KILL 'EM ALL They buzz. They bite. And they have killed more people than cancer, war, or heart disease. Ever since there have been humans, mosquitoes have been biting us, and we’ve been trying to kill them. Oh, and we visit a mosquito factory in eastern Brazil. And after listening, read this, from Radiolab producer Andy Mills: what if we don't kill 'em all? Special thanks to reporter David Baker The Population Biology of Isle Royale Wolves and Moose: An Overview | The Wolves and Moose of Isle Royale 1. Five decades of wolf-moose dynamics The wolves and moose of Isle Royale have been studied for more than five decades. The most important events in the chronology have been essentially unpredictable. 2. Each symbol on this graph represents the density of moose (read from the horizontal axis) and the density of wolves (read from the vertical axis) for a particular year. Wolf and moose densities are the total number of wolves and moose on Isle Royale, divided by the size of Isle Royale, 544km2. This graph tells a great deal about how wolf and moose populations are interconnected. By contrast, if moose abundance was determined primarily by wolf predation, and if wolf abundance was a good indication of predation pressure, then wolf and moose abundance would be negatively related. This graph shows that wolf and moose abundances are neither positively nor negatively related. 3. The most remarkable observation is just how variable kill rate is. 4. 5. 6. So how is it on Isle Royale? 7. 8. 9.
WolfQuest Using the Carbon Cycle Interactive Game in the Classroom - Windows to the Universe Have students read the Windows to the Universe page entitled The Carbon Cycle. Introduction: Ask students to (based of the reading) list the places where carbon is found on Earth. As a class, brainstorm why carbon is important and why carbon is sometimes hazardous. Tell students that for this online interactive game, they are all playing the role of carbon atoms. They will travel through the carbon cycle. Students write a paragraph about their trip through the carbon cycle. Carbon is the 12th element in the periodic table. The carbon cycle is one of the biogeochemical cycles. The six locations along the online game board "map" (atmosphere, plants, soils, shallow ocean, deep ocean, and marine life) are called carbon reservoirs or carbon pools. In this interactive game, students assume the identify of carbon atoms that are released into the atmosphere when fossil fuels are burned.
Population Issues & Facts - Population Connection When Population Connection was founded as Zero Population Growth, or ZPG, in 1968, there were 3.5 billion people on the planet. Since then, our world population has doubled – with no end in sight. The United Nations projects that world population will reach 9.6 billion by 2050, and nearly 11 billion by 2100. Why does it matter? One in eight people is hungry. As America's largest grassroots population organization, we focus on the connections between population and three main issue areas: Click play below to watch our famous "dot" video, tracking world population growth since 1 AD.
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. It is hoped that through the small group activities, the students will help each other gain a better understanding of how energy flows through an ecosystem. Main Curriculum Tie: Science - BiologyStandard 1 Objective 1Summarize how energy flows through an ecosystem.

Ecology Disrupted Using real scientific data to link daily life to environmental issues and ecological functions in secondary school science classrooms. These case study units engage students in real scientific research that has been published in peer-reviewed scientific journals. The research is introduced through the use of videos produced by the Museum's Science Bulletins program. The overarching goals of these units are to: Connect regular daily life activities to disruption of ecological function Analyze authentic scientific data Learn about real scientists and their stories Before you begin... Read Why Use Ecology Disrupted? Review How to Use the Ecology Disrupted Materials to learn how to navigate the Ecology Disrupted web site, and how to locate and use specific materials for creating your own lesson plans. As you use Ecology Disrupted... Each unit has an index that lists unit contents by topic and by type of material.

SmartGraphs | Concord Consortium In the fall of 2011, SmartGraphs conducted a randomized experimental trial in 29 Pennsylvania schools. In 14 schools, 17 experimental teachers used SmartGraphs activities with 49 8th and 9th grade Physical Science classes studying the motion of objects (such as position-time and velocity-time graphs). In the other 15 schools, 18 control teachers taught the same topic using the same textbooks, with 42 Physical Science classes. The first research question was: What do teachers using SmartGraphs physical science activities believe about the software, including how well the software matches important learning goals for the motion unit of study? The second research question was: Do students who use SmartGraphs activities learn more than comparison students studying the same topic from the same textbooks, but who do not use SmartGraphs activities? Gain Scores from Pre to Post Test Answers to both research questions were positive, which is encouraging.
