Field Notes
FIELD NOTES DAY 1 WE hear the kids in our class running and talking about their object.Also we hear the singing of birds in the distance.We smelled the wet grass and leaves.IT SMELLS LIKE FALL! Some of the problems we ran into was we knew it was a species but we didn’t know if it was ours.We are surprised by what we found because in our area there are more than 1 types species.Also “because it was so easy to find a lot of different species” said one of our members of our team.Also the species we fond looked a lot like the species we where looking for. DAY 2 Today is the second day of our adventure.

Supporting Evidence
Photo of my evidence.
The leaves are ridged, but on the Knotweed, the leaves are smooth.
Photo of my evidence.
Not as tall as it said it was. Smaller than a 2 foot tree... But the Knotweed said it was almost 3 m tall.
Photo of my evidence.
The leaves are whorled, but the Knotweed's leaves are alternate.

Hi YellowSquirrels,

You all did a thorough job of collecting evidence - awesome! And I completely agree with your conclusion. Definitely not knotweed.

I'm glad you noticed that there were a lot of species around. Amazing what you see when you start looking, isn't it?
