Food Web Game
In this game we had four animals to choose from; a seal, whale, bird, and a penguin. I played this game two times the first time being a seal and the second time being a bird. I died the first time and lived the second.
When I was the seal I only ate krill which so did everything else accept the bird. I sadly had to move away from my regular habitat to find food. As the bird I ate salps and krill so I made it in life.
We learn after that experiment that krill are starting to decrease and they are trying to find the reason why. They are doing experiment in Antarctica that they are finding some reasons. The food web game was a good game to play to realize the need for more krill. Bonni B.

Brine Shrimp
This experiment was to see how well brine shrimp grew in different water. This experiment lasted around two weeks. There was four of us in one group and we had ninety brine shrimp eggs.
There was three bottles and each was labeled A-C. Bottle A was filled with regular tap water, bottle B was filled with vinegar water, and bottle C was filled with hot vinegar water. After they were filled up thirty eggs were put in each bottle. After that they were put under a heat lamp and data was recorded every day.
The shrimp grew better in the regular tap water because the acidic level was low. The reason we did this experiment was to show how shrimp have a hard time growing in acidic water. That is what is happening to the ocean and if we don’t do something our oceans won’t be able to grow any life. Cody P.
Food Web Game
The food web game was a game to help us understand the struggles that the animals go through and how humans can either make it harder or easer. This game gets the players attention and teaches them how food sources means a lot in Antarctica. If an animal doesn’t have enough food they have to move or die.
In this experiment we got into groups of five and picked animals we wanted to be. There was a bird, penguin, whale, seal, and a fish. Each animal took so much krill and when an animal didn’t have enough food they had to move away. Each round the amount of krill got smaller and more animals moved away. The reason the krill moved was that the ice melted and the krill moved to find more ice.
The main idea of this experiment was to show students what happens when there is not enough food to go around. It may influence someone to want to help the animals and their habitats. This is a good game to learn about food sources and how much it impacts animals and their environment. Cody P.
Food Web Game
In my biology class we have played a game. There were four characters that we have gotten to choose from. The characters included an Adelie penguin, a Humpback Whale, Mackerel Icefish, and the Cape Petral. The goal of the entire game was to see who would survive. It is relevant because it teaches us about the food situation in Antarctica.
The point of the game was to see who could survive. Now, we all have those friends that decide to be the one who wants to eat all the krill when he could actually eat the salps. There was only one character that could eat the salps and that was the Cape Petral. We were supposed to go around the table and eat our certain amount. I was the Adelie penguin and I was fortunate enough to survive along with the Cape Petral player. Daniel J.
Brine Shrimp
In the last few weeks in biology we have been conducting an experiment. We had to grow brine shrimp and collect data throughout their growth. It was rather hard to do because the information was hard to follow. The main things we checked with the brine shrimp was the pH of the water and we also checked the temperature frequently.
This experiment was a colossal pain when your group members do not want to help always. It was a good way for us to come together as a group afterwards, and for us to work as a team. The average pH for our different types of water was at about a 6-7. This was a good experiment for us to learn about how the water affected the growth of the shrimp. Although we had no success with the survival of the shrimp, we were still able to gather all the information we needed. Daniel J.

The brine shrimp that we grew in the class room were supposed to represent the krill in the ocean. We found that the shrimp died every day and that it was very hard to keep them alive because there was so many of them. It is important to know how the population of krill in the ocean rises and falls in the years that pass it is relevant for the scientists to know so that they can study what happens to the animals that feed on these little shrimp.
The experiment that we had conducted was not entirely easy to do in the small; amount of space and the lack of heat needed for the brine shrimp to grow properly. We found that at least one or two of the small shrimp died each day and that they were not being fed any food so that probably did not help either. We also found that without the proper care and food that the brine shrimp did not live in a controlled enough environments for them to survive. The brine shrimp had changed in size but their size did not drastically change like the whole class had hoped. The whole class had hoped that none of the shrimp would die over the course of this experiment.
To further explore how this experiment works just buy your own brine shrimp and use vinegar and water and three bottles and conduct your own experiment. But be careful on what you use as containers to hold the brine shrimp because certain containers can cause them to die faster. This experiment is very time consuming so be sure to have plenty of time to do it. Eric M.
Brine Shrimp
The Brine Shrimp experiment was done to see if we could grow the shrimp in either, water, vinegar, or warm water and vinegar. Some groups had success with this though some did not. The brine shrimp would either grow or die and most of the shrimp died. The different bottles of brine shrimp would all have different outcome.
We first had to count about thirty some shrimp we placed them in a jar and checked the temperature and pH, and the amount of shrimp that had grown. Some shrimp seemed to hatch sooner than the others, while others hatched later or not at all. We labeled the bottles A, B, and C. A Contained water, B contained vinegar and C contained warm water and vinegar. Because the bottles were clear and the shrimp were small and hard to see we had to use black paper and stuck it behind the bottle in order to be able to see it. We tried to keep the pH at seven before we did the experiment.
The different bottles of A, B, and C all had a different effect on the outcome of the experiment. I think that the bottle that contained the water probably grew the most brine shrimp. The container containing vinegar and the container with warm water and vinegar I don’t think they grew little if at all. Rebekah R.
Brine Shrimp
The past few weeks in biology, we have been doing a lab over the growth rate of brine shrimp. I wasn’t a really big fan of this experiment. I found it rather difficult to follow.
In this experiment, we put approx. 30 shrimp in 3 different types of water. We were supposed to test the pH level and count the brine shrimp. I think our information is most likely inaccurate, because we really couldn’t tell how many shrimp there where. The experiment itself wasn’t necessarily flawed; I believe it was just our lack of knowledge over the subject. I think if we went over it more, we would have gotten better results.
I would like to continue this project, that way we would have the accurate results that are needed. I know that it would have been more fun, had we understood the project. I would recommend to anyone that is going to do this experiment, to do additional research.

Shells & pH
This experiment in Biology was to find the acidity and pH of water, vinegar, salt water and how these substances would affect clam and scallop shells. This experiment showed that different kinds of substances can affect the ocean; they could destroy ocean life in only a matter of days. The shells would help to show how exactly the ocean may be affected.
We first filled three jars with water, vinegar and salt water and placed one clam shell and one scallop shell into the jars. We checked both the temperature and the pH of the water and after a few days we noticed that the container filled with vinegar was empty, both the clam and the scallop had dissolved. Not long after this the clam from the salt water had dissolved; the scallop in the salt water lost some of its color and became a faded brown color. We then tested how much weight the shells could hold we stacked books up onto the scallop and clam shells some held up more than twenty. This experiment shows that the acidity of different substances can cause a bad affect for the oceans sea life.
The Shells and pH experiment helps to show how the small things can have a bigger effect than you may think. The water, salt water and vinegar all showed how they could affect things differently. The shells for the experiment showed how in a matter of days the shells could be dissolved. Rebekah R.
Food Web Game
In biology, we played the food web game. Basically you choose to be one of four animals. Each animal needs a certain amount of food to survive. This is an important experiment because it is a fun way for students to understand what’s really going on in that environment.
There are two types of food to choose from; salps and krill. You roll a dye to see who goes first, then from there, you go clockwise. In each level (there are 3 levels) the amount of food declines. I found this demonstration to be extremely enlightening; it showed how different species would either have to move to a different food source, or they would die for lack of nutrients. It was a really eye-opening experience.
Doing this experiment really helped my class better understand the decline of food, and why it’s so important. I really recommend this experiment to anyone who has a tough time understanding this topic. I don’t think I personally need to repeat the experiment, as I did understand the purpose.
