Earth science experts learn about the roles of nitrogen by taking a virtual journey through the nitrogen cycle. Completing a passport worksheet along the way, they move from place to place around the classroom by the toss of dice. Each...

The nitrogen cycle is the focus of a well-designed science lesson. In it, learners see that plants and animals produce waste products and decompose after death. Many of the waste products include nitrogen which is absobed by other...

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...

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...

An inventive and interesting instructional activity 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...

Students discuss ammonia, and ways it may get into the aquarium. They complete a worksheet about the Nitrogen Cycle. Students learn how to get the ammonia and nitrite out of their aquarium.

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...

The biogeochemical cycle ... no physics? The fourth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program introduces the biogeochemical cycle by having pupils simulate movement between Earth's...

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...

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...

Fixin' to add a great resource to your plans? Scholars perform an experiment to investigate nitrogen-fixing bacteria from plant roots. Along the way, they learn about the concepts of symbiosis and mutualism.

Young scholars design and create a compost pile in order to study the Nitrogen Cycle. They then use the scientific method to determine if plants grow better when they add organic matter from their compost pile to the plant's soil.

Learners investigate the factors that compose the nitrogen cycle. The harmful effects of acid rain and ozone depletion are also discussed in the instructional activity. Students define the nutrient that is often limiting to plant growth...

Here is an interesting science activity. 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...

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...

It's an extravaganza of excrement! Do your pupils understand that waste doesn't really go to waste? Introduce the nitrogen cycle with an interesting instructional activity and lab from the K20 series. The activities include a look at...

Some of the CO2 emitted by burning fossil fuels is removed from the atmosphere by natural sinks, such as the ocean. The fifth engaging lesson in the series of 21 examines the CO2 data from three very different locations. It then makes a...

The fifth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program defines dead zones and how they form. Pupils then examine data from the Gulf of Mexico to determine dead zone formation.

This exam covers every topic in a typical first-year biology course. A wide variety of question styles gives high schoolers every opportunity to show what they know. Why start from scratch when a comprehensive final exam is easily...

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...

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...

Students study the nitrogen cycle and construct a diagram.  In this Earth Science activity students use role play to see the various paths. 

What impact do humans have on greenhouse gas emissions? What are the natural causes of these gasses? Thanks to the carbon cycle, carbon dioxide eats away at the earth's atmosphere with the intensified help of humans. Young scientists...

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...
