- Missed Mr.C
- Had to put up with the Haus
- Started and worked on our Bottle Biosphere project
Thoughts And Opinions:
- I thought that the Bottle Biosphere project was interesting and fun. It was also a good way for us to think about and review the biogeochemical cycles and the different trophic levels that we learned about earlier in the unit. I do wish we could actually make one for real!!!
- Could closed artificial biospheres sustain human life??
Above And Beyond:
- A Biosphere Project was built in Arizona at the cost of $200 million US. The scientists had tried to build a 3-acre Earth containing a desert, rainforest and even an ocean. There were many problems though. One of them being oxygen levels. They started declining at 0.3% per month. CO2 levels were extremely unstable as well. They ended up having to pump pure oxygen into the biosphere, hence now destroying the "closed" system. 4 men and 4 women lived in this artificial biosphere and came out extremely depressed and malnourished. This was after two years of living in the artificial biosphere.
