  1. PHYSICAL SCIENCE

  2. MAGNET=IRON OR STEEL S N S N Opposite poles attract or pull on each other. S N N S Like poles repel or push away from each other.

  3. ELECTROMAGNET A temporary magnet created by a flow of electric current around an iron bar that can be turned on and off.

  4. 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.

  5. WATER – can go through all three states of matter GAS SOLID LIQUID VAPOR ICE WATER

  6. 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

  7. 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.

  8. Examples • Wood • Plastic • Feathers • Rubber • Examples • Iron • Copper • Aluminum • Other metals

  9. BUOYANCY VS DENSITY

  10. MIXTURES VS SOLUTIONS

  11. FORMS OF ENERGY CHEMICAL LIGHT HEAT SOLAR SOUND MECHANICAL ELECTRICAL

  12. SOUND = VIBRATION • Sound travels by waves and it can • travel through matter. • (Sound can not travel in outer space)

  13. 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.

  14. Tinted Anything with a lens

  15. SIMPLE MACHINESARE TOOLS THAT MAKE WORK EASIER.
