Transcript of Matter cycles
Sandwich Making
• 1 patty of meat• Ketchup• 1 slice o’ Cheese• 2 bread buns
• When you put these together, what do you get?
• Would you be more full if you ate these things together instead of apart?
Baking
• ½ stick of butter• 1.5 cups of flour• ½ cup of milk• 1 cup of sugar• 2 eggs
• If we were to combine these items and cook them, would they change?• Chemically?• Weight?
Burger and Cake
• Whether the ingredients are eaten combined or eaten separately, the same amount of food is eaten.
• This is similar to the conservation of matter–Matter can neither be created nor
destroyed.• This is true with things that are combined or
with things that actually change the way they look.
Impossible.
• You can’t destroy matter. Period• If you blow up a TV, there is exactly the same
amount of matter before the explosion than after.
• You disconnected different atoms and destroyed your ability to watch SpongeBob but you didn’t destroy the matter.
What do all of these have in common?
The H2O Cycle

when you take a breath?
• How much of the air that you breath is made up of oxygen? Nitrogen? Carbon dioxide?
• Nitrogen=• Oxygen =• Carbon Dioxide =
~78%~20%
<1%

Next time you…
• Drink water• Eat a plant• Inhale oxygen• See an abandoned parking lot
• Remember that if it wasn’t for nature’s laws allowing that to happen, you would not be able to live
