A three-week activity where students bury orange peels in two bags, one containing dry soil and one containing ventilated moist soil. The experiment is inquiry as students will discover the importance of oxygen and water for biodegradation. The activity has a STEM component, as the straw tubes can be thought of as ventilation tubes. Also provided is a page of document camera images and notes on biodegradation. Simply print and use.
The mass and surface area of each orange peel is measured before and after. The activity is completely described and the procedure, result table, and measuring grids are included for student’s notebooks. There is also a student result sheet where student discuss the results of the experiment and answer questions.
Here is another three-week Biodegradation Experiment
