"The solar cells that power solar aircraft are called photovoltaic (PV) cells. PV cells are made of materials that absorb light energy. The PV cells in most solar planes are made of silicon. Silicon is both lightweight and efficient, so it is the best choice for solar planes where the challenge is to create an aircraft light enough to fly but with enough power to get off the ground."

"Discovery of Elements 113 and 115 - Two superheavy elements, elements 113 and 115, were recently synthesized through a collaborative effort between scientists from the Physical and Life Sciences Directorate at the Lawrence Livermore National Laboratory and researchers from the Joint Institute for Nuclear Research at the Flerov Laboratory for Nuclear Reactions in Dubna, Russia. Two isotopes of element 115 survived 30-80 milliseconds before decaying into isotopes of element 113 that survived approximately ten times longer prior to decaying themselves. F"

"The Consortium for Ocean Leadership, representing leading oceanographic institutions universities and aquaria, manages a national academic competition for high schools on topics related to the study of the oceans - the National Ocean Sciences Bowl (NOSB®). The NOSB is a nationally recognized and highly acclaimed high school academic competition that provides a forum for talented students to test their knowledge of the marine sciences including biology, chemistry, physics, and geology. The NOSB was created in 1998 in honor of the International Year of the Ocean and since its inception, the competition has grown to include 25 regional competition locations with 300 schools and over 2,000 students participating annually."

Students will be able to describe the motion of the particles in solids, liquids, and gases. - The particles of a gas move quickly and are able to spread apart from one another. - The particles of a liquid are able to move past each other. - The particles of a solid are not able to move out of their positions relative to one another, but do have small vibrational movements."

"We look at the gas laws and how to recognize which one to use in three sample problems."

"Geographic distribution of acid rain Acidity in rain is measured by collecting samples of rain and measuring its pH. To find the distribution of rain acidity, weather conditions are monitored and rain samples are collected at sites all over the country. The areas of greatest acidity (lowest pH values) are located in the Northeastern United States."
