Students discover the value of sustainability within our ecosystem. In this ecological lesson, students discuss the importance of a food cycle in our society, and how humans can improve the conservation of a healthy ecosystem. Eventually...

Students relate members of an ecosystem by their interactions. For this ecosystem lesson, students toss a ball to other members of their group (each representing a member of an ecosystem) and tell how they are related to that member....

Learners conduct a series of experiments to explore carbon dioxide properties. In this chemistry lesson plan, students explain the production and uses of this gas. They measure its amount in soda and waste product of yeast.

Fifth graders investigate the food chain by viewing video clips. In this food web lesson, 5th graders investigate populations and ecosystems by viewing a video in class as well as visiting web sites. Students utilize the Internet to...

Students explore the parts of plants and discover that plants need to grow. In this plant instructional activity, students discuss the parts of the plant and plant petunias. Students can share their plants with friends or families.

Students plot data to construct and interpret a graph about vestimentiferans at cold-seep sites in the Gulf of Mexico. In this deep sea instructional activity, students plot data provided for the growth of tubeworms. They use the graphs...

Students research coral reefs and identify their benefits to humans, threats to the reef, how to reduce and eliminate threats, and more. In this coral reef lesson plan, students research the reefs, and take a field trip to an aquarium.

Learners complete a food chain. In this ecosystem lesson, students learn about producers, consumers and decomposers. Learners identify herbivores, carnivores and omnivores and complete two worksheets.

Young scholars explore the differences between food webs and food chains.  In this wetland lesson plan students play a food web game and go on a scavenger hunt. 

Young scholars discuss the importance of plankton in the ocean ecosystem. In this biology lesson plan, students identify the different types plankton by observing them under the microscope. They explain how plankton population affect...

Students use TLC separations to identify various substances.  In this chlorophyll lesson students separate pigments found in different plants.

Students participate in a lab experiment to observe and measure the opening and closing of stomata. They focus on photoperiod, locate and identify stomata on a leaf and explain the role of stomata in the daily functioning of a plant.

High schoolers design, implement, and report a scientific research project using the scientific method. They explain the experiment and its findings through poster, essay , or other presentation method.

Students describe food cahins and the role of organisms. Using a set of organism cards, they color code the organisms on their cards by their role in the food chain. Once a complete chain is identified, they glue it on a sheet of paper.

Sixth graders research the theories on the extinction of the dinosaurs. In this dinosaur extinction lesson, 6th graders view a video clip about scientific inquiry. They work in groups to research the two theories on dinosaur extinction.

Students, in this experiment, collect leaves from two species of trees and the stomatal index on the upper and lower epidermis of each leaf be determined.

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 consider the interdependency of life in a temperate forest by studying selected organisms from an Asian temperate forest and creating a food web.

Students participate in an interactive game to review how living things are classified.

Students explore a variety of relevant lake water chemistry questions, compose responses, and present their results in a poster format. They, in pairs, answer questions about lake chemistry which are imbedded in this plan.

Learners perform an experiment to determine the stomaltal index on the upper and lower epidermis of two species of leaves. Stomatal densities change in response to changing atmospheric levels of carbon dioxide and to annual rainfall.

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.

Students identify synapsis as the key event in meiosis. They explain how synapsis leads to the formation of haploid gametes. Exploration of the differences between the processes of mitosis and meiosis occur. In accordance, explanations...

Students consider that under certain conditions in nature tend to remain the same or move toward a balance. They observe populations and determine the functions (e.g., de-composers, producers, consumers) they serve in an ecosystem. They...
