General Chemistry
In this chemistry instructional activity, students identify the name and abbreviation of the SI unit for mass, length, time, electric current, and temperature. Then they give the abbreviation for each of the units listed and describe...
Curated OER
Land Use and Nitrogen
Students consider the effects of development on water quality. They test nitrogen levels in waters before and after development, investigate wastewater treatment options and research best management practices to reduce nitrogen loads.
Curated OER
Chemistry and Commercial Fertilizers
Students listen as the teacher lectures about the history of commercial fertilizers. The lesson includes extensive information for the teacher. Following the lecture, students complete a worksheet titled "Nitrogen Cycle Problems." The...
Curated OER
Chemistry Activity 29
In this chemistry worksheet, learners write the balanced chemical equation for each. Then they calculate the mass of nitrogen dioxide created with specific amounts of nitrogen and oxygen. Students also identify how many grams of the...

How Do Nitrogen and Water Cycle?
In this nitrogen and water cycle worksheet, students will brainstorm a main idea about the nitrogen cycle or the water cycle. Then the student will write in three details that support their main idea.
Curated OER
Practice Exam Bonding and Acid-Base
In this chemistry worksheet, young scholars respond to several multiple choice questions relating to bonding and acid-bases. They also identify the various types of bases and how they differ from each other.
