On the boat I learned what the three different types of lakes and that all lakes with eventually turn into swamps. I found that very interesting. The bloody worm thing is awesome and it was cool that it ends it’s life it is a fly. I learned how to measure the disolved O2 in the water. I find it very interesting thatĀ dissolvedĀ O2 is very important for sea life because they need O2 to live.
