Bio-Bottle Results and Conclusions

 Both George’s and my bio-bottle peaked at about a height of 45 cm and then both died out. The control bottle reached a height of 50cm. It slowly died, it declined to 40cm  and a couple of days later there wasn’t anything left. Variable 1 got to a height of 41cm  and then died.

   The constant bio-bottle consisted of dirt, tomato seeds, water, rocks, and 2 bottles. We put 8 seeds in and gave it 40 ml of water each day. We set up the bottles the same way except for the mount of dirt.

   One of the variable bottles had the broken glass from a light bulb and the other had the metal parts from the light bulb.

1)      My hypothesis was correct I expected that the constant would grow the most.

2)      The constant did the best but only barely so more testing would be needed to determine if light bulbs have a dramatic effect on the biosphere.

3)      We didn’t add the same amount of dirt to each bottle and we didn’t water the plants on the weekend. This could have decreased the growth o the plant. Also Sid didn’t keep track of… anything, so we don’t know if the 2^nd variable bottle had a clear effect.

4)      For the variables we tested we were able to track their progress well, except for the 2^nd variable. We were limited by the fact that we couldn’t test mercury.

5)      Our Lexus project is about recycling light bulbs because they can be harmful to the environment.

6)      Yes it showed that light bulbs, not even ones with mercury, can be destructive to the environment.

CLIMATE CHANGE

   Climate change is a problem that is affecting people and the environment. Climate change may directly affect human health through increases in average temperature. Such increases may lead to more extreme heat waves during the summer while producing less extreme cold spells during the winter. Rising average temperatures are predicted to increase the incidence of heat waves and hot extremes.
   All regions of the world show an overall net negative impact of climate change on water resources and freshwater ecosystems. Areas in which runoff is projected to decline are likely to face a reduction in the value of the services provided by water resources.

sewer treatment

We learned about our sewer system and how it works.  One of the first steps is filteration, there is a huge filter that takes out larger solids.  The water is then pumped into big tanks where micro-organisms break down whats left. After the water is treated it is pumped back into the river.

Down town construction

1) Mrs. Byrely is a secratary

2) The city improved our drainage systems so that when it rains the run off is filtered before it enters the Grand River.

3) Instead of all of the contaminents that are on the island just going to the river with the rain water it is filtered out.

4) There should be less total dissolved solids in the river the next time we test it.

5) The most interesting thing i learned yesterday was that we have pourus parking lots to help filter the rain water.

6) My bio-bottle seems to be doing very well, it is the control so it is growing like it should.

7) I havent done anything for my action project yet im not quite sure what to do.

8)  I am done with a couple of my slides.
