Aquatic Ecosystems

               The health of the aquatic ecosystems is declining fast. This is because of oceans warming, the food chain eating away at everything in it, pollution and more acidic. My personal connection to the aquatic ecosystems are that I eat fish, but in return, I don't dump waste or try to let anyone else dump into rivers, streams or oceans because then these abiotic factors don't harm the biosphere and the biotic factors inside it. Humans play many roles in the biosphere, most bad. Some are secondary succession, causing immigration and emigration of animals from there habitats, limiting factors and predator-prey relationships. I feel that the overall amount of our species does not understand their impact and or don't care about the biosphere. I know this because if people knew what they were doing to the biosphere by creating ecological succession and creating limiting factors such as density-dependent factors and density-independent factors, they would surely stop.

Power Balance Bands

I think that the Power Balance Bands are a scam. In the first video I was almost 100% sure they weren't, but the second video changed my view completely. Also the fact that when they tried the tests with the holograms and the weakest person usually had the hologram or band helped make up my mind.
My hypothesis is that they really didn't test the bands, they just used different amounts of pressure on the people and that, like the doctor said, when the volenteers thought they had the band and it would work because it was the Placebo Affect. I would test my hypothesis by buying one Power Balence Band and disguising it to look like 3 other bracelets I buy. Then I would give each person a bracelet without telling them what is was and test them on their endurance, strength, balance and flexability.
It is necessary to look at all sides of the issue before making a hypothesis or setting up an investigation because if you only look at one side then you may not come across the evidence that changes your mind into thinking the other way.

It's Friday!!!!

What I enjoyed the most this summer because I went to Treasure Island, Florida. We spent 3 days at the beach! But I'm glad were back in school because I get to see all of my friends and learn new things. After the first three days I like the teachers, downstairs and schedule the most out of everything!
