Ecosystem In A Bottle
Ecosystem activities show how everyone and everything is interconnected. The smallest change can make a big impact.
Howard Hughes Medical Institute
Modeling Trophic Cascades
In the ecological game of who eats who, one small change can have a big impact! Individuals create food chains in an array of ecosystems, then determine what happens to organisms in the chain when one organism changes its feeding...
Curated OER
Aquatic Ecosystems
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.
Curated OER
Aquatic Life
Students explore aquatic life. In this science instructional activity, students visit an aquatic ecosystem and collect animals found there. Students create a food chain for the aquatic ecosystem.
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
Ecosystems of the World
Students are able to list different ecosystems and describe their environment and organisms. They have an understanding about the function and balance of the ecosystems. Students are able to tell what type of ecosystem the St. Mary's...
Curated OER
Lentic Ecosystem or Lotic Ecosystem
Students explore the differences between lentic and lotic ecosystems. For this ecology lesson students study the water systems in Pennsylvania.
Curated OER
Ecosystems: What Are They and How Do They Work?
Students explore the characteristics of major ecosystems, the interactions of the organisms within the systems, and the effects of humans on the system. Both living and non-living components are examined in this five lesson unit.

Habitats
The circle of life is all around us, from the black bears in the nearby mountains to the pile of dead leaves in the backyard. Encourage young scientists to take a critical look at the world around them with a set of lessons about natural...
Curated OER
The Effects of Agricultural Fertilizer Runoff Upon Aquatic Ecosystems
Students 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.
Curated OER
Water Cycle and Ecosystems
Young scholars explore the water cycle. In this investigative lesson, students examine the water cycle process. They will record their observations and discuss marine and freshwater ecosystems.
Curated OER
Speedy Succession
Fifth graders identify how a pond can change into a grassland. An ecosystems lesson where learners identify pioneer and climax species, and recognize that ecological succession can take up to 100 years or more. Some excellent activities...
Curated OER
Visual Vocabulary
Students interpret and name the vocabulary termed acted out by the mime. In this science/language arts/physical education lesson, students are given a set of vocabulary terms to discuss within their group. Next, students place all...
Curated OER
Examining the Stages in Ecological Succession
For this ecosystems worksheet, students use illustrations and descriptions of four ponds to determine the order of succession. Students complete 8 fill in the blank questions and 5 short answer questions.
Curated OER
Biomanipulation
Students 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.
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
Personal Ecosystem
Young scholars build an aquatic ecosystem using large glass pickle jars. In this ecology lesson, students build and ecosystem then observe and collect data on the habitats. In this long term project young scholars observe a population...
Curated OER
Wetlands Field Trip
Seventh graders used aquatic nets and other equipment to sample organisms in the lake -made plaster casts of footprints found around the edges of the lake -used reference materials to identify all organisms collected -filled out an...
Curated OER
Marine & Aquatic Habitats Activities - Terrestrial Forests vs. Kelp Forests
Students discuss concept and specificity of habitats, both marine and terrestrial, list similarities and differences in the habitats of a kelp forest and a terrestrial forest, compare types of organisms that occupy corresponding types of...
Curated OER
Micro-Ecosystems
Students create a sustainable, self-contained ecosystem in a ten-gallon aquarium.
Curated OER
Upsetting Ecosystem Balance
In this ecosystem worksheet, students determine the affect on an ecosystem if different organisms are altered or removed. Students complete a graphic organizer.
Curated OER
"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.
