Cleaning Up with Decomposers

(Complete Item Description)

Abstract:: Students investigate decomposers and the role of decomposers in maintaining the flow of nutrients in an environment. Students also learn how engineers use decomposers to help clean up wastes in a process known as bioremediation. This lesson concludes 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.

Got Energy? Spinning a Food Web

(Complete Item Description)

Abstract:: Students learn about energy flow in food webs, including the roles of the sun, producers, consumers and decomposers in the energy cycle. They model a food web and create diagrams of food webs using their own drawings and/or images from nature or wildlife magazines. Students investigate the links between the sun, plants and animals, building their understanding of the web of nutrient dependency and energy transfer.

Go with the Energy Flow

(Complete Item Description)

Abstract:: 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.

NASA KSNN What is protein?

(Complete Item Description)

Abstract:: Nutrients (raw materials) are chemical substances found in foods. Essential nutrients are those that the body cannot make or is unable to make in the amount it needs. The 50 or so essential nutrients people need can be grouped into 6 basic categories and include protein, carbohydrates, fat, vitamins, minerals, and water.
