Who done It? Or what's that brown fuzzy stuff on my plum?
A safe and simple exercise that uses Koch's postulates to prove that an observed fungus is the cause of fruit disease. Since the fungus that causes brown rot of stone fruit is present naturally on the surface of these fruit, stone fruit purchased from the supermarket or farm stand will usually develop the disease. The fungi responsible for brown rot of stone fruit are not human pathogens. This lab requires dissecting and compound microscopes. A simplified exercise, without cultures, to demonstra

Pointing at Maximum Power for PV
Student teams measure voltage and current in order to determine the power output of a photovoltaic (PV) panel. They vary the resistance in a simple circuit connected to the panel to demonstrate the effects on voltage, current, and power output. After collecting data, they calculate power for each resistance setting, creating a graph of current vs. voltage, and indentifying the maximum power point.
