Bread Mold Lab

In the grade 7 Life Science classroom I am currently doing my student teaching internship in, the students are studying mold and fungus. Prior to leaving for Winter Vacation, the students innoculated homemade bread with spores from a moldy orange, sealed the bread in ziplock bags, and placed the bags in their lab drawers. Today, they took out their samples to view the results. First, the students observed the mold using the dissecting microscope. Second, they prepared wet mount slides to better view the hyphae and spores using the compound microscope. We had some great results. One student decided to try lifting the mold off the bread using scotch tape. She had an excellent result! Good thinking!
