Field Notes
When we were on our field expedition we witnessed a little bit of nature, some people, we saw our school. ALSO! We heard cars, some wind breezing, and planes soaring over our heads. One last thing, we smelled some bizarre things such as the fresh air in our noses and the chap stick gloss on mine and a friend’s lips.

The Purple Loosestrife has 5-7 petals on the flower, where the flower we found were in clusters, each flower had 10-15 petals on it, the petals were purple. Purple Loosestrife also has flower spikes where the flowers we found are not spikes. The flowers were small about the size of a bee. Different plants grew close together and each plant had more than 1 flower on it.

This picture shows the way that the leaves alternate where as purple loosestrife has opposite leaves.

I like so many things about this observation.

I like how you paid attention to details in your Field Notes.

I like that you called the plant you found your Mystery Plant.

I like all of your detailed comparisons and measurements.

What do you like about your observation?

(I think you found an aster!)
