4. Class Motto
If there is a problem, We look for a solution. If there is a better way, We find it. If we need help, We ask. If a teammate needs help, We give.

10. Vocabulary Energy Matter Law of Conservation of Matter
____________________________ : the ability to do work, or the “fuel” or organisms.
___________________________________ : what organisms and other things are made of.
________________________________________: Matter is constantly recycled (used over and over again). It is NEVER destroyed.
_______________________________ = process in which small _____________________ are passed from one organism to another and from one part of the biosphere to another

11. Water Cycle Evaporation - process of water becoming gas
Transpiration - Evaporation of water from plants
Condensation - changing of water vapor (water in the air) into a liquid
Precipitation - falling of water back to the earth as snow, sleet, hail, or rain
Evaporation - process of water becoming gas

12. Condensation and Evaporation

13. Carbon Cycle There is a lot of carbon dioxide (CO2) in the air.
CO2 is taken out of the air by plants through photosynthesis.
Animals can’t go through photosynthesis so they get their carbon atoms from food they eat.
BOTH plants and animals release CO2 into the air through respiration
Decaying plants, animals, and waste (decomposition) after millions of years will be changed into fossil fuels
Fossil fuels can be burned by automobiles, releasing carbon back into the atmosphere.

14. Nitrogen Cycle
There is A LOT of nitrogen in the air but plants and animals CAN’T use it!
80% of the Earth’s atmosphere is nitrogen
Nitrogen Fixation: To use the nitrogen, bacteria “fix” nitrogen from the air for the plants
Animals get nitrogen from the plants by eating them, in the same way they got carbon.
When plants and animals die, their decaying bodies release nitrogen back into the soil for plants to use.

15. Phosphorous Cycle
Forms a part of life-sustaining molecules such as DNA and RNA
Not very common in biosphere, does not enter atmosphere
Remains on land in rocks and soil minerals
