Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

Have you ever wanted to know the true structure of E.coli? Does the thought of peering into its "small world" sound exciting? Here is a lesson that allows pupils the ability to do just that. Blossoming microbiologists use...

Students explore the dangers of eating high levels of mercury and how small amounts of mercury in water accumulate in greater quantities in organisms higher in the food chain. They list the health of effects of high levels of mercury on...

Students compare and contrast the characteristics of plants and animals. For this ecology lesson, students observe the outdoors and describe the relationship among different living things. They relate plant diversity with animal diversity.

Fifth graders label the parts of the respiratory system. They distinguish among the functions of its major organs. They construct a model of the respiratory system. They watch an animated video and utilize the Internet for research of...

Sixth graders investigate the role of owls in their ecosystem. In this food chain lesson, 6th graders illustrate an owl food chain, dissect an owl pellet, and analyze data. Students discuss what would happen to owls if there were an...

Sixth graders draw a habitat and write about what they would need to survive in the habitat. They define the input of items such as materials, energy, and information, and what goes out of the habitat. They play a "Habitat Address" game,...

Students investigate defensive mechanisms of insects and organisms.  In this biology lesson, students draw imaginary caterpillars as well as imaginary parasites that will harm the caterpillar.  Students utilize the Internet to...

Young scholars discover how organisms are dependent on one another for survivial. They also discuss how to conserve natural resources. They compare and contrast the different types of symbiotic relationships as well.

Students study the organisms that are found in cold seeps and see how they interact with each-other.  In this biological organism lesson students describe the major features of cold seeps and the process of chemosynthesis. 

Students examine macro-invertebrates in order to better understand their link to the food web. Working in groups, they record observations of several areas of a stream or river, collect samples from the river bottom, and identify the...

Learners investigate the physical, chemical and biological parameters necessary to establish an ecological baseline. Establishing an ecological baseline not only shows the ecological characteristics of a creek but makes the possible...

Middle schoolers examine the factors the affect water quality, and allow for animals and plants to live. They look at how engineers apply water quality information when making stream modifications in order to ensure drinking water...

Students examine the habits of various organism and evaluate the need for conserving natural resources. They role-play as migrating birds traveling between habitats encountering hazards along the way. They observe animals in a...

Students explore the why the balance among producers, predators and prey is necessary in order for an ecosystem to be sustained over time. Through web games and activities, they discover how each component of the food chain works to...

Seventh graders investigate changes in the ecosystem within the school year. They see that ecosystems, communities, populations, and organisms are dynamic and change over time. They, in groups, collect data in quadrants in the fall,...

Students explain the relationship among nutrition, infection and diseases. In this health science activity, students suggest ways to break the nutrition-infection cycle. They brainstorm solutions to prevent infectious diseases in the...

The Burmese python is on the loose ... and he's hungry! Illustrate the differences between causative and correlative relationships through an inquiry lesson. Pupils examine several sources of information to determine if there is a...

Students determine which environmental characteristics make up a favorable butterfly habitat.

Provide high schoolers with their own indoor gardens! Emerging scientists discuss the process of photosynthesis and germinate seeds before growing plants in multiple lighting conditions. The hands-on application allows...

How does nature's hierarchy relate to our local human environment? Answer this question, along with others, as the class visually depicts the natural hierarchy provided by nature. Pupils discuss each piece of the pyramid and its energy...

What a web we weave. Pupils use yarn as the primary resource to create a web depicting the intricacies of a salt marsh ecosystem. They participate in a question and answer session, which leads to an in-depth facilitated discussion...

Um may be the atomic symbol for confusion, but it won't be needed in this lesson. Scholars rotate through seven stations completing experiments, hands-on activities, writing exercises, and analysis. Stations include material on...
