Field Notes
I am happy because the sun is shining, the air is clear, and my friends and I are observing nature. I smell the leaves and my Chapstick, and the shaking Pines, I hear the wind, the crackling of the leaves, and my team member screaming (He saw a spider). I See the same screaming team member running, and the beautiful sunshine glinting off the damp grass. I see the forest and my friends laughing and the elegant colors of the fall trees. I am surprised because I saw more foliage than I expected. I also was surprised because the plant we thought to be the Oriental/Asian bittersweet, wasn’t. We had to do a lot of investigating and narrowed the differences down and then decided that the plant we were looking at wasn’t the bittersweet. We had no problems besides the spider scaring my friend.
Supporting Evidence
Photo of my evidence.
Evidence one shows that the leaves are glossy on the top, but a bit prickly on the bottom. Their color is green, and you can also see that the leaves are oval and the edges are toothed.
Photo of my evidence.
The plant is wrapped around a dead branch, like the bittersweet, but doesn’t scale up any trees like the bittersweet.
Photo of my evidence.
Evidence three shows the stem color and size. When the stems are just growing they are light green, when the get older, they turn prickly (thorns) and dark green. The Oriental/Asian Bittersweet has bumps and an orange stem, this plant has thorns and a green stem.

Nice job i liked your evidence.

You might want to make sure that your site photo is of the whole site not just of the Quadrat.

Yeah, we will next time, but we didn't know it was supposed to be further back.

Yes our team worked very hard on this and we wanted to make our notes very detailed. Yes we are doing a biodiversity study, In class we are learning about biodiversity. Thank you for your comment and I like how you put in the last sentence.

Your photos are very clear and i can see that you didn't find the plant you were looking for.

I liked how you wrote your field notes. For some help full notes next time you should find a place that has no spiders so none of your team mates will be screaming and running around. I think you should take more pictures of your working area.

Thank you. And yes, next time we will be aware of the fear of spiders and we will get a better distance picture next time.

FANTASTIC JOB WITH THE UP CLOSE PICTURES!!!!! you guys did a great job! I liked how you could smell your chapstick. :)

Thank you! Our photographer took a lot of time on the pictures. Yes, about two people had on minty Chapstick, so we could definitely smell it :)

Great picture of the stem

Thank you, we tried hard to show the differences of the stems.

Great picture of the stem

Nice team work, Banana Republic! I agree with your conclusion that this is not Oriental bittersweet. It's great that you looked so closely at this vine and ruled out all of the key identifying features of bittersweet.

Were you doing a biodiversity study? I see you found 5 different species. Was the scary spider one of the 5 species?

(your second sentence in your field note would make a great lead sentence in a book!)

Our group worked hard on looking at the details of this plant. We achieved our goal of making this easy to read and very specific. Yes, we were doing a biodiversity study, but the spider was behind our study site, but maybe we would count him as a species if he was in the study site, that is a very good thing to consider. Thank you very much for your feedback and our second sentence would be a good starting sentence for a book, you've given us great ideas!
