____________________________________________ Solar Energy System Design The largest solar electric generating plant in the world produces a maximum of 354 megawatts (MW) of electricity and is located at Kramer Junction‚ California. This solar energy generating facility‚ shown below‚ produces electricity for the Southern California Edison power grid supplying the greater Los Angeles area. The authors ’ goal is to provide the necessary information to design such systems. The solar collectors concentrate sunlight

Gravity Lab Objective: The objective of this lab assignment is todetermine if objects with different mass fall at the same rate or vatying rate in the presence of ar and in a vacuum. Problem: Whateffect does Earth’s gravitational force have on objects of different masses? Hypothesis: If the sand paper falls at the same rate as the paper towel than it will end in the ground first. Objective: The objective of this lab assignment is to determine if objects with different masses fall at the same

been studying the solar system. The learning objective for the students was “I can discuss/apply/evaluate the sun‚ planets and other bodies in our solar system”. My assessment of mastery was done in several forms: class discussion in the form of a jeopardy game‚ student creation of a “postcard” from their favorite planet where they had to write home to a loved one on Earth telling about the characteristics of the selected planet and the creation of a candy model of the solar system.

The Solar System The majority of the solar system is made up of the sun and all of the planets that orbit it. There are also moons‚ comets‚ asteroids‚ dust‚ gas‚ and dwarf planets. The sun makes up about 98 percent of our solar system. Because of the suns large mas it pulls every thing in the solar system towards it. The planets orbit around the sun because of the sun pulling it towards it and the planets trying to fly outer space at the same time‚ which balances it out. It was once believed that

CHRISTIAN HUYGENS Huygens was a Dutch scientist. He lived from 1629-1695. He proposed the earliest theory about the nature of light‚ a phenomena that puzzled scientists for hundreds of years. His improvements on the telescope allowed him to make the first observations of Saturn’s rings and to discover its moon‚ Titan. CARL SAGAN Sagan was an American astronomer. He lived from 1934-1996. He may not have been a great scientist in comparison to others‚ but he is one of the most

combining solar electric and chemical propulsions to escort man on a mission to mars‚ and back to Earth. Even though‚ they both can provide the extraordinary ride it’s their unique performance abilities that sets them apart. In conjunction with using split methods in solar electric and chemical propulsions both transportation methods will also use a split method approach by transporting the bulk of cargo separate from the crew.

divided into two branches: observational and theoretical. Observational astronomy emphasis on acquiring and analyzing the data by using basic principles of physics. Whereas‚ theoretical astronomy focuses on the development of computer or analytical models to explain astronomical objects and phenomena. Both these branches compliment each other.
