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 down all the atoms and molecules in a chemical reaction, showing both products and reactants.

Chemical properties

The identifying characteristics of a substance; like 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.
Molecule
The smallest part that a chemical compound may be divided into. 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).
Photosynthesis
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+6H2O C6H12O6+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 6CO2+6H2O.

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, Fahrenheit, or Kelvin.

Variables

Things that can change in an experiment, equation, or natural phenomenon that can effect the outcome.
