Can you tell which ones are rushes, which ones are sedges, and which ones are grasses?

My stepdad, Carl Johnson, lets me use his four-wheeler to explore the logging roads across the road from where he lives in Waltham, Maine. Today was a beautiful day, and I had a great time by myself driving a little too fast and finding cool additions to my collection. (I think I owe you an entire tank of gas, Carl!)

Here are my findings. Some day I will be able to tell you what they’re all called.
