| This is us arriving at Grand Valley State University for our trip to Lake Michigan for our cruise. | When we arrived at Stop 2 the first order of business was to test the clarity of the water in Lake Michigan. | Our teacher, Ms. Webb, helped us test the amount of oxygen in the water. | Our boat instructor gave us helpful directions on how to test the water of Spring Lake. |

| This is the pier at Grand Haven from the boat. This is where the Grand River meets Lake Michigan. The pier is a good place to sit and watch the scenery. | Our instructor showed us by combining lake water with a reaction agent we are able to test the alkalinity levels of the water in Lake Michigan. | One more drop of the reaction agent was mixed in and that showed us the alkalinity. | This is a chart of the data we collected showing Spring Lake compared to Lake Michigan. We found through research that Lake Michigan was cleaner than Spring Lake. |

| These are the samples of the water from Spring Lake and Lake Michigan. The Spring Lake sample had much more plankton and algae than the Lake Michigan sample. This is because Spring Lake has lots of nutrients from things like fertilizer. | We obtained a lot of data from the waters of Spring Lake and Lake Michigan. We recorded all the information in our research journals. | This exotic catfish is also known as the "flying fish". It is expected to eventually come to Lake Michigan. | We collected water using Van Dorn Bottles. We attached the messenger to the line and dropped it into the water. |

| This is the messenger going down to close the top and bottoms of the Van Dorn bottles. | At this station we tested the turbidity of the water. | We used the color scale to see how dirty the water is in Spring Lake. | Professor Llerandi-Roman talked to us about careers and helped us plan our futures. |
