Mold EEEEEEEEEW!

Let's talk about mold.  The question was raised in class; "how did the mold get into the bag?"  I didn't know the answer.  Can anyone fill us in on how the mold that grew on our fruit in the two zip-lock bags that were taped shut got in there?  Any other information that you can share about mold would also be much appreciated.

Chapter 2 Test Prep.

   Hello again everyone.  We have a unit 2 test on Monday.  If you are studying and would like to ask each other a question, run into a problem, or would like to add your expertise, hop on and blog.  Have fun and get out and enjoy the new snow.

Succession and Human Influence

     In science we have been talking about the word "succession,"  and modeled the process using a model of a pond.  We found that over a period of four weeks the water evaporated, seedweed (elodia) died, grass and clover grew, and the whole pond turned into a completely different type of ecosystem.  It took four weeks for our ponds to transform.  What are your thoughts on a real pond?  Why are they around for tens, hundreds, even thousands of years?  Does succession take place everywhere eventually?  Those of you who went on the Superiorview Hike at Wolf Ridge can feel free to chime in here and let us know about the succession of Lake Superior.

 

     On a similar thread; where do humans fit into succession?  We possess the ability to completely change an ecosystem in a short amount of time.  Is what we do concidered a natural act?  What would Prior Lake look like today if humans had not built houses on it and protected the shores from erosion?  Is the way that we interact with the environment concidered succession?  Hmmmm...
