Bio Build-up
Trace pollutants through the environment in the seventh lesson of this series on the science of food. Looking at a picture of the plants and animals in an aquatic ecosystem, learners use dot stickers to represent harmful chemicals as...
Curated OER
Water and Land Ecosystems
Students investigate the differences between a land and aquatic ecosystem. They use the information in order to present it in an assessment. There are target questions that can be used to guide research, lead a classroom discussion, or...
Curated OER
Biomanipulation
Young scholars explore the effects of aquatic trophic relationships on water transparency. They observe and explain the effects of reducing nutrient inputs on agal density on water transparency.

"Using Cichlids To Demonstrate the Effects of Human Activity On Ecosystems"
Students explore the freshwater ecosystem of Africa's Lake Victoria by creating a freshwater aquarium. They investigate factors affecting the aquarium's ecosystem and conduct lab activities.
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.

Forest In A Jar
Students conduct an experiment using soil, water, seeds, a plant, and a jar; and then draw a poster to represent their observations and findings. They make a poster showing what happened to their aquatic environment.
Curated OER
Point- vs. Non-point Pollution
Students differentiate between point and non-point pollution and determine how the different types of pollution are harmful to aquatic ecosystems. They complete a series of tests on a sample of "polluted" water and a sample of "pure" water.
Curated OER
Graphing Aquatic Insects
Students identify aquatic insects. In this organism instructional activity, students locate aquatic insects near a local waterway and collect them. Students graph the amount of insects that they collected.
Curated OER
Photosynthesis and Respiration
Students comprehend the relationship between plants and animals in an aquatic ecosystem. They predict the effects of low dissolved oxygen on the organisms. Students create microcosms with plants, animals, or both. They determine which...
Curated OER
Forest In A Jar
Tenth graders are introduced to the process of succession and gain awareness of the changing nature of ecosystems. They demonstrate a comprehension of the dynamic nature of ecosystems, including the relationship between ecological...
Curated OER
Does Clear Water mean Healthy Water?
Learners test their local aquatic site to determine its water clarity. They collect a water sample and measure its turbidity using a sensor, then they repeat the experiment to obtain a second turbidity reading to find the average value.
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...
Curated OER
environment: Fresh and Saltwater Habitats
Students compare and contrast fresh and salt water coastal environments. After describing how sea animals adapt to their habitats, they design a variety of sea creatures and explain how the adaptations aid in the animals' survival. ...

Visual Vocabulary
Students interpret and name the vocabulary termed acted out by the mime. In this science/language arts/physical education activity, students are given a set of vocabulary terms to discuss within their group. Next, students place all...
Curated OER
What If There's No Light?
students discuss the importance of light and the consequences of living without it. Using a plant as a demonstration, students predict and observe what happens to a plant when it does not receive enough light. In groups, they experiment...
Curated OER
Oceans in Motion
This simple activity introduces children to basic marine life as well as to show them the necessity of protecting aquatic environments. Some famous marine life animals are introduced via vocabulary words, then children cut out pictures...
Curated OER
The Wonderful World of Slugs
Examine a slug? Of course, what else would a 2nd grader do with it? Pupils use clues and go on a slug hunt, read a slug story, or make a cooperative group mural of a slug's habitat. While older learners catalog slugs, go on a slug hunt,...
Curated OER
Ecosystem Damage from Household Cleaners
Third graders assess the damage done to various ecosystems by cleaning products and discover how scientists test water quality. Using stream water and common household cleaning agents, they work in groups to test for pH levels. Once...
Curated OER
Hypoxia and the Dead Zone in the Gulf of Mexico
Students investigate the causes of hypoxia, the characteristics of a watershed, and how the actions and management practices of people can both negatively and positively affect aquatic ecosystems.
Curated OER
Marine & Aquatic Habitats Activities - Marine Ecology
Middle schoolers enact the life cycle of a sessile animal and quantify the possibility of survival under the conditions given. They then present to the class a new adaptation which will increase the animals chance of survival.
Curated OER
Ecology and the Conservation of Natural Resources
Students examine the components of ecosystems. They compare and contrast an ecosystem to an aquatic ecosystem. They examine a local ecosystem and discuss its components.
Curated OER
What Is In The Water?
Students investigate the biotic and abiotic factors that are found in an aquatic ecosystem. The emphasis is upon the investigation of present an projections of future water quality. Then students visit a local body of water to gather...
Curated OER
That Is Predictable
Students investigate the changes that can take place in an aquatic environment. They conduct research using a variety of resources. The research is used to report different possibilities of change because of abiotic or biotic factors.
