2. 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.

3. 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

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

5. 2.3 CYCLING OF MATTER  WHAT YOU WILL LEARN -the importance of nutrients to living organisms -the biogeochemical cycles of nutrients

6. -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

7.  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

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

9. 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

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

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

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

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

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

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