Nitrogen Cycle-Stream Side Science
A thorough background and nitrate sampling lab sheet are provided to share with your young scientists. After discussing the nitrogen cycle with the class, you will break them into small groups and show them how to use their inquiry...
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 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 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 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...

# 21 Measuring Nitrate by Cadmium Reduction
Students design an experiment to evaluate the effects of various treatments on the nitrogen cycle in a freshwater aquarium. They are required to maintain a laboratory notebook of all work, measure the key analytes of the biosystem at...

Fertilizing Chile
Fertilizer can mean the difference between a profit and a loss. Scholars use an online interactive to explore the effects of fertilizing in agriculture. Given information about the nitrogen levels in the soil, they decide the fertilizer...
Learning Games Lab
Nitrogen in Pollutants
Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules...
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
Soil Microbiology- Nitrogen cycle
Students take a virtual trip to a Catfish Aquaculture Pond and analyze soil bacteria to determine how many nitrogen cycle bacteria are present. They graph the number of colonies present and use data to determine ammonium levels in the soil.
Curated OER
Traveling Nitrogen
Students examine the nitrogen cycle and how it releases into the air.  In this nitrogen cycle lesson students participate in several activities that allows them to better understand the nitrogen cycle. 
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
The Nutrient Cycles
Students investigate the circle of sea life by creating nitrogen compound models.  For this oceanography lesson, students discuss sea creatures and where their waste goes.  Students identify nitrogen cycles in the ocean by...
Curated OER
Classroom Aquaponics: Exploring Nitrogen Cycling in a Closed System
Students investigate nutrient cycling in a simplified desktop ecosystem involving aquarium and hydro-ponically grown plants. They set up an aquarium with 10 gallons of water at least a week before the lab is planned and place...
Curated OER
Nitrogen Fixation, OR What a Gas!
Learners illustrate the adaptation and co-evolution of organisms. They examine set up an experiment to determine the effect of adding the Rhizobium bacteria to a group of legume seeds.
Curated OER
"Leaf" It in Your Yard
Students research about the process of composting.   Students apply their research by creating a compost pile at school that will be maintained once or twice a month for the remainder of the school year.
Curated OER
Runoff with Chunky the Chicken
Students are introduced to the on-farm nutrient cycle, which explains feed to manure, to soil, and back to the feed.  They are introduced to the generation of runoff during rainstorms, and the contents of runoff water are more than water...
Curated OER
Weathering
Second graders explore weathering and how the water cycle plays a part in weathering. In this weathering lesson, 2nd graders put gravel and sugar cubes in a jar and shake, simulating weathering. Students use the scientific method to...
Curated OER
The Water Cycle
Fifth graders examine the stages of the continuous water cycle that exists on Earth. They observe a water cycle model that is set up in the classroom and write descriptions of what they see. As a class, they discuss models of the water...
Curated OER
Necessary Nitrogen
Students view a video that presents the biogeochemical cycle of nitrogen. They compare types of soils and consider how different fertilizers affect soil composition.
Curated OER
What Goes Around Comes Around!
Students create an ecosystem in a jar to show a model of the water, carbon, and nitrogen cycle. Working in small groups, they research and present orally the information they find on this cycle.
Curated OER
Campus Nitrogen Budget
Students are given guidelines to college level nitrogen budgeting.  Students brainstorm the campus links to nitrogen budget.  Students pick topics or subtopics for individual or group research.  Students develop research plan, keep good...
Curated OER
Daily and Seasonal Cycles
First graders identify the sun as a source of heat and light.  They identify features of houses that help keep use sheltered and comfortable throughout daily and seasonal cycles.  Students are told that summer is the best season to...
Curated OER
Composting
Using 2-liter bottles, junior ecologists create composting tubes in which they place nitrogen-rich and carbon-rich materials. They observe what changes occur over two weeks' time. Provide more specific direction to your class as to what...
