1. To be successful today, YOU need: pen/pencil, Do Now half sheet, Notes sheet YOU have 3 minutes to get your materials and find your seat! EXPECTATIONS for Do Now: Sitting in YOUR assigned seat… SILENTLY and INDEPENDENTLY… COMPLETE your Do Now… We have 8 days to the EOG! It’s on Friday, May 29th!

2. What YOU can expect from me today... 1. DO NOW, Review 2. Guided Notes → -Carbon and Nitrogen Cycles -Photosynthesis and Cellular Respiration 1. Tic-Tac-Toe What I am expecting of YOU: 1. SILENT voices when I am talking 2.YOUR focus 3. Engagement - this is the last week we have to review!

3. Biogeochemical Cycles - CARBON ●Carbon is the basis of life on earth found in rocks, oceans, atmosphere, and living things ●CO2 in atmosphere → used to make food by plants ● Humans and other animals eat plants → carbon now in our cells ●Plants and animals die → carbon returned to earth and atmosphere

4. Biogeochemical Cycles - NITROGEN ●Nitrogen is needed to make proteins in living things ●Bacteria is ESSENTIAL to all steps ●Bacteria take nitrogen from atmosphere and make it useable for plants ● Animals eat plants ●Animals and plants die ● Bacteria return the nitrogen to the earth

5. Photosynthesis ●Plants use the energy from sunlight to make glucose. ●The reactants of photosynthesis are sunlight, carbon dioxide, and water. ●The products of photosynthesis are oxygen and glucose. ●The balanced chemical equation: Sunlight + 6 CO 2 + 6 H 2 O → 6 O 2 + C 6 H 12 O 6

6. Cellular Respiration ●Breaks down glucose to release Energy/ATP ●The reactants of cellular respiration are oxygen and glucose ●The products of cellular respiration are carbon dioxide, water, and ATP. ●The balanced chemical equation:  6 O 2 + C 6 H 12 O 6 → 6 CO 2 + 6 H 2 O + ATP

8. Human Health  The three molecules that serve as food for the cell are proteins, carbohydrates, and lipids.  Food energy is measured in calories.  If one consumes more calories than the body uses, then they will gain weight.

9. Human Health  A person who burns calories at a fast rate is said to have a high metabolism.  Basal metabolic rate is the minimum number of calories that a person needs to maintain bodily functions while at rest.  The digestion of food provides the body with the necessary reactants to perform cellular respiration.

10. Tic-Tac-Toe 1. Determine who is X and who is O 2. I say definition/question 2 times...only...YOU talk, YOU miss it, YOU lose 3.YOU or partner finds the right answer first wins 4.YOU or partner that makes tic-tac-toe first wins! EXPECTATIONS  Voices = whisper voice  Remain seated  100% on task

11. Exit Ticket 1) Why is a healthy diet important?  A It maintains a constant body temperature.  B It prevents damage to internal organs.  C It makes oxygen for all the cells in the body.  D It supplies the body’s needs for growth and energy. 2) Why is protein an important part of a healthy diet?  A It is needed to change glucose to energy.  B It is needed to store nutrients.  C It is needed to repair tissue.  D It is needed to produce water.
