Energize biologists with colorful images in an activity that captivates the imagination while demystifying the subject of cellular respiration. Participants build comprehension skills and access core content knowledge by analyzing text...

Emerging ecologists need a full understanding of life, from the inner workings of a cell to the complex relationships among organisms. This examination is meant to assess high schoolers after an entire year course on the living...

Environmental science enthusiasts show what they know at the end of the year by taking this full-fledged final exam. They answer multiple choice, graph interpretation, and essay analysys questions, 73 of them in all. Topics range from...

Students investigate the circle of sea life by creating nitrogen compound models.  In this oceanography lesson, students discuss sea creatures and where their waste goes.  Students identify nitrogen cycles in the ocean by...

The balance of nature can be a wondrous thing! With the 19th lesson of the 21-part series on systems, learners explore the cycle of photosynthesis and cellular respiration using a lab-based activity. Groups set up different test tubes...

Students carry out an experiment to monitor diurnal fluctuations in dissolved oxygen, carbon dioxide, pH, and water temperature. They determine the CO2 and pH of the samples (and optionally, dissolved oxygen). Students complete their...

For this stars worksheet, students read about the different stages in the life cycle of a star. Then students complete 3 short answer questions.

For this Life Cycle of Trees worksheet, students read one page about the life cycle of a trees. Students define 12 terms from the reading.

Photosynthesis seems nothing short of magic: a little carbon dioxide and water, add energy, and poof, you get food! A thorough, collaborative lesson teaches youth the process of photosynthesis thanks to a skit they perform with a group...

Students state the physical, chemical or biological processes associated with these environments: Pelagic ocean zone, California coat Cave, Indiana Barrier island beach, North Carolina Sand dune, Dunes National Park, Colorado Wetland and...

Middle schoolers gain understanding of several of the biogeochemical processes in microbial mats. They acquire knowledge of the different roles of organisms in a microbial mat ecosystem. They understand how microbial mat ecosystems...

Students work in groups, plotting carbon dioxide concentrations over time on overheads and estimating the rate of change over five years. Stacked together, the overheads for the whole class show an increase on carbon dioxide over five...

Students show how microorganisms and the carbon cycle interact. In this microorganisms lesson plan, students show this by using yeast, sugar, and water, and observe the energy flow.

AP biologists aspire to respire with this worksheet. In it, they write short answers to 26 questions about cellular respiration. Topics addressed include the Kreb's cycle, fermentation, and more. Written as a chapter reading...

Sixth graders identify the steps of the different cycles of matter, while learning to use WP utilities.

Students identify the main concepts and ideas of the nitrogen cycle. They review key concepts covered up to this point in ecology including food chains, food webs, energy pyramids, and bio-geochemical cycles.

In this photosynthesis worksheet, students complete 20 various types of questions related to photosynthesis. First, they match each description in the first column with the correct vocabulary term in the second. Then, students explain...

Sixth graders create a KWL chart about microorganisms. In this biology lesson, 6th graders create and label a diagram on a microbial mat. They investigate the processes involved in the carbon, oxygen and sulfur cycles.

Students examine determine the symbiotic relationship between plants and animals as the find ways to naturally reduce carbon dioxide emissions. They study the carbon cycle. They work with probe and graphing calculator to examine the...

Students identify the stages in the water cycle. They observe a local water source and view the cycle in action. They create their own water cycle using software.

Fourth graders investigate the life cycle of a tree by researching the Internet.  For this plant life lesson, 4th graders observe The Life of a Tree website and discuss the life of a tree from sprout to death.  Students create...

These twenty various types of questions related to the cycling of matter and energy require students to match each definition in column 1 with the correct vocabulary term from column 2. Then, students explain what is being demonstrated...

It's a gas. Middle schoolers build a biogas generator following the directions in this resource. After a few days of observation, they demonstrate that the gas given off by the decomposing manure is flammable. The activity concludes as...
