Students explore the biosphere and its associated environments and ecosystems in the context of creating a model ecosystem, learning along the way about the animals and resources. Students investigate different types of ecosystems, learn new vocabulary, and consider why a solid understanding of one's environment and the interdependence of an ecosystem can inform the choices we make and the way we engineer our communities. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

Students learn about energy and nutrient flow in various biosphere climates and environments. They learn about herbivores, carnivores, omnivores, food chains and food webs, seeing the interdependence between producers, consumers and decomposers. Students are introduced to the roles of the hydrologic (water), carbon, and nitrogen cycles in sustaining the worlds' ecosystems so living organisms survive. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

This article highlights lessons that help K-grade 5 students understand that animals and plants can only survive in certain environments.The lessons support the theme of an issue of the free online magazine Beyond Weather and the Water Cycle. The theme is "We Depend on Earth's Climate."

As students learn about the creation of biodomes, they are introduced to the steps of the engineering design process, including guidelines for brainstorming. Students learn how engineers are involved in the design and construction of biodomes and use brainstorming to come up with ideas for possible biodome designs. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

Students learn about population density within environments and ecosystems. They determine the density of a population and think about why population density and distribution information is useful to engineers for city planning and design as well as for resource allocation.

Energy is neither created nor destroyed - and yet the global demand for it continues to increase. But where does energy come from, and where does it go? This video examines the many ways in which energy cycles through our planet, from the sun to our food chain to electricity and beyond. [4:44]
