Things that I learned:

• I learned that there are 3 different kinds of lakes Oligotrophic, Mesotrophic and Eutrophic they are all different levels of natural particles in a lake.
• There are many different invasive species in lake Michigan there are some that are getting so bad that they could take over the lake and its natural animals and plants.
• I also learned how to mesure the conductivity of the water which was so cool.   

Things that made me wonder:

I wonder why we don’t take better care of our lakes because we have lots of the worlds fresh water but we let invasive species and garbage take it over. 

I also wonder why we measure the plankton in the water because they are soooo small.
