chemical symbol

• a shorthand notation of one, two, or three letters that represent the name of the element

• a numerical representation of an element's atomic mass

• a graphical representation of an element's structure

• a color code indicating the element's state of matter

element

• a unique particle of matter that is a fundamental building block of matter

• a compound made of two or more elements

• a mixture of different substances

• a type of chemical reaction

model

• a representation of an object that makes important aspects easier to see

• a detailed description of a process

• a type of software used for simulations

• a collection of data points for analysis

constraint

• a limitation on the range of possible solutions to a design problem

• an unrestricted approach to problem-solving

• a method to enhance creativity in design

cellulose

• the material that forms the rigid walls and support for plant cells

• a type of protein found in animal cells

• a carbohydrate that provides energy to plants

biofuel

• a material that is made from biomass and releases energy when it is burned.

• a type of fossil fuel derived from ancient plants and animals.

• a synthetic fuel made from chemical processes.

• a renewable energy source that does not produce any emissions.

molecule

• a single atom that cannot be broken down

• a group of two or more atoms that are held together by chemical bonds; a molecule has a unique composition and structure

• a type of chemical reaction that involves the breaking of bonds

• a mixture of different substances that retain their individual properties

producer

• an organism that captures energy and matter from its surroundings to produce sugars and other molecules

• a type of consumer that feeds on producers

• a decomposer that breaks down dead organic matter

• a predator that hunts other organisms for food

atomic composition

• the types of elements that make up a substance, as well as the specific ratios of atoms of each kind of element that make it up

• the total mass of an atom including protons, neutrons, and electrons

• the arrangement of electrons around the nucleus of an atom

• the process by which atoms combine to form molecules

matter

• anything that has mass and volume

• a substance that can be seen but not touched

• a form of energy that can be converted

• a type of chemical reaction
