Newtons 3 laws:1.objects in motion will stay in motion unless an outside force acts upon it.2.Both mass and force are factors in acceleration.3.For every action there will be an equal reaction.

.

Periodic Table of Elements-a way to organize all known chemical elements by atomic number, electrons and similar charecteristics.

PH Scale

Phases of Matter in Atomic MotionSolid- molecules are closely bound together and hold a solid shapeLiquid- molecules are moving freely as well as colliding with one another; hold the shape of the container that it is in Gas- molecules are weak and take the shape and mass of the container that it is in.

measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic.

Mass and Weight- mass is the amount of matter in a person; mass never changes. weight is the amount of gravitational pull on an object; weight depends on location.

Energy Transfer-energy transfer is begun with solar radiation. Plants then absorb this radiation which is eventually passed through the food chain as organisms eat one another.

Atom- atoms are made up of protons,neutrons,electrons, and a nucleus. Each atom has its own atomic number and mass .The atomic number depends soley on neutrons, the more neutrons it has, the larger the number .
