Observe an animation of a thunderstorm
These animated satellite images allow Earth science students to follow the formation of a thunderstorm over central Florida. The introduction explains how thunderstorms are formed by the updrafts of warm, moist air. Students are instructed to observe the animation to see the formation of cumulonimbus clouds and to observe the effect of downdrafts on the storms. The animation is linked to a map of the United States that shows the storm's location. Movie controls allow students to repeat, pause, o

1 A New View of Society
Childcare, education, working conditions, healthcare, crime … these issues are hotly debated in today's society. They are also issues that Robert Owen, seen by some as a visionary and by others as a knave and a charlatan, sought to address in the early 1800s. This unit uses a series of essays written by Owen to explore the ideas of this important and controversial figure.

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.

Myasthenia Gravis - Motor Exam - Muscle Strength Sub-exam - Patient 11
Patient is a 52-year-old African American male who initially presented with diplopia and dysphagia about five years ago. Serologic testing demonstrated antibodies to the acetylcholine receptor, and repetitive nerve stimulation testing showed a decrement in CMAP at slow frequency repetitive stimulation. He now presents with generalized myasthenia, dysarthria, dysphagia and diplopia during a pyridostigmine-holiday for Tensilon testing.
