MATTER IS ANYTHING THAT HAS WEIGHT AND TAKES UP SPACE.

GALAXIES AND THE STARS, PLANETS, AND METEORS IN THEM

ARE ALL MADE OF MATTER.

YOU AND I ARE MADE OF MATTER.

WATER IS MATTER.

EVEN AIR IS MATTER.

THERE ARE 3 NORMAL STATES (OR PHASES) OF

MATTER.

WATCH THIS VIDEO ON THE STATES OF MATTER:

ONE STATE IS THE SOLID STATE.

IN THIS STATE, MATTER HAS A

DEFINITE SHAPE AND VOLUME.

WOOD IS A SOLID.

METAL IS A SOLID.

Gold

ANOTHER STATE IS THE LIQUID STATE.

IN THIS STATE, MATTER HAS A DEFINITE VOLUME, BUT NO

DEFINITE SHAPE.

WATER, OF COURSE, IS A LIQUID.

HONEY IS A LIQUID.

AT REALLY HOT TEMPERATURES, METAL BECOMES LIQUID.

Molten gold

ANOTHER STATE IS THE GASEOUS STATE.

IN THIS STATE, MATTER HAS NO DEFINITE SHAPE OR

VOLUME.

GASES TAKE UP WHATEVER SPACE IS AVAILABLE TO THEM.

GAS WILL EXPAND TO FILL UP THE ENTIRE SPACE. GAS WILL ALSO SQUEEZE TOGETHER TO

FIT SMALL SPACES.

Canned air

WHEN GAS IS SQUEEZED TOGETHER, IT TURNS INTO A

LIQUID!

Canned air

THERE IS A 4TH STATE!

IT IS CALLED...

...PLASMA!

WHEN A GAS IS ELECTRICALLY CHARGED, IT TURNS INTO A PLASMASTATE.

PLASMA

WHEN ELECTRICITY IS APPLIED TO THE GAS NEON, YOU GET NEON LIGHTS. YOU’RE SEEING NEON IN THE PLASMA STATE.

HERE ARE 3 OTHER EXAMPLES OF MATTER IN THE PLASMA STATE:

LIGHTNING

WHEN A COLUMN OF ELECTRONS FLOWS FROM SKY TO GROUND, THE AIR THAT IT PASSES THROUGH LIGHTS UP WITH ENERGY. WHAT WE SEE AS LIGHTNING IS ACTUALLY THE AIR WHERE THE ELECTRONS ARE AT, GETTING EXCITED AND GIVING OFF LIGHT.

THE AURORA BOREALIS

STARS, INCLUDING OUR OWN SUN

WORD “PROPERTIES”.

WHAT ARE SOME PROPERTIES OF METAL?

https://youtu.be/nlSemv2fLN8?list=PLp-bdYg7YLtcgbmIMMcaQgiQzw0Mu1TC_

SO, WHAT ARE THE PROPERTIES OF METALS?

METALS ARE:

TYPICALLY GRAY OR SILVER IN COLOR

HARD, YET MALLEABLE

HARD WHEN THEY’RE IN THE SOLID STATE

LIQUID WHEN THEY’RE IN THE MOLTEN STATE

TYPICALLY MAGNETIC

METALS ARE TYPICALLY GRAY OR SILVER. THERE ARE A FEW

EXCEPTIONS, THOUGH:

GOLD AND COPPER

METALS ARE MALLEABLE TO A DEGREE BECAUSE WE CAN MAKE METAL BEND BEFORE IT BREAKS. METAL IS EXTREMELY MALLEABLE WHEN IT IS SUPER HOT. WATCH THIS SHORT VIDEO OF A METAL COIL BEING MADE.

https://youtu.be/Mu_QJEIQ-_s

IN THE SOLID STATE, METALS ARE TYPICALLY HARD.

METALS TURN INTO A LIQUID STATE AT VERY HOT TEMPERATURES.

ALUMINUM MELTS AT 1220°F

IRON MELTS AT 2100°F

COPPER MELTS AT 1983°F

GOLD MELTS AT 1945°F

LEAD MELTS AT 621°F

METALS ARE TYPICALLY MAGNETIC. THE EXCEPTIONS ARE:

GOLDALUMINUM

COPPERLEAD TIN

ZINCSILVER

TITANIUM

NAME THE PROPERTIES OF MATTER. CAN YOU COME UP WITH 15 OF THEM?

PROPERTIES OF MATTER ARE:
