Emma recently visited the National Mississippi River Museum and Aquarium in Dubuque with her Envirothon team. She was gone a couple of days, so could really see and do many things.
They had free run of the museum after hours, which they greatly enjoyed.
You can never have too much instant ocean!
They did some stream biological assessments – here trying to chase minnows and fish into a net. They also set up fish traps on the Mississippi and were able to catch some monster northern pike and walleyes which was a thrill for Emma!
