Field Notes
During class today we went out to learn how to do a vital signs observation . It was a great day to be outside, the sun was out and the sky was blue. We went to the road leading to the old elementary school (Morton Ave School) and started doing our survey along the fence line. We were directly across the road from the softball/soccer field.

Nice work, MrsPovak and friends!

Your evidence statements are particularly well written. I like how you describe what the characteristics are of F. japonica and then describe what you saw. You also chose particularly appropriate characteristics to document.

Great work. Thanks for sharing your observation. Keep it up!

cheers,
