Students, in groups, create a slide show about the ecosystem and answer critical thinking questions based on their research.

Students examine forest food chains and create a forest habitat in the classroom. They are introduced to the concept of interdependence in Nature. They define a simple forest food chain and develop inquiry process skills.

Students identify the types of pests and categorize them. They identify their food chain and create a poster showing the food chain for the pests.

Learners identify the main parts of a coral reef. They describe a coral reef food chain.

Eighth graders design posters of working ecosystems using pictures from magazines. They label autotrophic, heterotropic, or saprotrophic energy sources, and identify predators and prey.

Students explain the different stages in the growth of a frog, then analyze and collect data to make generalizations about a larger population. They determine the survival rate of a population of tadpoles under controlled conditions.

Fifth graders observe their plant experiments that they started in a previous instructional activity and examine the role of decomposers in the nitrogen cycle. Two weeks after they set up a worm terrarium, they analyze any changes they...

Fourth graders investigate ecosystems. In this ecosystem lesson, 4th graders explore producers, consumers, and decomposers and study the interdependence of each.

Fourth graders distinguish between acquatic and terrestrial organisms. They label animals as producers, consumers, and/or decomposers.

Fourth graders create an ecosystem as a class. They have already produced smaller ones. They use a pond or something similar on school grounds to meet the needs of certain plants and animals of their ecosystem. Specifically created will...

Students explore DNA structure using materials such as Twizzlers, small colored gumdrops and/or toothpicks.

Students research and report on the ocean's problems of disappearing or diminishing species around the world. students examine ecosystems and food chains and present their findings to a mock panel of science experts.

Students closely observe the natural world, record data, and notice patterns as the seasons unfold, they build a deeper understanding of seasonal change! The definition of phonology is the focus of this lesson and how it changes...

Learners explore the cycles of an ecosystem.  In this environmental science lesson, students work in groups to research the nitrogen cycle, the water cycle, or the oxygen-carbon dioxide cycle. Learners prepare a PowerPoint or other...

Fourth graders observe brine shrimp over several days. They create drawings showing the growth and development of the shrimp. They research web sites to find out where brine shrimp fit on the food chain and what makes the shrimp unique.

Students research various birds of prey on internet by following a worksheet with specific questions. Students answer questions on worksheet and write short response after completing research.

Students study the gray whale migration and compare their populations to the increasing ocean temperature.  For this whale watcher lesson students draw a food chain.

Students explore the physical characteristics, distribution and habitat of termites. The lesson focuses on the termite as a social creature contrary to most other insects.

Students complete a unit of lessons on animals and animal conservation. They observe a square meter of ground outside the school, set up a model environment, analyze an owl pellet, grow bread mold, and explore various websites.

Students participate in a virtual field trip to Lake Superior. In groups, they perform experiments in which test the level of toxins and bacteria in the water. They also watch video segments life in the lake and discuss their observations.

The students will be given approximately five minutes to individually brainstorm general plant and animals adaptations that they already know about. The class will use these as a starting point to develop a KWL chart specific to desert...

Fifth graders relate population of animals to its available food supply. They participate in an experiment and gather information. They use the data to draw conclusions.

Third graders identify features of producers, herbivores and carnivores. They discuss the features that aid in survival for those animals. They organize animals into categories to complete the lesson.

Third graders research ecosystems, the work of ecologists, John Muir's contribution to the environment and an endangered species of their choice. They read books, participate in discussions, and write reports.
