Three things that I learned:

1. I learned about the different types of water. Mesotrophic, Oligotrophic, Eutrophic. What I learned about those is what types and how many fish they hold and the turbidity of the water (clearness).

2. I learned about the different types of invasive species, and how they can damage the water and the animals in it. Some of those animals are quagga mussels, zebra mussels, and sea lampreys and how they got to be in these lakes.

3. I also that there are so many things that live in one drop of lake water and that to me that is very disgusting and very scary to me.

Questions:

How many sea lampreys live in Lake Michigan or in Spring Lake?

Why did they let sea lampreys into Lake Michigan in the first place?
