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.

For this biology worksheet, students identify and define the vocabulary terms listed and make a prediction about the outcomes of the experiment. Then they complete the chart of the observations of the plankton diversity in drops of pond...

Students are introduced to invasive species and how they affect the ecosystems they now occur in. They explore the basic life histories of several invasive species that are of regional and or national importance. Pupils investigate how...

Middle schoolers investigate a local forest ecosystem and discover the biotic and abiotic parts of the forest. Students observe the groundcover, understory, and canopy layers as well as collect leaves and bark in order to identify trees...

Students 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, and how...

Students explain why dissolved oxygen is important in aquatic ecosystems. They evaluate the optimal dissolved oxygen levels for living organisms.

Students participate in a demonstration in which they role-play polar bears and habitat components to demonstrate the impacts of climate change on the Arctic Ocean ecosystem.

Students explore how predators help control the growth of prey species for a more balanced ecosystem.

Learners build a Bermuda coral reef to gain a better understanding of this ecosystem.

Students perform experiments to determine the PH, acidity, and buffering qualities of a lake that make them sensitive to acid deposition.

Fourth graders make predictions, observe, collect and record data. They investigate several soil and worm websites. Finally, 4th graders write a letter to The President which defends earthworms by explaining their value to the United...

The vocabulary used in this presentation on salt marshes makes it most appropriate for high school or college level ecology classes. The content, however, is relatively simple; It introduces the flora and fauna of this type of ecosystem....

Students create a bracelet that has different colored beads to represent different parts of the Earth's environment. The lesson has a short summary to be used by the teacher to introduce the concept of Earth Day. The bracelet is meant to...

Students explore the cycle of how each living thing gets food. In this food chain unit, students participate in four lesson plans that highlight animal vocabulary, habitats, and the role of humans in our ecosystem. Students demonstrate...

In this biology worksheet, students answer 22 multiple choice questions on ecosystem. They identify which ecosystem component is described in each of the question.

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

Students explore the diversity of different marine sanctuaries.  In this biodiversity activity students work in groups to explore a sanctuary.

Students perform experiments designed to grow plants and bacteria in a controlled environment.  In this ecosystems lesson students investigate varying conditions for growing plants and bacteria. 

Students identify and explain that remote sensing can detect changes on the Earth's surface that occur over time, and name at least three: urbanization, deforestation, and succession. They select a global change issue to investigate and...

Students discuss biodiversity and how to preserve it before examining biodiversity first-hand in an area close to their school. They collect as many leaves as possible from trees and plants and research them when upon returning to the...

Students use the scientific method to conduct an experiment and use varied methods to gather background information. They correctly use lab equipment and prepare tables and graphs that organize, conclude, and present their findings. ...

Students investigate the presence of exotic and natural species in the ecosystem. They define the differences between exotic and native while looking at one specific ecosystem in Maryland. They write how the exotic species are considered...

Middle schoolers investigate various aspects of transportation while working with different resources to conduct research. The research is used to find information in order to create a presentation that includes writing and graphing.

Students engage in a creative project of making a paper koi pond meant to illustrate the type of life that can be found in the pond ecosystem. They build cultural appreciation for the Japanese by researching the use of the koi ponds.
