There were a few things that I learned about on our trip. For one, I learned quite a lot about limestone, due to one of our tour guides’s obsession with it. Like, it makes things les acidic. Another thing I learned how different invasive species effect our lakes. Like, how sea lamprey have effected our lake trout population. Before, I just knew they were a problem. But now I know how they specifically effect our lake. One more thing I learned was how simple things can determine how our lake is doing. Like, how clear the water is can determine how many creatures (how much plankton) is in the water. I wish I had the opportunity to go back. It made me wonder about some things. For example, do places with less or more limestone get different results/creatures when it comes to water? And how do other minerals effect life in lakes?

I learned that there are strong magnets that can repel sharks. The magnet is made of neodymium.  Neodymium is part of the section called the “rare earths.” Most of the rare earths are from China, about 98%. That was the coolest part. But there was also a cool glass that people can make. You add small amounts of specific metals to make it super strong. Those are some things I learned.
