An Investigation into Effects of Rhizobium Soil Bacteria on Nitrogen Availability
Young scholars identify the control and the variables in the experiment. They describe the growth of plants with and without nitrogen fixing bacteria, then name the bacterium responsible for making nitrogen available to the plant.
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 viewing...

AP: Chapter 37: Plant Nutrition
Two pages of questions provide a brief overview of plant nutrition. Biology or botany brainiacs describe how plants absorb and transport nutrients, they explain the role of different bacteria, and they describe a variety of unusual...
Curated OER
Formula Calculation
In this chemistry worksheet, pupils determine the formulas of compounds with the indicated compositions. There are six compositions to solve on the sheet.
Curated OER
Chemistry Worksheet (Mole)
In this chemistry worksheet, young scholars identify and name the number of neutrons, electrons, and protons for each. Then they illustrate how the electrons are arranged in a cloud. Students also find the relative number of atoms in the...
Curated OER
Percentage Composition
In this chemistry worksheet, students find the formula weight for each of the substances listed on the sheet. Then they find the percentage composition as indicated.
Curated OER
Acid-Base Chemistry
In this chemistry worksheet, pupils write the balanced equations when a significant reaction occurs in each. Then they rank each element in increasing order of acid strength. Students also rank the strengths of each of the listed bases.
Curated OER
Ketones and Aldehydes – Reactions 1
For this chemistry worksheet, students complete each of the reactions listed on the sheet, following each step carefully. If no reaction occurs, then they write N.R.
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...
