Characteristicas of group: They live in shallow water they feed on worms, mussels, and slugs. They come in varieties of colors from dark blue or green to a light colored pink or white color. They have thin shells and no operculum because their bodies are too big to go into thier shell. When babies are made they attach to thier shell and then they detach themselves off the shell and onto a thick mucus thread that gets buried in the sand untill they are born.

All of these foods have some type of algae in them (:.

Plankton #1

This Plankton is micro phytoplankton.

This is a zooplankton it is a meroplankton because it is a worm. It is macro in size.

This is micro phytoplankton.

Biofilm simulation of the G.C marine reserve

We did an experiment on biofilm stimulation we used a graham cracker as our substrate (surface that organisms can attach to) the paper towel stimulated our ocean. The mini-marshmellows, lifesavers, and a variety of sprinkles for our benthic organisms. The little red sprinkles were the red coralline algae, the diatoms were the long brown sprinkles, The barnacles were the rainbow sprinkles and mini marshmellows,Coral were the long rainbow sprinkles, Oysters were the blue and green dot sprinkles. Everyone in our class had different results because of the different amounts of sprinkles people poured out and that changed the amount of marshmellows used in the experiments. This experiment showed what happens in the ocean because depending on where the sprinkles fell it showed their niche.

SIgns Of Spring

One of the first signs of spring we saw was on the perimeter behind the school. There were birds chirping and flying around above our heads and you could see flowers and plants starting to pop out of the ground. It was warm and sunny outside but the wind made it feel so much colder. I could hear birds chirping and the wind whipping quickly past my ears.

Our second sign of spring was around the the outside of our next trail. There were small little white flowers that had started to bloom. I found a tree that was already growing berries possibly for the animals that are going to arrive soon. It was very cold in this spot because we were in the shade and the wind was blowing pretty hard. I could hear the wind shaking the trees and the birds chirping above us in the trees.

The third sign of spring was next to the pond we found cat tail plants that had already grown as tall as me. We found trees with pollen hanging off of them called aldercatains and weeds growing around the pond. The wind seemed to be even worse in this spot because of the shade and being next to the water. It was 43 degrees outside but with the wind chill it felt like below freezing temperatures.

The last sign of spring was in the fourth spot next to a tiny dirty looking little creek next to the school. There were newly growing trees and flowers popping up out of the ground around the creek. The sun was very bright in this spot and it felt somewhat warmer than in all of the other spots because i was standing on the road. I could hear and see cars passing by us and the water in the creek moving from the wind.

Plankton wars

This was our plankton : ). Me and Jeremiah gave her a play-dough head and a sponge body, we stuck a marble and buttons on the bottom to give it some weight so that it could stand up and stay in between the water. We thought the the sponge would make our plankton float but we had to figure out how much more weight to put on the plankton so that it would stay in the middle of the water which was hard because you got to get it almost perfect for it to float in the middle. We came in second place we were 13 seconds behind the winner.

Adventure 6

****Mrs.Richardsons pics****

 In this spot we heard black birds and crows chirping and we seen a red cardinal fly from limb to limb above our heads. It was a warm day except for the wind that i thought was going to blow everybody over. In this picture you can see close up on a pine tree, this image brings the whole forest to life because not many things are alive in the forest in the winter time.

 This is a downy woodpecker that Mrs. R found pecking at the tree above our heads. She managed to zoom in close enough so that you can see the beautiful colors of black, white, and red speckled across it's whole body. The tree the bird is in looks like it has a whit tint to it from the cold frost.

 We found a tiny lizard squirming around under an old rotted down tree. It looked like a little snake at first but then my fellow classmate was brave enough to pick it up,

This is a warbler that Mrs.R found. I think this is a beautiful bird it had a gray and white belly with a yellow body. At this site i heard the wind, cars runnung in the distance, vultures croaking in the background. The wind was very strong today but the sun was shinning so it felt a lot warmer outside than what it really was.

Adventure 5

This is a feather that i just so happen to have stumbled upon when we were walking from one location to another. It looks like a turkey feather that has been laying there for awhile, because it was covered by grass when we first found it.

Adventure 5 (Algae)

This is a small creek that we found in the woods, you can see the algae floating in the water. There is a shadow in the water from the tree above the water where i was taking the picture. I could hear andd feel the wind whipping my hair around my face and It smelled like mildew outside.

This is a different creek that has algae everwhere you can see some floating and some just swaying in the water. There are dead twigs and bushes around the pond. There are no signs of animal life here but there is definately a lot of plant life under the water.

Mrs.Richardson had just happened to have found this while i was walking with her through the woods. It was on the ground almost completely covered by dirt and rocks

 and she just happened to spot it she said it was an old turtle shell. The turtle shell looked like it had been there for awhile it was thin and cracked in a couple of places but it was still a neat thing to find.

