Flux can be view as the rate at which "stuff" passes through a surface. Imagine a next placed in a river and imagine the water that is flowing directly across the net in a unit of time--this is flux (and it would depend on the orientation of the net, the shape of the net, and the speed and direction of the current). It is an important idea throughout physics and is key for understanding Stokes' theorem and the divergence theorem. (less)

Comparing Graphs of Temperature and Radiation

Comparing Graphs of Temperature and Radiation

Solar radiation (light) strikes Earth's surface throughout the daylight hours. Radiation (heat or infrared) also leaves the Earth during daylight and at night. Averaged over time and space, these downward and upward energy fluxes are equal. If they were not, our planet would gradually heat up or gradually cool down. But the surface of our planet is not simply a mirror for radiation. Some of the incoming radiation goes through a process of change before it is radiated back into space. In this lesson, students will analyze plots of temperature and radiation data to determine change over time. (less)

This module was written for a first year accelerated or AP physics class. It is intended to provide hands on activities to teach end of the year electricity and magnetism topics including the magnetic force, magnetic moments and torque, the Biot-Savart law, Ampere's Law, and Faraday's Law. During the module, students utilize these scientific concepts to solve the following problem: A nearby hospital has just installed a new Magnetic Resonance Imaging facility, which has the capacity to make a three dimensional image of the brain and other parts of the body by putting a patient into a strong magnetic field. The hospital wishes for its entire staff to have a clear knowledge of the risks involved with working near a strong magnetic field, and a basic understanding of why those risks occur. Your task is to develop a presentation or pamphlet explaining the risks involved, the physics behind those risks, and the safety precautions that should be taken by all staff members. This module is built around the Legacy Cycle, a format that incorporates findings from educational research on how people best learn. (less)

The seasons on Earth are caused by the tilt of the Earth on its axis as it revolves around the Sun. The differences in climate along similar latitudes can be explained by local variations in heat transfer, such as sea and land breezes. The absorption of solar radiation by different surface materials also contributes to variations in temperature along similar latitudes. Students will learn to correlate surface radiation with mean surface temperature of several geographic regions. By observing how these parameters change with latitude, students will construct an understanding of the relationship of solar radiation to seasonal temperature variation. (less)
