I was sitting in class one day when my teacher told us we were going to be learning about biodiversity in the different biomes of the world and the creatures and plant life that inhabit them. The only thing is she put a twist on learning the unit. She said instead of her giving us a big lecture on the different biomes and the fauna and flora that inhabit them she told our class of about twenty to choose a biome and make a brochure on that biome.I ended up choosing a deciduous forest and I found it interesting that many of the biomes are classified by how many seasons they have. For example my biome had four seasons Summer,Winter,Fall, and Spring whereas other biomes such as the Tundra only have two seasons Summer and Winter. I also found out from my class mates presenting their own brochures that a rain forest has very poor soil but a deciduous forest has very rich soil I found that very perculiar because one would think that an area with so much life would have very good soil but because of all the rain the nutrients are washed away but in the deciduous forest the ground keeps most of its fertility. A couple other determining factors on the biomes are the temperature the climate and the elevation. I thought the way we learned this unit was very interesting and it probed our thinking and creative abilitys and introduced us to a new way of learning. So instead of learning about envirments that are long gone we could learn about enviornments that interest us.

To Much Algae

    

Pentucket Pond

   

As I was walking around the pond yesterday I saw a frog leap in to the water. As the ripples from the frogs leap disturbed the surface of the water I saw a few fish. Seeing the fish was weird because previously I thought this algae infested body of water was able to sustain no life except the insects which floated on its surface along with the green and brown algae. Seeing this got me to wondering what if their was no algae on the surface? With that question on my mind I went off to find out what was the purpose of algae. I found that the purpose of algae was to oxygenate the pond. If the algae were for some reason to disappear I found that there would be no other plant to oxygenate the water which would cause the fish living in the water to die. I also thought what if the insects floating on the surface were to some reason disappear and I found that the fish would lose their food source and begin to die which would cause the algae to increase and over run the pond and then die. When algae dies it takes all of the oxygen with it which would kill the pond and make it uninhabitable. From my research I found that it is difficult to tell if something starts to die if it will die off completely or it is just being reduced to maintain homeostasis.

Today I went outside to observe what was going on. The first thing I noticed was a big, fuzzy, bumble bee http://www.bumblebee.org/ digging a whole into the dirt beneath a lilac bush.  http://en.wikipedia.org/wiki/Syringa I’ve never seen a bee digging into the ground before so I was surprised. It seemed as if it was taking cover from the weather because it was very windy and rather cold for how it had been the past few days. I walked around the lilacs and it seemed as if they were already passing by; compared to most years where they were just blooming at that point. I walked up my walkway, and I noticed that the daffodils we had were already dead, and I really couldn’t remember when they were ever alive. I was thinking that the poor bee no longer had a place to collect pollen, since all of the flowers were either dead or hasn’t bloomed yet. With out the bees, I couldn’t think of any organisms that would die, except for maybe birds, but that wouldn’t make a big impact on the organisms either. So what’s the point of bees? All they do is sting people, and I guess the honey’s okay though. I felt bad so I took my mom’s columbine flower and planted it outside. I hope it doesn’t die with all of the cold weather we’ve been getting lately.
