Decomposers Pre-Lesson Differentiation


Use Tab 3 – Daily Log of the Bread Mold Class Results Spreadsheet to have students keep a daily log of the mass of their Petri dish and bread. This will allow them to observe mass loss each day and may help them identify the pattern of overall mass loss more easily.


Store the Petri dishes and bread together in a cool, dark place, and make sure they are all labeled before the end of the class.

Extending the Learning

Students may be interested in keeping photo documentation of their moldy bread to accompany the data they collect.
