  1. Investigating the factors which influence the carbon fixation of Chlorella pyrenoidosa and the further use Tianjin NankaiHighschool 2012

  2. Here We are

  3. Part 1 Introduction

  4. outline Chlorella

  5. outline

  6. Part 2 Variables & Methods

  7. Hypothesis

  8. Variables and Groups

  9. Conditions: 2×2×3=12 Total samples: 12×2=24

  10. Experimental Method Control Variety Method

  11. Experimental Method 8 days

  12. independent experiment the mass of a single Chlorella cell

  13. Experimental Method m（C）=?

  14. Apparatus

  15. Part 3 Procedure

  16. Step 1: Pre-culture climate cabinet Chlorella

  17. Step2: Beginning Final effect

  18. Step2: Beginning

  19. 500ml

  20. Step 3: number counting • Counting • Sampling

  21. Step 3: number counting • picture of Chlorella in the microscope

  22. Step 3: number counting Counting chamber Microscope

  23. Get the dry weight of Chlorellas Suction Filtration

  24. Step4:calculation @ If: a cells in counting chamber, then: 5a×106 cells in one jar. @ mass of Chlorellas in one jar = mass of one single cell × number @ m(C) = mass of Chlorellas in one jar × 0.59[quoted] @ m(CO2) = m(C) × 44/12

  25. Part 4 DATA & Calculation

  26. The influence of temperature

  27. avoid the scorching sunlight

  28. The influence of illuminance

  29. The influence of flow rate

  30. Best Condition

  31. CO2 Fixation in all According to the data on the 8th day, the total amount of carbon fixed by 24 jars of Chlorella in 8 days is 1.5576g, ie. 5.7111g CO2. 5.7111g CO2

  32. CO2 Fixation under best condition 2) If we use the data of No.11, which grows the best among the 24 jars, we can get the most CO2 fixation rate, in our experiment, as 0.4379 g/L·Day. 0.4379 g/L·Day

  33. If I have a house of 80 meter squares

  34. I’ll change my fish tank into Chlorella

  35. Then the air in my house can be renewed in 1 week

  36. Part 5 Error Analysis

  37. Data cannot match the photos No.10 255 No.9 1409 8th day’s number No.13 456 No.14 612

  38. Analysis

  39. Instrumental error

  40. Theoretical Error V E R S U S

  41. Theoretical Error take samples repeatedly

  42. personal error different habits of using microscope

  43. personal error time difference when taking samples

  44. decreasing of Chlorella??? caused by inexact counting process??? the air from rubber tubing would make the Chlorella splash out of the jars??? Chlorella is actually decreasing??? the air flow rate may be so strong that the cells were broken by the flow??? some creatures in the air to prey Chlorella???
