TUES 9/23 week-7 TOPIC: Recycling Matter  OBJ : 8 & 9 DO NOW : EXT:Study for ExamDUE DATE: Sept 30th DW: Nature WKSHT EXIT: Fill in Level of Understanding and EXPLAIN all the steps in the Water Cycle. (17 words) HANDOUTS to PICK-UP: -Nature Relationships WKSHT TURN IN to ABS box: SEMINAR 2: BEFORE/AFTER SCHOOL:  DW-2.3 Reading Questions -Review 2.3 Reading Questions -Nature Relationships (Due next class) Why is it important to living organisms (see  ) that nutrients cycle? AGENDA ABSENT Science of Life

TUESDAY: ___9__/__23___ OBJECTIVE…  #_8 & 9_____ TOPIC: Recycling Matter Daily Grade- 2.3 Book Pages/2.3 RDG Qs DW GRADE:  2  1  0 TUESDAY DO NOW Q: why is it important to living organisms that nutrients cycle? A: Nutrients continue to be recycled by waste from the cows as well as humans or predators that eat cows.

UNIT OBJECTIVES Add on to each QUESTION every night as REVIEW! 8-   --EXPLAIN the importance of nutrients to living organisms 9-   --COMPARE the biogeochemical cycles of nutrients

Vocabulary These should be done by test day!  -matter  -nutrient  -biogeochemical cycle  -denitrification  -nitrogen fixation

2.3 CYCLING OF MATTER  WHAT YOU WILL LEARN -the importance of nutrients to living organisms -the biogeochemical cycles of nutrients

-LAW of CONSERVATION of MATTER -matter cannot be created or destroyed -matter must be naturally cycled through environment -NUTRIENTS -plants obtain nutrients from air, soil, water -plants convert elements & compounds into organic molecules they use for life processes -bodies of organisms are built from water & nutrients such as carbon, nitrogen, & phosphorus  BIOGEOCHEMICAL CYCLES—background info

 flow of energy -Nutrients flow through organisms in an ecosystem -producer → consumer →ecosystem -Decomposers return nutrients to cycle at every level Ex: grass  cow  humans  back to air, soil, water -Cycling nutrients involves: – matter in living organisms – physical processes such as weathering & erosion

READING Q’s MAIN IDEA: -nutrients move through the biotic and abiotic parts of an ecosystem.

READING Q’s DETERMINE: Why cycles in the biosphere are called biogeochemical cycles -BIOLOGICAL :relate to living things -GEOLOGICAL:relate to rocks/minerals -CHEMCIAL: relate to chemicals

READING Q’s IDENTIFY: -the missing steps of the water cycle pictured on pg. 46 PRECIPITATION EVAPORATION  

READING Q’s SUMMARIZE: -How do photosynthesis and cellular respiration differ? -PHOTOSYNTHESIS -release oxygen -RESPIRATION -release carbon dioxide

READING Q’s DETERMINE: -What captures the atmospheric nitrogen? -nitrogen fixing bacteria -found in water, soil, plant roots

READING Q’s NAME: -the nitrogen compound that is changed by organisms in the soil -AMMONIA

Activity Watch video clips and capture the ecological relationships between ocean species Video Clips

EXIT FILL-IN: level of understanding of today’s objective   EXIT: EXPLAIN all the steps in the water cycle.
