General Science

• Controlled study is a research study that has a controlled set-up
• Controlled set-up serves as the benchmark for a future study
• Experimental set-up measures the impact of the experiment conducted
• Controlled set-up has no manipulated variable
• Experimental set-up has a manipulated variable
• Being open-minded means that you are objective "relying on facts" and you eliminate biases
• Being rigorous means that you check more than one side
• Ethics are the standards of the society
• In 1997, Dolly (Sheep) cloning was conducted
• Hypothesis is the preliminary answer to statement of the problem
• Dependent variable is a variable that depends on the manipulated variable
• Limiting factor is a factor that limits a variable's activity
• Manipulated variable is the variable being tested in a study
• Solids are more compact in terms of geometry. Their molecules move in a constant motion called vibration
• Reflection is a process of heat transmission. There is a throwing back, and has no absorption
• Conduction is a process of heat transmission wherein one object interacts with another object.
• In conduction, object with higher temperature transmits heat to an object with lower temperature
• Thermal equilibrium is achieved when two objects where heat transmission occurs has the same temperature
• Radiation is a process of heat transmission that occurs through electromagnetic waves
• Convection is a process of heat transmission that occurs in liquid and gas.
• Diamond is organic and carbon-based
• Softer minerals cannot scratch harder minerals
• Generally, the heaviest matter is the densest matter
• Polar or Non-polar?

  Water is polar
• Polar or Non-polar?

  Petroleum is non-polar
• Polar or Non-polar?

  Toluene is Non-polar
• Polar or Non-polar?


  Oil is Non-polar
• In Mohs' Scale, Diamond is ranked 10 which means that it is the hardest mineral
• In molecular geometry, diamond is considered tetrahedral or octahedral
• Atomic mass of nitrogen is 14
• Atomic mass of carbon is 12
• The densest object will settle at the most bottom
• In water cycle, evaporation occurs in the bodies of water.
• Evaporation turns liquid into gas
• In water cycle, condensation allows cloud formation
• Condensation turns gas into liquid
• In water cycle, precipitation is the falling back of water into bodies of water
• Transpiration happens when there is evaporation of water from plants and trees.
• Transpiration happens through a plant's stomata.
• Tropical rainforests occur because trees form clouds of their own.