This is just a small creek surrounded by rocks in the woods. There isn't very many signs of life but there is some moss growing around the sides of it. It was about 57 degrees outside today, but it was very windy and you could feel that spring time is coming soon.

This is algae in the big pond next to the bus lot behind the school. You can see the algae growing in the water next to the rocks. There were ducks swimming in this pond and you could hear them flapping their wings in the water, and when i watched them for a minute i could see that some of them were mating, which i thought was really neat. They would fly up in the air together and come back down to the water.

Plankton observations

This Plankton is micro phytoplankton because it is eggs or larvae and its a phtoplankton because its a plant not an animal.

This is a zooplankton because its an animal plankton it is a meroplankton because it is a worm. It is macro in size.

This is micro phytoplankton because it is a plants eggs or larvae..

This is zooplankton it is a macro holoplankton because its a permanent plankton.

adventure 4 spot 4

This poop looks just like deer poop it has definately been in this spot for awhile you can tell in this picture that it is very black in color. This poop along with the others did not have a smell, because it has been here for weeks or months.

adventure 4 spot 3

This is a small creek with water running out of this town pipe that is undergroung. There are rocks and stones in the creek. The water is very cold from the below freezing temperature. There are no signs of life here at this point. However, there is grass and mulch that are starting to come back to life. It smelled like trash and i could hear the sounds of birds flying from tree to tree.

adventure 4 spot 2

I found this poop on a log in the woods. Im not sure exactly what kind of animal this came from. It could have been dog or a smaller animal. It didnt have a smell so its been there for awhile.

adventure 4 spot 1

This is poop i found next to the sidewalk. It looks like dog or cat poop maybe. Its hard and dark brown or black in color so that shows that its probably been there for awhile. It doesnt really have a smell because its been there so long as you can see where leaves have blown on top of it.

adventure 3 spot 4

This is the tree next to the high school. It has a big hole in the front where it looks as if there used to be some type of animal living in there. There is mulch around the tree and you can smell the mulch in the air. There are birds above chirping as they fly over.

adventure 3 spot 3

There seems to be a lot of dead weeds hangin onto the side of the pond they are in and out of the water and there are some spots that look green as if the plants are starting to come back to life. as you can see in the picture the wind is blowing very hard on the water causing little splashes. 

adventure 3 spot 2

This is the other side of the pond and it is still slightly frozen from the cold weather we have been having. There are icescicles on the dead weeds. I smelled pine and mulch. i heard the ducks quacking and swimming across the pond.

Adventure 3 spot 1

This is the pond the sun is shining and it definately looks like a place where a lot of living organisms would be found in the spring. There is dead grass and trees surrounding the pond and you can hear the water wrippling from the wind.5t

adventure 2 spot 4

This picture came out really dark for some reason, but this is the big pond that we found behind the school. It is a relatively big pond so i'm sure most animals use this as their main water source. Mostly there were nothing but dead weeds and plants aorund the pond and not too many signs of life. I heard water moving from the wind and i smelled pine.

adventure 2 spot 3

This is another creek we found in the woods there are some spots of green grass growing around it but most of it is dead. There isnt much of a smell..it smells like dead leaves and dead trees. I can hear the branches on trees whistling in th wind.

Adventure 2 spot 2

This spot was near the where the buses park so you can slightly see them in the background. I could hear the buses moving and wind whipping around my face and the slight scent of hay bails. There is mostly dead grass but you can see some green grass growing.

Adventure 2 spot 1

This spot is a tiny little creek that we found in the woods. Most of the grass and trees around it are dead but there is some moss in the background that is alive and a pretty color green. It smelled like pine around these areas and i heard birds chirping above me.

Adventure 1 spot #4

(tyler johnsons pic)

We went outside and it was very cold. I seen lots of old dead trees that were falling over and at this point i was so cold i couldnt feel my fingers and toes. There isnt much life in this area but i still smelled the fresh scent of pine. There were lots of briar bushes in this area and i cut myself a couple times.

Adventure 1 spot #3

(tyler johnsons pic)

We went outside and it was very cold. There were lots of dead trees, and leaves in this area, and there was also a broken down old car that has probably been sitting in that same spot for years. I heard the wind hitting the trees and leaves blowing around. It stunk in this area like old trees and there werent many signs of life here.

Adventure 1 spot #2

(Tyler Johnsons pic)

This area is to the left of the pond on top of the bridge. There are pine trees, rocks, and mulch. I heard the water hitting the pond water and smelled pine. I thought this was a good area to take a picture of because it had the most life.

Adventure 1 site #1

(tyler johnsons pic)

This area is my favorite it has a beautiful pond which was slightly frozen at this time there were buses in the background and you could hear them beeping. There were beautiful pine trees and you could hear the wind hitting the water.
