Energy Flow Through Ecosystems Summary:The objective of this lesson plan is to give students a basic understanding of how energy flows through an ecosystem by introducing them to the concepts of food chains and energy pyramids. Included in this lesson are two small group activities and a power point presentation. The power point presentation provides the students with fundamental knowledge about one way that organisms in an ecosystem interact and depend on one another. By using the power point lecture, the students are able to visualize food chains and energy pyramids. Main Curriculum Tie: Science - BiologyStandard 1 Objective 1Summarize how energy flows through an ecosystem.

The Nitrogen Cycle Game | UCAR Center for Science Education The Nitrogen Cycle Nitrogen is an element that is found in living things like plants and animals, dead things like fallen leaves and dear animals, and non-living things like air and water. The nitrogen cycle is one of the biogeochemical cycles and is very important for ecosystems. Nitrogen cycles slowly, stored in reservoirs such as the atmosphere, living organisms, soils, and oceans along its way. Most of the nitrogen on Earth is in the atmosphere. Approximately 80% of the molecules in Earth’s atmosphere are made of two nitrogen atoms bonded together. Certain actions of humans are causing changes to the nitrogen cycle and the amount of nitrogen that is stored in reservoirs.
Climate change: Rising sea levels hit Maputo, Rotterdam When people talk about the impact of rising sea levels, they often think of small island states that risk being submerged if global warming continues unchecked. But it's not only those on low-lying islands who are in danger. Millions of people live by the sea - and are dependent on it for their livelihoods - and many of the world's largest cities are on the coast. By 2050 the number of people living in delta cities is set to increase by as much as 70%, experts suggest, vastly increasing the number of those at risk. To shed light the impact of rising sea levels, we are taking a close look at two very different cities, Rotterdam and Maputo , and their varying responses to the problem. Much of Rotterdam - Europe's busiest port city - lies several metres below sea level, and this vulnerable position has led it to develop some of the best flood protection in the world. Weaker Gulf Stream Off the Netherlands, for example, sea levels rose by some 20cm in the last 100 years. "We need to invest.
Global Warming Explained, In About A Minute : 13.7: Cosmos And Culture Jean-Pierre Clatot/AFP/Getty Images On a pleasant day in 2011, researchers roamed San Diego's public parks in search of volunteers to fill out anonymous surveys about global warming. In the end about 270 responses were collected from a mix of park visitors and nearby community college students. The researchers wanted to know how well the average American understands the basic processes responsible for global warming, and whether there's a relationship between this basic understanding and the belief that global warming is actually occurring. The results were sobering. The solution to this puzzle comes from an important asymmetry: the sunlight that hits the Earth's surface is largely visible light, and that light is returned from Earth's surface as infrared light. Michael Ranney, the lead author on the study, offers this 35-word explanation: Earth transforms sunlight's visible light energy into infrared light energy, which leaves Earth slowly because it is absorbed by greenhouse gases.
