Students study the diversity of marine life and their habitats.  In this aquatic ecosystems lesson plan students complete a lab activity and experiment. 
Ninth graders record information on aquatic ecosystems and create a labeled diagram of an ecosystem of their choice. They can choose from an ocean zone, estuary, river, lakes, or beaches. The student has to explain their biome of choice.
Students conduct an experiment using a small sample from a local water source. They introduce fertilizers and pesticides, separately, and carefully examine the results in their simulated aquatic ecosystem.
Students study ponds and wetland ecosystems and examine the food chains and webs in them.  In this aquatic ecosystems lesson plan students answer questions about the diversity of the flora and fauna in a pond. 
Students visit a local stream, pond, creek, or river and collect macroinvertebrates. They sort macroinvertebrates and identify each species using a dichotomous key. Students decide on trophic levels and construct a possible food web for their ecosystem.
Demonstrate to your middle school science learners how chalk breaks down in a weak acid. Discuss what affects acidic rain might have on ecosystems. Lab groups then choose one of two questions: "How does acid precipitation affect an aquatic ecosystem?" or "How does acid precipitation affect terrestrial ecosystems?" They work together to design and perform an experiment to answer their question. This is a stellar lesson on acid rain, and it reinforces practice of lab skills and the scientific process.
Tenth graders research two ways to test the water quality near their home. In this chemistry lesson, 10th graders determine the short and long term effect of different substances on aquatic ecosystems. They conduct tests and write a conclusion based on experimental results.
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 data while making observations.
Young scholars study the intertidal habitat, tidal pools and the organisms that live in them.  In this aquatic ecosystems lesson students take a field trip and experience first hand the local seashore environment. 
Young scholars explore populations of ecosystems.  For this middle school science/math lesson, students observe an aquatic ecosystem over a four to six week period, collecting data on temperature and pH values as well as qualitative observations.  Young scholars explore the effect of changes in pH and temperature on the ecosystems. 
Students explain why dissolved oxygen is important in aquatic ecosystems. They evaluate the optimal dissolved oxygen levels for living organisms.
Learners measure the toxic levels of runoff and discuss the effects it would have on the aquatic system. In this runoff lesson plan, students answer questions to how runoff would affect the animals in an aquatic system.
Students evaluate the relationship between oxygen levels and the amount of organic matter in an aquatic ecosystem. They explain the relationship between oxygen levels, bacteria and the breakdown of organic matter using an indicator solution.
Give your environmental or life science class a splash of aquatic ecosystems information using this presentation. The ten slides introduce viewers to aquatic ecosystems and three prominent microorganisms: hydras, rotifers, and crustaceans. Photos of microorganisms are included, but the rest of the slides simply consist of bullet point information. 
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 they move from the producers through the different levels of consumers. A clear demonstration of the widespread, negative effects of pollution and the impact it has on the food we eat. Reinforce these concepts with a reading of The Mysterious Marching Vegetables, connecting science and children's literature.
Young environmentalists examine the biogeochemical cycles: carbon, nitrogen, phosphorous, and water. Explanatory notes and colorful diagrams are presented for each, followed by a blank diagram that is filled in click-by-click as a reinforcement. After teaching the cycles, time is spent on limiting nutrients and eutrophication in aquatic ecosystems. This commendable PowerPoint will educate and arrest the attention of your high schoolers.
Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have performed in previous sessions. It includes links to those lessons as well as to many other resources. This particular resource would be a poignant conclusion to an ecology unit.
Students have the opportunity to view two types of algae under 400x magnification with a compound microscope. They make observations and record their observations through drawings and words. In addition, they identify different qualities such as cell structure, movement and other qualities of different types of algae.
Here is a complete activity in which young biologists or ecologists test the pH, dissolved oxygen, turbidity and temperature of stream water. The class visits an actual stream and makes observations of the site. They use scientific equipment to measure properties of the water. The authors provide detailed steps, graphs, and extension activities. Although intended to last for two 45 minute class periods, a week could be spent analyzing and presenting results.
Young scholars investigate beaver adaptations, life cycle, and the effects of beaver behavior on ecosystems. They compare and contrast how beavers influence the ecology of both forest and aquatic ecosystems.
