Science Language Students Should Know and Use
Atom
The smallest part of an element which maintains the properties of that element.
Chemical change
Changing one substance into another substance resulting in a different arrangement of atoms and thus giving it new characteristics or properties.
Chemical equation
A shorthand way of writing all the atoms and molecules in a chemical reaction, showing both products and reactants.
Chemical properties
The identifying characteristics of a substance such as color, taste, heat content, effervescence, that makes substances behave or react the way they do.
-
Combustion
The process of oxidizing or burning a substance that produces light and heat.Energy
The ability to do work.Energy types
Kinetic, Potential, Chemical, Thermal, Nuclear, Electrical, and Gravitational.Experiment
The process of going through the scientific method to prove or disprove your hypothesis.
Matter
Anything that has mass and takes up space.
-
The smallest part into which a chemical compound may be divided. In chemical form, these are expressed with the chemical symbol and numbers representing the number of atoms of that atom. An example is: H2O (water).
A chemical reaction that occurs in plants. Using light energy, plants change carbon dioxide (CO2) and water (H2O) to sugar (C6H12O6) and oxygen (O2). The reaction is written as:
6CO2+6H2OC6H12O6+6O2.
Physical change
Changing characteristics of a substance such as; size, shape, without affecting the chemical makeup of that substance.
Physical properties
Mainly the size and shape of a substance.
Products
-
Any chemical substance formed as the result of a chemical reaction.
Reactants
The chemical substances that are used during a chemical reaction.
Research
The process of reviewing, analyzing, testing, experimenting, and documenting discovery.
Respiration
The process of using oxygen (O2) to break down sugar (C6H12O6) into carbon dioxide (CO2) and water (H2O). This reaction is the opposite of photosynthesis. Instead of using energy, energy is given off. The reaction is usually written as:
6C6H12O6+6O2
Rusting
The process of oxidation; a chemical reaction that combines O2 with iron to produce a reddish or brownish residue.
Temperature
A measurement of the amount of heat energy contained in an object. Scientists express temperature in degrees Celsius, degrees Fahrenheit, or the number of Kelvins.
Variables
Things that can change in an experiment, equation, or natural phenomenon that can affect the outcome.
