Soaring Straws

The lab soaring straws told me a lot about the relationship between elastic potential energy and gravitational potential energy. On our graph when the elastic potential energy was risen which was the stretch of the rubber band, the gravitational potential energy was also risen. This is because the further the rubber band was stretched was the higher that it went. For example, when we launched the rubber band from a two centimeter stretch, the straws gravitational potential energy was 2.943 millijoules. When we launched it from a three centimeter stretch it's G.P.E was 5.886 millijoules. From the stretch of the rubber band the height doubled. The G.P.E was the height that the straw went. That is the relationship between gravitational potential energy and elastic potential energy.

During our data collection there were a couple of errors that happened. First, when we were measuring our measurments they were not exact. Also, since we did it over two different days we got different launchers which mad different results. Ways to enhance the lab was to make every launcher the same. Some launchers shot very high but some did not. Usually, the thick rubber bands shot lower than the skinny ones. Also, we could have our measurments a lot more accurate because we could have made the ruler more steady and watch the hieght of the straw better. Finally, that is what the lab soaring straws taught me and how it can be a lot better.

“One Weird Watson”

Kenny
Intelligent, kind, and frightened
Who loves his family
Who feels worried about the Wool Pooh
Who needs a few good friends
Who shares dinosaurs with Rufus
Who fears the Wool Pooh
Who’d like to see his brother get punished for his crimes
Who dreams of losing his lazy eye

Who ends up being a member of “The Watson Pet Hospital”

Wool Pooh
Crazy, dangerous
Killing, torturing, swirling
Quick, powerful, slow, beautiful
Loving, soothing, relaxing
Calm, slow-moving

Toothpick Fish

The yellow fish are starting to be eaten and stand out. I am picking toothpicks from the cup and seeing what color the alleles would make my fish. As I was picking, the yellow fish were being eaten and taken away. A yellow fish could be made from a yellow and yellow "allele." If I picked a two red "alleles" it was red, a red and yellow "allele" the fish was orange, and any color with a green allele was green. The first time I picked the alleles, my population of fish went down one fish. The reason why this occurred was because I picked two yellow alleles which made a yellow fish. This is called an homozygous recessive, because I picked two recessive alleles. Through the next two generations I lost two more yellow fish and then a major event happened. All of the green fish could now not camouflage. Since the green fish was the most popular, that would mean that the population would now decrease a lot. I lost six fish which now left me with a total of 3 fish all together. If other fish could have camouflaged and not it would impact them and all the people around them.

The fish dying effects many people and animals in the ocean. The predators would not have a lot of food. They may get hungry and a lot of populations will decrease. This will also be bad for other people around them like humans. This will also effect the population of the fish because they can not reproduce if they are all dead. The only fish that can reproduce are the two red fish and the orange fish. There would be a lot more fish if the disaster about the green fish did not happen. They were the most popular fish. Also, it would be a lot different if there were a different amount of fish and the colors are different. This is the toothpick fish lab and how it impacts the ocean world if it were to happen.

New Species in Africa

Many scientists went on a field trip to Ethiopia and found what they thought they never would. It was a new species of an animal which people are calling an "African Wolf." Many people first thought that it was a golden jackal. They than realized that it had a lighter skin caoting and it was more thin. After days of research trying to find out what this species could be, they started to compare it to the Egyptian Jackal. This new wolf is a relative of the Holartic Grey Wolf which lives in Europe and Asia. The wolf that was found is rarely found in Ethiopia. It was proven it was not an Ethiopian Wolf because the new wolf splits from grey wolves later than Ethiopian Wolves. This wolf is also a relative of the Indian Wolf and the Himalayan Wolf. That is what the new African Wolf is and who it is related and compared to.

One Year Later

We all remember the devastating earthquake a year ago that struck Haiti. We were all wondering how they would recover from the disaster. They have recovered and are starting to make country better than ever. One of the main reasons how they are starting their comeback is a program called THREAD. THREAD basically means The Haitian Redevelopment Directive. This company will fix many problems which include poverty and trash. They will stop trash by paying Haiti's citizens to recycle. It will also provide "skilled jobs" for people in Haiti. Although it is going to cost thousands of dollars to help Haiti they believe that it can be done. The plan to rebuild Haiti will work but it is going to take a while before everything is back to normal in Haiti.

This is a picture I took at my friends house. It is a great example of mutualism. Mutualism is when both of the species benifit from their interactions. In this picture there is poison ivy on a tree. The reason why the poison ivy benifits is because it has a place to live. The tree is helped because it is protected by other animals. For example, if birds wanted to build a nest they would not build it in this tree because of poison ivy. That is just one example of mutualism in the world.

This is a tree in South Brunswick. It is a biotic figure which means that it is living. Another example of a biotic figure is grass, animals, plants, and many other things. There is also abiotic figures which are non-living. Examples of these are sunlight, temperature, clouds, and many other things.
