Learners explore biology by conducting a nature experiment. In this pond examination lesson, students utilize recycled materials, play-doh and water to recreate a pond and its inhabitants. Learners identify the different elements within...

Students explore the coral reef. In this food chain lesson plan, students study the plants and animals of the coral reef and how they each play a role in that ecosystem. They participate in a class play to demonstrate the types of...

Students experiment with plants. In this plant lesson, students research the needs of plants. Students determine if all plants have the same requirements for growth.  In small groups, students experiment with different plants.

Students explore biology by creating a poster with classmates. For this oceanography lesson, students identify the importance of coral reefs to the ocean's ecology and examine a food web of ocean animals. Students define a list of...

Students explain the importance of chlorophyll in plants. In this biology lesson, students extract chlorophyll from different plant sources using chromatography. They discover the different factors needed for photosynthesis to take place.

Students discuss the importance of plankton in the ocean ecosystem. In this biology instructional activity, students identify the different types plankton by observing them under the microscope. They explain how plankton population...

Learners research about the importance of sea ice to world climate and sea organisms. In this earth science lesson, students create a model of present and future Arctic sea ice communities. They discuss how ice melting affects...

Students perform pH and turbidity test to determine water quality. In this environmental science lesson, students analyze NASA database on chlorophyll-a in the bay. They explain how a small river area affects Chesapeake Bay.

Students be complete a collection of living organisms and systems from the school campus.

Learners construct a model giant kelp and kelp forest inhabitants based on field-guide photographs. Students also place animal cutouts in appropriate positions on or near the plant.

Learners identify the three realms of the Arctic Ocean, and describe the relationships between these realms. They graphically analyze data on sea ice cover in the Arctic Ocean, and recognize a trend in these data.

Students identify the three realms of the Arctic Ocean, and describe the relationships between these realms. They identify major factors that limit primary productivity in the Arctic Ocean.

Students explore the harsh conditions of Spain's Rio Tinto River and research the microbes that nonetheless manage to thrive there. They synthesize their knowledge by creating a reality television show set in the Rio Tinto with microbes...

Learners discuss scientific advances brought about by the Mars Surveyor Space Program which impact on daily life, identify laboratory apparatus like microscopes, slides and coverslips, and use the microscopes to view cells and organisms.

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

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

Fourth graders study food chains, producers, consumers, and decomposers. They play a food chain game and create food chain mobiles or posters. They take a nature hike around the school and observe various parts of a food chain.

Students use the Internet to see photographs of fossils from dinosaurs. They read articles about dinosaurs and birds and what they had in common. They also examine a dinorama site in which they discover why some dinosaurs needed feathers.

Learners investigate the properties of insulation as it relates to whales and sea ice. They research whales and examine atmospheric changes that occur with sea ice variability.

Students explore food chains and food webs in a pond and identify common creatures found in ponds. They look for tadpoles, fish, mites and other creatures in a pond during a field trip for first hand research.

Middle schoolers design a closed system to test the relationships between plants and animals. They monitor abiotic fluctuations within this living system by using a chemical test kit. They observe how living organisms respond to...

Students research and describe the habitat and adaptations of a reef animal. After the student is assigned a habitat, they design and draw a cresture adapted to eat each food and to live in each habitat.

Students explain the main concepts of food webs and food chains. They describe the role of animals, plants, and other organisms in cycling energy and matter through a food web by creating mobiles. Lesson contains adaptations for all levels.
