Introduction To Magnets The students will familiarize themselves with several different kinds of magnets. They will observe the forces of attraction and repulsion between the different poles, and the forces of magnetism, electromagnetism and static electricity.
Atomic Theory Rutherford's gold foil experiment, performed in conjunction with Geiger and Marsden, provided evidence for the nucleus due to the scattering of alpha particles. The repulsion of some alpha particles suggested that the nucleus is positively charged, containing protons.
Sun-Centered Physics To use a coronal mass ejection (CME) to determine the relationship between position, average velocity and average acceleration and to analyze the motion of the coronal mass in terms of the forces acting on the body (Lesson 1)..
Control a Nuclear Power Plant The control-room operators of the Kärnobyl nuclear power plant are telecommuting and are running the plant through the Web. However, the mean time between failure for the components of Kärnobyl is not great. Try to keep the reactor stable when component failures occur!
Ring of Fire Becoming educated in physical geography requires an understanding of the theory of plate tectonics and the Earth's geological history. In this lesson, students will learn more about these concepts as they investigate the region known as the Ring of Fire, where 75% of the Earth's active and dormant volcanoes are located.
Solar Energy Experiment The purpose of the following experiment is to demonstrate that energy from the sun can be collected and stored in many ways.
