(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

insoluble solid formed when two liquids mix
Precipitate
a thin board with copper lines on the surface
Circuit Board
chemical process that cuts into a solid surface
Etch
A system that does not allow matter or energy to enter or escape.
Closed System
an early sample of a product that provides information about how the device or system works
Prototype
desirable outcome given up to gain another desirable outcome
Trade-Off
final substance at the end of a chemical reaction
Products
saved, neither gained nor lost
Conserved
a minimum requirement for how the design must function
Criteria
mix into another substance at the scale of individual particles
Dissolve
Two or more different types of atoms held together by a chemical bond
EX: : H2O or CO2
Compound
The basic building block of matter
Contain protons, electrons and neutrons
Atom
original substances before a chemical reaction takes place
Reactants
total energy of motion of the particles in a sample of a substance
Thermal Energy
The principle (or scientific law) that mass is neither created nor destroyed during a chemical reaction. See law of conservation of mass.
The Law of Conservation of Mass
Two or more atoms held together by a chemical bond (any two or more atoms)
EX: H2O or O2
Molecule
a symbolic representation of the reactants and products in a chemical reaction
Chemical Equation
something that limits the solution to a problem
Constraint
to retrieve waste material so it can be used again
Reclaim
process that absorbs energy; temperature decreases (product is cooler than the reactants)
Endothermic
process that releases energy; temperature increases (product is warmer than the reactants)
Exothermic
substances interact to form a new substance
Chemical Change
physical form of matter: solid, liquid, gas
State
A system that allows matter or energy to enter or escape.
Open System
process where chemical change occurs
Chemical Reaction
change that occurs when the particles of one substance mix with another substance, particles do not change
Physical Change
amount of matter in an object
Mass
information that supports or refutes a claim
Evidence
