MATTER anything that has mass and takes up space Three states of matter SOLID GAS LIQUID Particles are close together and do not move very much. Particles move freely in all directions. Particles are not close together and move more freely.
WATER – can go through all three states of matter GAS SOLID LIQUID VAPOR ICE WATER
PHYSICAL CHANGES MELTING POINT (0°C) SOLID TO LIQUID FREEZING POINT (0°C) LIQUID TO SOLID BOILING POINT (100°C) LIQUID TO GAS CONDENSATION POINT (100°C) GAS TO LIQUID
CHANGING MATTER PHYSICAL CHANGE CHEMICAL CHANGE rust A change from one form to another form without turning into a new substance. A change that produces a new substance.
Examples • Wood • Plastic • Feathers • Rubber • Examples • Iron • Copper • Aluminum • Other metals
FORMS OF ENERGY CHEMICAL LIGHT HEAT SOLAR SOUND MECHANICAL ELECTRICAL
SOUND = VIBRATION • Sound travels by waves and it can • travel through matter. • (Sound can not travel in outer space)
SERIES VS PARALLEL CIRCUIT Closed Circuit – when all wires are connected and the switch is down, then the light bulb is ON. Open Circuit – when not all wires are connected or the switch is up, then the light bulb is OFF.
