1. Examining reproduction in more detail. The teacher has the students do Activity 48: Fungi Reproduction. The activity has a reading for the students to do and then students complete a chart of the different types of reproductive methods fungi use. Students also examine two websites that show growth and division of budding yeast and binary fission of bacteria. Students also make a graph of a number of yeast cells vs. time and answer:
   • How many yeast do you predict there would be at 60 and 100 seconds? Why?
   • Based on your understanding of yeast budding, and digestion and respiration, explain why the number of yeast in a closed container would eventually start to decrease.
   Lastly students respond to the question: Why do fungi put so much energy into reproduction?
2. Post-assignment conversation. The teacher has students share and revise their responses. She asks:
   • Why is it that you dont see fungi growing on your bread right away?
   • Are the bread mold individuals growing or are these more individuals?
   • Compare how we use energy versus how fungi use energy.

Discussion Question: Which student ideas about reproduction does Janet revisit from Days 1and 2? How does she support students in extending their thinking
