skater dude! Build tracks, ramps and jumps for the skater and view the kinetic energy, potential energy and friction as he moves. You can also take the skater to different planets or even space!
Home Water Use
This lesson provides an overview of water use in the industrialized world, including a discussion of the increasing need for conservation as populations grow and water supplies stay roughly constant.
This lesson builds upon the previous two (Newton's Second Law and the First Law of Thermodynamics) by explaining that conservation of energy is not perfectly observed, in that energy is lost as it is transferred from kinetic to potential, and vice-versa.
Energy at Play
In this activity students will design a contraption using Tinker ToysTM, while exploring how Potential and Kinetic Energy are transformed and transferred. They will also gain a deeper understanding of the Law of Conservation of Energy.
Chemical Changes and Conservation of Matter
Where does the weight go when we “lose weight”? What happens when iron rusts? Why are exploding stars able to turn other elements into gold when the alchemists w
Species are being lost at a rapid rate in rainforests and coral reefs. Yet many species still have not been discovered. Tropical scientists struggle to keep ahead of the bulldozers as they work to understand this complex ecosystem. And an ocean biologist predicts the death of life and the "rise of slime" in the sea. How can we protect the biodiversity of these vulnerable
Energy and Eccentricity
The precise orbit of any heavenly body -- a planet, asteroid, or comet -- is fixed by the laws of conservation of energy and angular momentum. The eccentricity, which determines the shape of an orbit, is intimately linked to the energy and angular momentum of the heavenly body.
With current extinction rates exceeding those of previous mass extinctions, many biodi versity studies focus on efforts to count the Earth’s species before they are lost. This session explores current field experiments studying complex ecosystems and how environmental and biodiversity changes might affect their functions.
Baboons in Their Natural Habitat
A day in the life of anubis, or olive baboons (Papio anubis), filmed in the Ngorongoro Conservation Area, Tanzania. Shows animals eating, resting, climbing, and grooming.
Documentary- After 60 years in exile, three sisters return to the home that was taken away from them by the South African government. Their return home is part of Africa's conservation efforts- to get people back in their homelands.

Recycle your Cans!
The California Department of Conservation encourages you to recycle bottles and cans with this cute, 30 second video about a "talking" can that is eventually recycled into a baseball bat.
Web Soil Survey
Web Soil Survey (WSS) provides soil data and information produced by the National Cooperative Soil Survey. It is operated by the USDA Natural Resources Conservation Service (NRCS) and provides access to the largest natural resource information system in the world. NRCS has soil maps and data available online for more than 95 percent of the nation’s counties and anticipates having 100 percent in the near future. The site is updated and maintained online as the single authoritative source of soi
