QuestionAnswer
Qualitative observation An observation you use with your five senses.
Quantitative observation AN observation you use with numbers.
Inference an interpretation based on observations and prior knowledge
Volume the amount of space that matter occupies
Data facts, figures, and other evidence gathered through observations
Energy the ability to do work or cause change
Hypothesis a possible explanation for a set of observations or answers to a scientific question
Mass a measure of how much matter is in an object
Matter anything that has mass and occupies spac
Observing the process of using one or more of your senses to gather information
Scientific Inquiry the ongoing process of discovery in science-Research-Hypothesis-Experiment-Analyze data-Conclusion-Communicate
Scientific law a statement that describes what scientists expect to happen every time under a particular set of conditions
Scientific theory well tested explanation for a wide range of observations or experimental results
Variable a factor that can change in a experiment
Work force exerted on an object causing it to move
Weight measure of force gravity has on an object
ACCURACY the quality or state of being correct or precise
calibration the action or process of calibrating an instrument or experimental readings
graduated cylinder A graduated cylinder, measuring cylinder or mixing cylinder is a piece of laboratory equipment used to measure the volume of a liquid. Graduated cylinders are generally more accurate and precise than laboratory flasks and beakers
international system of measurment The International System of Units is the modern form of the metric system and is the world's most widely used system of measurement, used in both everyday commerce and science
liquid having a consistency like that of water or oil, i.e., flowing freely but of constant volume.
mass a coherent, typically large body of matter with no definite shape.
matter physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy.
meniscus the curved upper surface of a liquid in a tube.
newton the SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second, and is equivalent to 100,000 dynes
precision the quality, condition, or fact of being exact and accurate.
triple beam balance he Triple Beam Balance is a typical mechanical balance. It has a beam which is supported by a fulcrum. On one side is a pan on which the object is placed. On the other side, the beam is split into three parallel beams , each supporting one weight.
unit an individual thing or person regarded as single and complete but which can also form an individual component of a larger or more complex whole
volume volume definition. In mathematics, the amount of space occupied by an object measured in three dimensions, expressed in cubic units. In physics, the loudness of a sound.
weight weight is the force exerted on a body by gravity.
