Field Notes
It was a muggy, hot Maine summer day. All classrooms were hotter then anything. My partner and I had just come from Gym and were extremely happy to know that we were going outside for science. When outside we could smell the freshly cut grass, the damp humid vines, and leaves. You could hear the sound of kids discussing what plant they had found or hadn't. Occasionally you might be able to here the humming of a plane, or the honking of passing cars. All in all it was a great, funtastic science class.

Supporting Evidence
Photo of my evidence.
Our first piece of evidence is that the leaf shape is an arrow head shape. Our packet says that the leaf shape was supposed to be an arrowhead shape, and the plant we found has an arrowhead shape.

The second piece of evidence is that we found out that the leaf arrangement is alternate instead of being opposite or whorled.

Our third piece of evidence is that the plant itself is about 1-2 meters tall. If it was much taller than that, then is wouldn't be a woody nightshade plant.

Hi Donkey,

I am so glad you had such a fun science class outside! The berries in your third photo may be from solanum dulcamara, but the plants in the first two photos are not. Solanum dulcamara ahas a distinctive leaf shape (that is pretty cool looking). Not only is it shaped like an arrow, it also has two lobes at the base that look like ears. Here is a good example:

Good work and keep observing!
