offspring during reproduction. Charles Darwin’s ideas. Fungi comprise a kingdom of organisms that feed on other living or dead organic material. Fungi reproduce by releasing spores. Molds are a type of fungus. Other examples include yeasts and mushrooms. Fungi grow best in warm, dark, moist places. Fungi are decomposers. The growth of fungi can be inhibited by chemicals. Lesson 14: Investigating Fungi I—The Molds Observe the “mystery print” photo and decide how the print was formed. Decide on conditions favorable for the formation of mold. Compare the rate of mold formation on two types of bread. Observe and document the progress of a fungal garden. Read about the structure of bread mold and the nature of fungi in general. Yeast cells metabolize glucose into alcohol and carbon dioxide. Active yeast rapidly releases carbon dioxide. Some substances promote yeast metabolism others do not. Some species of yeast are helpful to humans others are harmful. Lesson 15: Investigating Fungi II—The Yeast Observe evidence of yeast activity. Design and conduct an inquiry to investigate substances that will or will not promote yeast activity. Explain how different kinds of yeasts benefit or harm humans. Daphnia are crustaceans, a class of organisms characterized by an exoskeleton, gills, two pairs of antennae and many jointed appendages. Internal structures are observed through the Daphnia’s transparent exoskeleton. Lesson 16: The Transparent Water Flea Observe, sketch, and measure Daphnia. Identify its major structures. Determine the Daphnia heart rate under various conditions.
