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.

Star Quiz 4 Clear your desk of everything but a blank sheet of paper and a pencil. Head your paper Write the version at the top Write just the letter of the answer When finished: Organize binder and get out research question for the science and engineering expo for review

Objectives I can identify a testable research question for the Science and Engineering Expo using the 5 question rubric I can identify the steps of the Biogeochemical cycles.

Research Question Review Exchange your research question with your shoulder partner Grade the research questions based on the following rubric

Notes 1.10: Biogeochemical Cycles THINK: Bio = Geo = Chemical = Cycle =

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 Matter Law of Conservation of Matter Biogeochemical Cycles molecules

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

Condensation and Evaporation

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.

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.

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
