Exploring Magnetism in Solar Flares
Solar flares are the most powerful explosions in the Solar System and play an important role in the Sun-Earth connection. Solar flares are caused by sudden changes of strong magnetic fields in the Sun’s corona. The changing magnetic field converts magnetic potential energy into kinetic energy by accelerating charged gases (plasmas) in the corona. The plasma is channeled by the magnetic field up and away from the Sun. Plasma is also accelerated back down along the magnetic field into the chromo

Modern Day Pyramids
Students investigate the ways in which ancient technologies six types of simple machines and combinations are used to construct modern buildings. As they work together to solve a design problem (designing and building a modern structure), they brainstorm ideas, decide on a design, and submit it to a design review before acquiring materials to create it (in this case, a mural depicting it). Emphasis is placed on cooperative, creative teamwork and the steps of the engineering design process.

"Desalination and Water Purification, Spring 2009"
" Water supply is a problem of worldwide concern: more than 1 billion people do not have reliable access to clean drinking water. Water is a particular problem for the developing world, but scarcity also impacts industrial societies. Water purification and desalination technology can be used to convert brackish ground water or seawater into drinking water. The challenge is to do so sustainably, with minimum cost and energy consumption, and with appropriately accessible technologies. This subject
