p-Block Elements and Their Compounds – I
Lesson 21 in a series of 36 specifically focuses on elements and their compounds from groups 13, 14, and 15 on the periodic table — including boron, carbon, aluminum, silicon, nitrogen, and phosphorus. Classes learn how some of these...
Curated OER
Nitrogen Fixation, OR What a Gas!
Students gain skill in the design, implementation, and reporting of a scientific research project using the scientific method. They set up an experiment to determine the effect of adding the Rhizobium bacteria to one group of legume...
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...

Matter and Energy
In this matter and energy worksheet, students will complete 10 questions about the transfer of energy through a food chain, the steps of the water cycle, and how the nitrogen cycle works.
Curated OER
Biochemical Cycles: Recycling Carbon and Nitrogen
Students construct flow diagrams of the carbon and nitrogen cycle processes. They identify sequences in each cycle that are affected by human impact and present their research to the class.
