GENERAL SCIENCE

• John Dalton used experimental evidences to support his atomic theory.
• Albert Einstein did not just depend on established facts and accepted beliefs during his days, but used these to develop his own theory in a different perspective.
• Metric prefixes are pretty easy to understand and very handy for metric conversions.
• The International System (SI) of Measurement is the system of units that scientists have agreed upon and is legally enforced in almost all parts of the world.
• Technology is defined as the application of scientific knowledge to practical purposes.
• The degree of measurements is affected by the ability to use the measuring instruments properly and the precision of the instrument.
• Isaac Newton recognized the role of Galileo and others in his formulation the Laws of Motion.
• Marie Curie and her husband Pierre had to work on several thousand kilograms of uranium ore to strain a tenth of a gram of pure uranium.
• The International System (SI) has seven basic quantities: Length, Mass, Time, Electric current, Temperature, Amount of substance, and Luminous intensity/light.
• Technology is classified into three kinds: machines, products, and processes.
• Johannes Kepler changed his notion about the popular belief during his time that the planets moved along perfect circles to a more accurate information that these follow elliptical orbits.
• The unit factor method is a systematic technique for solving numerical problems.
• Five new Neptunian moons were discovered in 2002 and 2003.
• Triton is covered with a frosty crust, where active volcanoes shoot crystals of nitrogen that look like geysers.
• 1999 brought Stephano, Prospero, and Setebos.
• The surface temperature of Triton is –390°F, making it the coldest object in the solar system.
• A satellite discovered in 2001 was dubbed Trinculo.
• Neptune has 13 moons, with Triton the largest.
• Line graph is proper to use when comparing two continuously changing variables.
• Graphs readily show patterns of data.
• Controlled experiment involves manipulating one of the conditions or factors that may affect the result of experiment.
• Problem solving involves recalling past experiences, interviewing people who are knowledgeable of the problem, and researching in libraries and research centers.
• Galileo's intensive desire to study heavenly bodies drove him to use a telescope to study the moon, the planets, the sun, and the stars.
• Presentation of Data Tables are easy to read, organized presentations.
• Formulating hypothesis is based on information or data gathered, an 'educated guess' can be made.
• Theory is a hypothesis that can be explained from observations.
• Scientists should always exhibit scientific attitudes like curiosity, logic and system, open-mindedness, and scientific traits.
• Conclusion is a statement about the result of the experiment.
• Controls are factors that are kept constant throughout the experiment.
• Testing hypothesis involves carrying out experiments.
• Dependent factors change as a result of changes in the independent variable.
• Law is a statement which describes what happens but does not explain the cause of the occurrence.
• Independent or experimental factors are changed.
• Scientific knowledge may also be obtained through the use of models and ideas, or through serendipity or accidental discovery.
• Trials refer to the number of times experiment is repeated.
• Gregor Mendel was successful in his study of hereditary traits because he used logical experimental methods and accurately recorded his observations.
• In scientific study, some standards or procedures must be observed.
• Variables are factors that change during the experiment.
• Bar graph is appropriate to use when comparing a changing value with an unchanging value.
• The Ionosphere is a separate layer in the Thermosphere that extends of 62 miles(100 km) to 190 miles(300 km) of the earth's surface.
