2.  Matter- Anything that occupies soace and has mass  Energy- the ability to do work  Elements- any of the building blocks of matter, oxygen, hydrogen, carbon, for example  Atoms- the smallest part of an element: invisible by ordinary chemical means

3.  Chemical- is stored in the bond of chemical substances  Electrical- results from the movement of charged particles.  Mechanical- is directly involved in moving matter  Radiant- travels in waves, that is energy of the electromagnetic spectrum

4.  All mater is composed of these limited substances called elements, they're unique substances that can not be broken down into simpler substances by ordinary chemical methods.

5. The word atom comes from the Greek word meaning “ incapable of being divided,” and historically this idea of was accepted as truth. We now know that atoms, although tiny, are clusters of subatomic particles and that, under special circumstances that atoms can be split into these smaller particles which are neutrons, electrons, and protons.

6.  Matter is the “stuff” of the universe. With some exceptions, it can be seen, smelled, and felt. More accurately, matter is anything that occupies space and has mass. Matter can be changed physically and chemically. Physical changes don’t alter the basic nature of the substance, while chemical alters the composition of the substance.

7.  Chemical Changes- Burning wood, fermenting grapes, digesting food  Physical- Crumpling paper, melting ice, cutting food into smaller pieces
