  11. UF Mars Greenhouses

  12. Activities 1. Assembling a Low Pressure Growth Chamber. 2. Uploading of the software program to the computer that monitors sensor outputs. 3. Programming the Temperature sensor – converting °C to °F. 4. Studying the effect of Low Pressure on Gas dynamics in LPGC. 5. Testing a marshmallow/balloon in low pressure to understand Boyle’s Law.

  13. Activity 1: Assembling a Low Pressure Growth Chamber COVER 12V Power supply Base CR10 Datalogger O2 Sensor

  14. PRESSURE SENSOR OXYGEN SENSOR CARBON DIOXIDE SENSOR 4L TEMPERATURE SENSOR

  15. Activity 2: Uploading of the software program to the computer that monitors sensor outputs.

  16. Activity 2: Uploading of the software program to the computer that monitors sensor outputs.

  17. Activity 3. Programming the Temperature sensor °F = °C*1.8 + 32 Step 1: Collect data in °C Step 2: Multiply data by 1.8 and then store value Step 3: Take stored value from Step 2 and add 32

  18. Activity 4. Studying the effect of Low Pressure on Gas dynamics in LPGC Highlight Columns for Time vs. Pressure Figure Sensors Vacuum Pump

  19. CLICK THE FIGURE ICON While Columns are Highlighted

  20. Select XY Scatter Plot then finish

  21. Final Plot: Sketch line in worksheet, repeat for O2% and CO2 ppm, see other groups if your group doesn’t have a sensor

  22. Activity 5. Testing a marshmallow and balloon in the LPGC to understand Boyle’s law Marshmallow Balloon Boyle’s Law P1V1 = P2V2 • Balloon test • Marshmallow test (note: use ruler setup to measure height and diameter of marshmallow in the chamber)

  23. Activity 6. Calculating the photosynthetic rates at Low pressure LIGHT • 6 CO2 + 12 H2O C6H12O6 + 6 O2 + 6 H2O

  24. HAVE FUN and BE SAFE! • ASSIGN GROUPS #s
