Biogeochemical Cycles Study Guide
The four cycles in Earth's biogeochemical system are covered in this worksheet. Science stars fill in the blanks or define vocabulary terms pertaining to the hydrologic, carbon, nitrogen, and phosphorous cycles. This resource provides a...

The Cycles of Nature
Encourage peer collaboration and assist with the creation of visual aids to identify carbon, water, and nitrogen cycles as your class learns more about nature. They discuss relative information, create a visual aid depicting the chosen...
Curated OER
The Water Cycle
An inventive and interesting lesson on the water cycle (and other cycles associated with it), is here for you. After doing a well-designed hands-on inquiry in class, learners also identify organisms and processes that are involved in the...
Curated OER
The Biogeochemical Cycles
The majority of this presentation is a collection of diagrams and graphs that back your lecture on biogeochemical cycles. The last few slides define ecosystems and the Gaia hypothesis. You may find these slides valuable, but will...
Curated OER
The Water Cycle
Fifth graders identify organisms and processes involved in three cycles: the water cycle, the carbon cycle, and the nitrogen cycle. They produce a pictorial or abstract water cycle, and appropriately place life forms onto an existing...
Curated OER
The Hydrologic (Water) Cycle
Learners construct a model of the hydrologic cycle, and observe that water is an element of a cycle in the natural environment. They explain how the hydrologic cycle works and why it is important, and compare the hydrologic cycle to...
Curated OER
The Water Cycle
Fifth graders explore the major components of the water cycle. They pay close attention to evaporation, condensation, and precipitation. A water cycle kit is set up in the classroom, which learners observe for a couple of days before the...
Curated OER
The Nitrogen Cycle
Fifth graders investigate the nitrogen cycle and examine the concepts of decomposition and nitrification. Students participate in a class discussion about the creation of waste and ammonia compounds, then using nitrogen cycle cut-outs...
Curated OER
Dynamics of Ecosystems
A set of guided notes walks your biology or environmental studies learners through the dynamics of ecosystems. They write short answers to questions about the energy budget, food webs, trophic levels, and biogeochemical cycles. One way...
Curated OER
Ecology
For use early in the year with your ecology class, this collection of slides introduces viewers to cycles in nature and relationships between organisms. There is a food web diagram, but the presentation is incomplete without any diagrams...
Curated OER
The Carbon Cycle
Here is an interesting science lesson. Pupils discover that carbon, just like water, is absolutely necessary for all living things to survive. They study how it cycles through nature, become familiar with the periodic table, and look at...
Curated OER
Energy Flow Through Ecosystems
Middle or high school environmental studies classes will learn much from this presentation on energy in ecosystems. It covers the foundational topics of trophic levels, food webs, and nutrient cycles using informational text and...
Curated OER
Ecological Cycles Part 1
Knowing about the hydrologic cycle is the first step to understanding the carbon cycle. Upper graders discuss the earth's water content, polar ice caps, and the concept of the ecological cycle as it applies to carbon, nitrogen, and other...
Curated OER
Moebius Strips
Students make Moebius strips and use them to demonstrate the interconnectedness of an environment. They explore the natural cycles (water, oxygen/carbon dioxide, carbon, nitrogen) within the environment. They describe how the cycles are...
Curated OER
Biochemical Cycles
When learning about several different processes at a time, it can be difficult to differentiate between them. In the resource found here, you can see what your kids know about some of Earth's systems including the carbon, hydrologic,...

Making Oxygen and Carbon Dioxide
Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for confirmation....
Curated OER
The Living Environment
Students explore the cycles of an ecosystem. In this environmental science lesson, students work in groups to research the nitrogen cycle, the water cycle, or the oxygen-carbon dioxide cycle. Students prepare a PowerPoint or other...
Curated OER
The Carbon Cycle
In this carbon cycle worksheet, students will read about the carbon cycle and study a diagram showing what creates carbon dioxide and what uses carbon dioxide. Students will then complete 4 short answer questions.
Curated OER
The Water Cycle
Fifth graders investigate evaporation, condensation, and precipitation. They observe a water cycle kit and record their observations, and examine how water condenses on the outside of a cup. Next, they observe an evaporation...
Curated OER
Cycling of Matter and Energy
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...
Biology Junction
Ecology
Psychologists study human relationships while ecologist study relationships between organisms in the environment. An introduction to ecology and the related vocabulary benefits scholars as they progress through the presentation and...
Curated OER
The Carbon Cycle
Fifth graders examine the carbon cycle, periodic table, and photosynthesis and respiration. They analyze the periodic table and how it is organized, then complete the "Elementary, Dear Watson" worksheet. Students then examine a carbon...
