Warm up Apr 4 & 5 Why did the Bromthymol Blue turn yellow after you blew bubbles in it? Why did some of the spinach disk float to the surface after sitting in front of the light? Write the reversible reaction for photosynthesis and cellular respiration.

Warm up Review Why did the Bromthymol Blue turn yellow after you blew bubbles in it? Carbon Dioxide put into the water with BTB cause the solution to become acidic changing the color to yellow. Why did some of the spinach disk float to the surface after sitting in front of the light? The spinach cells were completing the process of photosynthesis which produced oxygen gas that then caused the disks to float once again. Write the reversible reaction for photosynthesis and cellular respiration.

Station 6 Summary: Photosynthesis What happens when plants convert sunlight energy? In this activity you punch out spinach disks, forces the air between the cells out and sunk them in a syringe. The spinach disks were placed in front of light with a control that was covered. What did the light do to make the spinach disks float? Think about the products of photosynthesis.

Review: Stations 6 What is the chemical formula for Carbon at the start? NaHCO₃ (s) or CO₂ (s) What Carbon is this supposed to represent in the real world? Carbon Dioxide What is the chemical formula for Carbon at the end? C₆H₁₂O₆ (s) What Carbon is this supposed to represent in the real world? Glucose What made carbon change forms? Light energy Where could this simulation happen in the real world? Any plant organism Write the balanced chemical equation for this station below: 6H₂O + 6CO₂ (g) C₆H₁₂O₆ (s) + 6O₂ (g) Compared with processes in nature, this experiment represents movement of Carbon from atmposphere to vegetation or plants.

Station 7 Summary This station has you focus on three types of scenarios: Aerobic respiration: This is how animals breath…YOU! You will use oxygen and glucose and produce carbon dioxide and water vapor. Anaerobic respiration: Microbes that don’t have an environment with oxygen (intestines, deep in the earth, ocean fume vents, yeast) They get their energy from glucose WITHOUT oxygen and produce ethanol and carbon dioxide. Anaerobic production of methane: Microbes that live in swamps with decaying matter (no oxygen) or intenstines of animals such as cows will take in glucose for energy and produce methane gas and carbon dioxide.

Station 7: Microbial Respiration Why was there a difference in mass? C₆H₁₂O₆ (s) glucose What Carbon is this supposed to represent in the real world? Glucose from plant life What is the chemical formula for Carbon at the end? CO₂ (g), CH₃(g), C₂H₅OH(l) What Carbon is this supposed to represent in the real world? Atmospheric gas and alcohol Where could this simulation happen in the real world? Deep in soil, ocean, intestines, no oxygen areas Compared with processes in nature, this experiment represents movement of Carbon from soilsto the atmosphere.

Station 7 Chemical equations: Aerobic respiration: C₆H₁₂O₆ (s) + 6O₂ (g) 6CO₂ (g) + 6H₂O Anaerobic respiration: C₆H₁₂O₆ (s) 2 C₂H₅OH + 2CO₂ Anaerobic production of methane: C₆H₁₂O₆ (s) 3CH₃ + 3CO₂

Station 8: Cellular Respiration How do large animals move carbon around the world? In this station we had a flask full of water with the indicator Bromthymol blue dissolved in it. After you blew air into the water the water turned yellow. What did that indicate? The color change indicated that the solution turn more acidic (therefore providing evidence that you were indeed blowing carbon dioxide into the water)

Station 8: Respiration What is the chemical formula for Carbon at the start? C₆H₁₂O₆ (s) glucose What Carbon is this supposed to represent in the real world? Sugar from plants What is the chemical formula for Carbon at the end? CO₂ (g) What Carbon is this supposed to represent in the real world? Breath from animals What made Carbon change forms? Process of cellular respiration Where could this simulation happen in the real world? Anywhere with animals Write the balanced chemical equation for this station below: C₆H₁₂O₆ (s) + 6O₂ (g) 6CO₂ (g) + 6H₂O Compared with processes in nature, this experiment represents movement of Carbon from food to atmosphere.

Identify all processes on your map… Use the sticky dots to identify all eight processes on your map. Use the following key and make the key on your map: 1- Ocean Acidification 5-Making Limestone 2-Percolation/Soil Leaching 6-Photosynthesis 3-Chemical Weathering 7-Microbial Respiration 4-Limestone Metamorphism 8-Respiration

QUIZ over Carbon Changing Forms Quiz will be next class You may use your map only on the quiz. You will need to know: how carbon changes with the phases, where in nature does it occur, what process is occurring and drawing a diagram of the process. You will need to describe 3 of the 8 processes, but you won’t know which ones until you get the quiz.

“Carbon on the Move” review worksheet Complete both sides of the worksheet using your journal and map. Worksheet is due at the beginning of the next class. This is a great way to review for your quiz.
