Biofilm Simulation At The G.C. Marine Reserve

On Friday, March 28th, we did an experiment with graham crackers and other delicious treats. Our teacher had told us all week that we were going to do something with food and we were prepared! The reason for this experiment was to show how much stuff grows underwater. We used different items to show different species/things in the ocean. The paper towel showed water, the graham cracker was a the substrate, the icing was the EPS, red sugar crystals were red coralline algae, brown long johns were diatoms, rainbow sprinkles and marshmallows were barnacles, rainbow long johns were coral, and blue or green dots were oysters. We got each item at a time, sprinkling a little of each thing on our cracker. When we sprinkled some of the items on the cracker, not all of them made it, this simulated that not all species in the ocean attacth which means they die.

Signs Of Spring

Site 1: On our 6th day outside, we went outside...but this time we went out through the front. As we got out through the doors we approached a red tree which was blooming with red flowers. On top of a lightpost I spotted a seagull. I heard a crow flying by. Also, I felt the sun beaming on my skin, but it didn't feel as cold as other days.
Site 2: As we continued on our trip, I saw pine cones starting to sprout. I also saw green moss growing on a dead log. I heard a police dog in the back of a car, and it was barking like it was crazy!! I felt the sun beaming on me more now since there was no more shade.
Site 3: On our way to site 3 we walked through the woods, on a path. When we approached the pond i saw a hole and blooming bushes. I didn't see any ducks, but that's probably because they migrated away. I saw ripples in the water and a black vulture. As we were leaving, I saw larvae on a stick. I felt wind blowing on my face. I heard a dump truck and a bird chirping in the forrest. I thought i heard crickets but that was just Mrs. R's phone.
Site 4: On our last sight i saw a hawk flying towards the pond. I also saw a catepillar, a spider on Josh's paper, and a crawfish chimney. It was interesting to see the chimney because the crawfish had to push or carry the mad all the way up to it's house. I heard birds chirping again. I felt cold because the shade was blocking the sun's rays.
