Using GLOBE Data to Analyze Land Cover
The purpose of the resource is to develop hypotheses about which environmental factors are most important to plants.
Photosynthesis and Respiration
Most people are aware that plants undergo photosynthesis, a process by which they convert sunlight and carbon dioxide in sugar and water. But not as many realize that plants also undergo respiration, which is the reverse of this process.
Total Ozone Emission
In this activity, students will analyze their nitrogen oxide emissions from all sources (including coal-fired power plants, natural gas combustion, gas-powered lawnmowers, etc.).
Home Chemicals
This lesson provides an introduction to the occurrence and possible risks of household chemical products. Topics include some basic chemistry (how elements combine to form compounds) and how chemicals are classified.
Drinking water treatment 2
This course deals with the design of drinking water treatment plants. We discuss theory and design exercises.
NASA KSNN What do plants need to grow?
By definition, a plant is a living thing that produces its own food through photosynthesis. This process uses carbon dioxide and water. Trapping light from the Sun, plants are able to change sunlight's energy into useable chemical energy. Not only is chemical energy produced, but oxygen is a by-product of photosynthesis. Plants are essential to the balance of life on Earth - and to life, as we know it, on other planets.
This Land is Our Land
Throughout history, as the concepts of empire and nation-states took hold, individual countries secured their borders and tried to keep unwanted migrants out. As we enter the 21st century Anwarul K.

The Fog of Games: Legacy, Land Grabs and Liberty. Reporting the London Olympics
The Olympics are brief and transitory television events that disguise and justify mega projects of vast urban restructuring that permanently distort our cities for the benefit of a few business interests. The common features of these mega projects are unprecedented land grabs, the peddling of myths of 'regeneration' and 'legacy' benefits, the sweeping away of democratic structures and planning restraints, the transfer of public money into private hands, and 'information management' to hide truth
Junior Solar Sprint and Hydrogen Fuel Cell Car Competitions
The National Renewable Energy Laboratory hosts the U.S. Department of Energy's Junior Solar Sprint/Hydrogen Fuel Cell (JSS/HFC) Car Competitions. Middle School teams from all over the Colorado Region participate in this fun, educational and exciting event. Teams work together building solar and/or hydrogen fuel cell cars with guidance from a parent or teacher coach to compete in race and design categories. A "Spirit Award" is also presented to the team recognized for good sportsmanship. Building
How to Draw a Cartoon Car

Cell Division in Animals
This is a brief computer-animated video that describes differentiation in animals at the cellular level (cell division). Once the cells are differentiated they lose the ability to divide. As a result, one cannot grow a whole animal in a culture medium from a single cell. The growth of the whole animal in a single cell is only possible in the early stages of development - after the first one or two divisions. Other key words include: ectoderm, mesoderm, and endoderm.  Run time 01:51.
