Curated OER
Go With the Energy Flow
Students explore energy and nutrient flow. In this science instructional activity, students diagram the flow of energy through food chains and food webs. Students discuss the importance of energy flow in Earth's ecosystems.

Comparison of Different Methods for Determining Stream Flow at a Stream Site
Students make measurements and calculations to determine the stream flow of an outdoor stream site. In this stream characteristics lesson, students travel to a field site to construct a transect across a stream and measure the...
Curated OER
Nutrients In Chesapeake Bay
Students perform pH and turbidity test to determine water quality. In this environmental science lesson, students analyze NASA database on chlorophyll-a in the bay. They explain how a small river area affects Chesapeake Bay.
Curated OER
Chemistry in Soil-Plant Relationship
Students apply the science of chemistry to soil and plant relationships. They define diffusion and indicate for which of these nutrient(s) would you expect diffusion to be the most important for movement to the plant root? Pupils...
Curated OER
Highways of Life
Students explore the circulatory system. They participate in media activities to explore blood flow and identify the parts of the circulatory sytem. Students create a model of the circulatory system.
Lake Science Collaborative
Blood Circulation Simulation
Act out the circulation of blood in the body with an innovative activity. Kids act as either body parts or blood, and carry necessary nutrients and waste throughout different stations to represent the way that oxygen circulates.
Curated OER
Blood Moving from Heart Around Body Simulation
Pupils review circulation and blood flow patterns from different parts of the body. They play a game using colored yarn and index cards to simulate blood flow, oxygenated blood, arteries and veins.

Dirty Decomposers
Do not let the class just sit and rot. Pupils learn how decomposition and nutrient recycling is important to an ecosystem. Groups design an experiment to determine how environmental conditions affect decomposition. They develop a poster...
May Media Group
Treatment Plants
Young scientists explore nature's water treatment plants in this simple science demonstration. By placing a stalk of celery in a cup of water mixed with food coloring, children are able to observe how plants absorb nutrients and...
Curated OER
Toward a Sustainable Agriculture
Young scholars examine how to use ecological analysis to animal production systems. In this sustainable agriculture lesson students examine where the nutrients flow in a system and complete several activities.
Curated OER
Ocean Currents
Students label the names, relative temperature, distribution, and direction of flow of major ocean currents on a world map. They also explore and model the natural forces that affect the movement of ocean currents through demonstrations...
Curated OER
Horticulture Crops in the agro-ecosystem
Ninth graders apply ecological analysis to fruit and vegetable production systems. In this horticulture activity students learn about different management practices.
Curated OER
The Nutrients Public Transportation System
Students investigate the human circulatory system by experimenting with hoses. In this human body lesson, students create a system of hoses simulating the circulatory system which they utilize to pass objects through....
Curated OER
Runoff: Intro to Watersheds
Students are taught that a watershed is, what types of basic land cover are impermeable and permeable to water. They trace the flow of water around their school and around their home. Students determine what watershed their school is a...
Cornell University
Bacteria Take Over and Down
Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...
Texas Heart Institute
Anatomy: How Does the Cardiovascular System Work?
How can the circulatory system compare to a city map? Pupils distinguish the "roadways" and "vehicles" of the cardiovascular system, compare the anatomy and function of veins and arteries, and review different types of blood cells with...
Curated OER
Reduced Fare
Students discover the relationship between tectonic plate boundaries and the communities of life that thrive at such boundaries. In this biology lesson, students find that methane from oxidized carbon in sediments provides nutrients for...
Curated OER
Science Excursion: Cover Mapping Land
Students study remotely sensed images and topographic maps to classify land cover types in their watershed area. They take samples in the watershed area to interpret the images.
Curated OER
Populations and Ecosystems
Seventh graders create a model of an ecosystem and label it to show structure and function. They research the food web of an aquatic animal and also trace energy flow from the primary producer up the food chain.
Curated OER
Water Ecology Lab
Students determine the characteristics of a stream ecosystem and its organisms. In this water ecology lesson students complete several labs that shows them presence of life, water appearance, and water flow.
Curated OER
Biochemical Cycles: Recycling Carbon and Nitrogen
Students construct flow diagrams of the carbon and nitrogen cycle processes. They identify sequences in each cycle that are affected by human impact and present their research to the class.
Curated OER
Food Webs
Students research rainforest animals and use that information to make a flow chart to show the order in which energy is transferred through several organisms. They label the producers, consumers, and decomposers in their chart.
Curated OER
Marine Food Webs
Learners examine how food webs illustrate the ways in which organisms depend on each other for energy and nutrients, and make food webs showing the feeding relationships among organisms encountered in the Gal??pagos coastal waters.
Curated OER
Immersion Presents Monterey Bay
Students study Monterey Bay. For this Monterey Bay lesson, students create a model of upwelling around Monterey Bay. Students simulate surface water movement relative to prevailing winds.
