That’s An Otter Story
Young scientists discover how sea otters' habitats have changed due to human impact. Through conversation, video observation, and story reading, scholars identify how human interactions change a specific ecosystem in both positive and...

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
Trophic Relationships, Cycling of Chemicals, Human Impact on Ecosystems and Conservation
Students explore how the energy flow through a system is related to trophic levels. They investigate how organisms affect the cycling of elements and water through the biosphere. Students participate in lab activities to observe ways...
Curated OER
Ecosystem Energizers
Fourth graders see how the flow of energy through an ecosystem made up of producers, consumers, and decomposers carries out the processes of life and that some energy dissipates as heat and is not recycled.
Curated OER
Working for Water
Learners examine the ways that government works to help improve aquatic habitats. In this water habitats activity students view a video and plan a school restoration project.
Curated OER
Ecosystems
Students work in small groups to create a poster illustrating the flow of energy through a typical ecosystem, then present their posters to the class.

The Flow of Energy Through a Food Chain
In this food chain worksheet, students write in the steps that show how energy flows through a food chain, from producers to consumers. This worksheet is a graphic organizer.

The Biogeochemical Cycles
The majority of this presentation is a collection of diagrams and graphs that back your lecture on biogeochemical cycles. The last few slides define ecosystems and the Gaia hypothesis. You may find these slides valuable, but will...

Freshwater Food Chains
What's in the water? Encourage your class to further explore this question and learn about pond ecosystems, food chains, and food webs as they complete this hands-on activity. They view the environment from a new perspective after...

Energy Flow Through an Ecosystem: Food Chains, Food Webs, and Energy Pyramids
When a minnow eats a piece of plastic, that garbage often tracks through multiple animals, causing harm to each as it passes through the food chain. Scholars learn about food chains, food webs, and energy pyramids with a presentation. It...
Curated OER
Heat 1
In this heat worksheet, learners determine the heat gained or lost when matter changes phases. Students review the energy flow through ecosystems by comparing trophic levels and food webs. This worksheet has 10 fill in the blank, 5 short...
Curated OER
Watershed Tourist
Learners recognize and categorize different bodies of water. In this watershed and water environments lesson, students "Follow the Water from Brook to Ocean." Learners define the different bodies of water and sort from smallest to...
Curated OER
Mini-Ponds
In this mini pond worksheet, students create a mini-pond ecosystem with soil, water, and plant life. Students let their ecosystem sit for a day and they observe a sample the next day. Students identify all the pond water microorganisms...
Curated OER
Water Contamination Mapping Lab
Students are introduced briefly to the Biscayne Bay Ecosystem, observed microbe distributions and water current maps are introduced. They measure water current speeds to predict the movement of pollutants based on the type of the tidal...
Curated OER
Floods: Rising Waters and You
Students examine the relationship between human-made structures, flood waters and the increasing population through video clips, websites and a lab experiment.
Curated OER
The Mighty Hudson Stretches its Mussels
Students brainstorm possible causes of zebra mussel migration and population expansion. They identify the key causes and effects of the disturbance of the Hudson River ecosystem and research causes and effects in the disturbances of...

Visualizing Succession
Ecosystem change is easier to understand when you use hands-on activities.
Curated OER
What makes up YOUR Environment!
Middle schoolers create their own land or water environment. They make their environment livable for all the different animals they collect to put in it. Students research the types of animals that they can have in their environment,...

Where Oh Where Did the Rainwater Go?
Third graders conduct an experiment to determine how water moves through different soils found in the Apalachicola River watershed. They read a scenario, conduct the experiment, answer follow-up questions, and draw the water movement...

Are You Concentrating?
Explore the importance of a concentration gradient in the rates of dissolution. Using the ocean ecosystem, learners study rates of dissolution around coral reefs. A hands-on experiment helps individuals discover the effects of changing a...

The Value of Oregon’s Forests
No matter where you go, you're in the middle of a forest in some way. Use a lesson about forests and the many ways they contribute to our world, including the ecosystems of animals and plants living in their shady soil.
Curated OER
Pond Ecology
A lab activity is a great way to incite thoughtful questioning and scientific processes. Pupils will collect organisms with a Petri dish, make observations, sketch the organism, ask questions, then attempt to identify the specimen...

LEAF (Learning Exercises and Activities in the Forest
Students observe populations and determine the functions (e.g., decomposers, producers, consumers) they serve in an ecosystem. They investigate the energy flow ecosystems. Students investigate factors (.g., Resources, light, water) that...
