Graham cracker marine reserve

Our class made Graham Cracker Marine Reserves using icing, various sprinkles, a graham cracker, a lifesaver, and marshmallows. First we put icing on the front of the cracker to create a surface for organisms to fall on and place a dollop of icing on the back of the graham cracker and a lifesaver on top which symbolizes the bolt which attaches it to the substrate. Then we sprinkled on red suger crystals to represnt Red coralline algae and counted and recorded the number of red sugar crystals or red coralline algae. Next we pour out some brown long john to show diatom and recorded their number as well. Next comes the barnacles or rainbow sprinkles and once they were counted up we added one mini-marshmallow for every 10 rainbow sprinkle to show adult diatoms. Then we added rainbow long johns to show coral and we added rainbow flower sprinkles to represent oyster spat.


DAY #6: Signs of Spring

Last week my class went outside to find signs of spring but unfortunately I was out sick with bronchitis. So this week I went outside at my house to find signs of spring in my backyard.
      



 Site 1:
For my first site I went out the door, beyond the porch into the yard to the first couple of trees out back. I noticed the trees had little buds on the branches, the first sign of spring! The wind was blowing gently and it was pretty chilly and overcast outside; I'd estimate around 50 degrees burrrrr! The ground was sticky and wet with red mud. Little birds were chriping and tittering noisily in the trees above my head. I saw a large dark colored bird flying overhead but could not figure out what kind of bird it was. As my boots slid on the slippery wet grass I noticed that patches of my yard had already turned a lush green.


Site 2:
I headed down towards the barn and around the back of it for my second site.The birds disturbed by me, flew out of the stable where they must have a nest hidden. Around back I saw one of our cows and her older calf grazing on the little bit of grass now on the ground. While walking around the fence I found a little green patch of clover on the ground, but unfortunately I couldn't find a four leaf clover anywhere. The sky was heavy and dark with gray clouds and I could feel a few droplets that hit my arm.


Site 3:
Around this time my Granny had spotted me and headed my way, she was walking her dogs Molly and Lucy. After hearing about my search and she lead to her house next door to see some of her flowers. We found a single pale pink flower bud open on a flower bush in her backyard.
We also found small yellow flower buds on a bush in her front yard and the daffodils out front had small green buds but no flowers have appeared yet.




Site 4:After saying goodbye to Granny I headed back to my house and to the front yard. The drizzle that had started stopped suddenly but the sky remained cloudy and it was getting colder. I could hear our dogs barking and cars driving down the road. In the front yard I found some weeds with little purple flowers on them. Near the railroad ties framing the gravel driveway I found some tiny sky blue flowers with little leaves in the grass. I also found some wild onion grass in the front yard as well.

Algae (Food Hunt)

            For homework Mrs.R said we have to find 8 items with at least one of 3 different ingredients called Alginates, Carrageenan, and Beta-Carotene. I found Beta-Carotene first it was in butter, my dad's dietary supplements, V8 juice, and vegetable oil spread. I found Carrageenan in Whipping Cream, strawberry cream cheese, coffee creamer, and evaporated milk. I could not find anything that had Alginates in the ingrediants, but I looked thoroughly which can be verified by my mom and dad who helped me tear up the cabniets in the midst of the search. I think Mrs.R wants us to look for these beacuse they might be algae or some type of marine plant.

Plankton Wars

Our class had a plankton WAR!!!!!!! We all were teamed up and started to design the ultimate plankton; I was pair up with Matt. Our plankton had a flat blue clay head it was flattened to give our plankton more surface area and prevent it from sinking. Two tooth picks was stuck inside the head to make a body and a sponge piece was attached to the other end of the two tooth picks. Then we attached aluminum foil to the bottom in shape of 2 flippers also to keep it from sinking to the bottom. However our design worked a little too well because according to the rules the plankton had to sink below the surface of the water  and lasted the longest before hitting the bottom. Ours floated, enough said.
          So first place went to another team; Karen and Morgan won the war. Their plankton had a flat red clay head and two tooth picks sticking out and a small piece of sponge at the bottom. The sponge was wrapped in aluminium foil which may have possibly stopped the sponge from absorbing and keep their plankton from sinking. Their plankton had a mini pink plastic sword attached to it which might have helped weigh it down so it didn't turn out to be a floater like ours.Also the plankton they made had googly eyes.

DAY 5 (Bird Watching Adventure)

Site 1:
On February 18, our class went outside to observe again and this time we were also looking for birds to see how many we could find in our "backyard" (aka behind the school). At site 1 we went to the pond and on our way there we saw and/or heard 1 crow and 2 seagulls. On the tree lined path to the pond dappled sunlight filtered through the branches high above to rest on the pine needle covered path below. As we came to the pond we spotted 8 geese and another seagull resting on the water. Avery a classmate noticed fish coming out of the pond slightly to eat the bugs sitting on top of the water. It was 75 degrees with a clear blue sky that seemed to stretch on forever interrupted only puffy cotton ball clouds floating by.

Site 2:
We walked around to the side of the pond a little ways to where the flat area around the pond dropped off. Looking down this steep hill i could see trees well over 30 feet tall rising up proud and strong from the ground below. Mrs.R informed us that of the trees below was called a tulip polar tree. Among the trees we saw a squirrel's nest but i could not see any squirrels because we were too far away. The squirrels might not have come out anyway since the buses over at the bus garage were making too much noise rumbling and groaning engines loud in natures silence. It was as hotter than its been all winter with the coming of the change in seasons so by then i was really warm despite the slight breeze.

Site 3:
We walked down from the pond through the woods till we reached the creek which was teeming with life compared to previous visits. We saw a tadpole swimming frantically in the deeper water of the creek and the Mrs.R and some classmates shifted some dead leaves lying on top of the water out of the way and out popped a frog the frog was a brown color but it was not very big a little smaller than my pinkie (my hands/fingers are on the small side but you get the idea).After seeing the frog I was distracted by a sharp pain, like a needle prick, and looked down to see a bright green breir poking me in the arm. Despite this discomfort I was glad to be under the trees and out of the sun, because as I may have mentioned before I was hot
Site 4:
 We walked for a long while farther and farther into the woods and at last we arrived at our destination a part of the creek where the sides widened out into a pool. We saw baby salamanders swimming in this pool and Mrs. R referred to this as a vernal pool. We also saw some more small frogs and managed to catch one and took pictures of the little creature. I could hear the trickling music of the creek flowing across small rocks.
