QuestionAnswer
Triple Beam Balance To measure wieght of an object(s)
Graduated cylinder To find volume of mass of an object
Beaker To measure liquids
Density Measure of how closley pact atoms are together
Prediction To make an inference on what will happen
Mass The amount of matter an object has
Goggles Eye wear to protect your eyes
Volume Amount of space an object takes up
Observation To see the facts in front of you
Test Tube Small tube that measures substances
Inference To make an educated guess
Atom Small patricle that joins other particles to make up solids and everything
Atomic Mass Protons + Nuetrons
Atomic Number Order of element in the periodic table
Nucleus Middle of an atom
Proton Positive charge of an atom
Nuetron Negative charge of an atom
Electron Negative charge (Nuetron+Proton=Electron)
Valence Electron Electron in outer shell of atom
Ion When number of protons and electrons become unequal
Element Something that atoms compacted together make up
Isotope Take away proton, becomes negatively charged

Element Molecule Listed in the periodic table
Compound Molecule Mixed with other elements to create new element
Reactants Compound or element that changes during a chemical reaction
Products compound or element that is a result of a chemical reaction
