The "Bottled Bacteria" activity instructions are a bit unclear, but the remaining activities investigating limiting factors in ecosystems are well-written. Learners model the exosystem of a bear and a herd of deer. They set up a...

How does a population's habitat determine the size of that population? Teach learners about carrying capacity and limiting factors with an engaging roleplay activity. Class members pose as a colony of penguins who must gather food amidst...

Observing plant succession doesn't have to be a decade long process. A hands-on lesson has groups study succession over a designated space. Learners use their observation skills to record differences in plant and soil characteristics in...

Students compare and contrast abiotic and biotic factors. They discuss how these factors effect ecosystems. They answer questions to complete the lesson.

Sixth graders create a Bahamian terrarium. In this Bahamian ecosystem lesson, 6th graders watch a PowerPoint to see Bahamian biotic and abiotic factors. They bring in 2-3 items for their terrarium. 

Written for an exploration of shoreline ecosystems on Sheffield Island, this gives ecology or marine biology buffs a hands-on experience. Using GPS or visual triangulation techniques, they lay transect lines on a high and a low energy...

Tenth graders create food web displays in the classroom. In this ecology lesson, 10th graders identify the different pollutants in the environment and their effect on organisms. They collect samples of sediments from the harbor and...

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...

Students examine the concepts in the ecological organization unit.  In this ecological lesson students explore news articles that have to do with the study of ecology. 

At first glance, grassland ecosystems might seem dull and uninteresting, but once you start to explore it's amazing the things you'll find! Through this series of engaging lessons, activities, and experiments, elementary students examine...

Students gain an understanding of necessary components required within a healthy, sustainable environment and ways human actions can impact that balance while discovering how to recognize and analyze explanations and models used in...

Students describe the roles of controlled, manipulated and responding variables in scientific research. They also identify biotic and abiotic interactions affecting the makeup of a plant community.

Students 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.

Students seek scientific and technological solutions to envrionmental problems. They record class activities in a journal. They identify relationships among living things and their environments.

Brainstorm ideas to design a sustainable guest village in the Sonoran Desert. The first installment of a nine-part unit teaches young environmental scientists about the basics of the Saguaro National Park and about sustainable design....

Students explore the basics of ecology through numerous hands-on and relevant activities. They participate in an online food chain demonstration, which explores food web dynamics. They dissect owl pellets, examine the prey's bones, and...

Students discover correlations in food preferences of invertebrates, and assess stream health through use of kicknets, invertebrate keys, CBL systems and probes.

Student develop a hypothesis regarding the effects of either mowing or fertilizer upon the diversity of plant species in a grassland ecosystem. They set up experiment field plots and measure species richness.

Students observe reproduction and behavior in several types of animals and nurture a sense of responsibility and cooperation. They then examine external features of several different types of animal groups.

Students search stream beds to study the life cycle and adaptations of stream insects. They explore creeks and streams to see the diversity index of creeks or streams and to find the water qualit index.

Students examine the role of carbon in the oceans and how phytoplankton determine the levels present. In groups, they practice measuring primary productivity using two methods. They use the internet to research the role of phytoplankton...

Seventh graders research Chinese agricultural needs and practices. They conduct an experiment with aquaculture and germinated rice as they take measurements and apply the scientific method.
