I am happy because we get to take our laptops home this week, and we have fun activities we're planning to do. I'm also happy we get to be making observations outside in science class. I see my classmates, nightshade, the fence, and our school. I hear some crickets, voices of my classmates, and cars. I smell gasoline and grass. I am surprised to find something poisonous on school grounds, and amazed at how dangerous bittersweet nightshade can be. It was also interesting how the berries spread so quickly. I wonder if nightshade affects animals that aren't birds, and how. How come it doesn't affect birds? What in the bird's digestive system keeps it from dying? Why is there something so poisonous on school grounds?
The organism we found looks exactly like the photos and descriptions on the photo identification card, and fits the description of bittersweet nightshade. Also, the bittersweet nightshade a slim stem that is brown and looks similar to wood. The red berries hang in large clumps on the slender stalks.
The plant we found has dark green leaves, and a long skinny stem. The berries are small, red, and egg-shaped. The leaves are arrow shaped, and have lobes at the start of each leaf.
We are positive we found the woody/bittersweet nightshade because of its telltale red berries and dark green arrow-shaped leaves. The stem of this species is flexible and thin. Around the species' developed habitat, there are vines and shrubs that climb over the plants. Inside the berries are seeds that birds eat and digest to plant new berries. This is our evidence that we found the invasive species bittersweet nightshade.
