NASA KSNN Where can NASA find water on Mars?
Find out more about NASA's hunt for water on Mars and analyze soil and frozen soil samples.
NASA KSNN What do animals need to live?
There are many different habitats on the Earth. These vary in the landforms, sources of water, and climate conditions. Plants and animals are specially adapted to live in their habitats. Animals suited to live in the desert (very dry, either hot or cold) would have a difficult time living in the tropical rain forest (warm and very wet). Grades K-2

Irrigation Conveyance & Control Systems
This is a course regarding measurement of flow rates and water levels. Calibration, design, and selection of open-channel flow measurement structures. Design of irrigation conveyance and distribution system infrastructure.
Sprinkle & Trickle Irrigation
This is a course regarding technical design and evaluation of pressurized agricultural irrigation systems, including system layout, pipe sizing, water applicator selection, pumping system hydraulics, water filtration requirements, and water application uniformity and efficiency.
Where Deserts Form
Most of Earth's deserts can be found in dry areas created by global circulation patterns. The deserts of our world are not restricted by latitude, longitude, or elevation. This site, produced by the U.S. Geological Survey, uses text and pictures to describe how atmospheric circulation patterns influence the locations of deserts on Earth and possibly on other terrestrial planets as well.
Landmark larynx transplant
Brenda Jensen is now able to speak for the first time in 11 years, thanks to a groundbreaking larynx and trachea transplant carried out by a joint team of surgeons from UCL and UC Davis. Techniques of the procedure, particularly the repairing of muscles and nerves in the neck, had been developed by Professor Martin Birchall (UCL Ear Institute).

Earth's Water: Groundwater
This is part of the U.S. Geologic Survey's Water Science for Schools website. It consists of a set of links to other parts of the site dealing with groundwater-related topics such as groundwater flow and distribution, trends in groundwater use, importance of groundwater, and groundwater quality. Graphic illustrations and photographs are provided.
The Dose Makes the Poison -- Or Does It?
News reports frequently include stories about toxic chemicals in our food, water, and environment. But what does it mean to label a substance either "toxic" or "nontoxic"?
Toxicity indicates the degree to which a substance is poisonous to biological organisms, including humans. The traditional way to test toxicity is to count how many laboratory organisms die or suffer impaired health when exposed to various concentrations of a substance. However, in recent years this method of estimating the d
Water Basics
Looking at water, you might think that it's the most simple thing around. Pure water is colorless, odorless, and tasteless. But it's not at all simple and plain and it is vital for all life on Earth. Where there is water there is life, and where water is scarce, life has to struggle or just "throw in the towel."
So what is it about water that makes it so important to us? And what is it about water that makes it water? This section of Water Science for Schools explores the physical and chemical
Social movements and global justice
In this podcast we hear about an international conference which brings together academics and social movement activists from around the world.
The conference is hosted by the Centre for the Study of Social and Global Justice, in the School of Politics and International Relations.

Cloud Dreamer
In pretending, we learn to navigate with ease between real and imaginary worlds while learning the differences between them. Using our imaginations encourages original thinking, flexibility, adaptability, empathy, and the ability to generate multiple solutions to a problem. Pretend play helps us learn to think visually and spatially and to both capture and express ideas.
Microwaves

Greenhouse Effect, Climate Change, Global Warming
The terms greenhouse effect, climate change, and global warming are often used interchangeably, yet they really refer to three separate and distinct processes. This activity examines all three and assesses whether Earth's atmosphere is getting warmer.
