What is Energy?

Energy is the ability to do work. Two states of energy are kinetic energy and potential energy. Kinetic energy is energy of motion. Some examples of this would be electrical energy, radiant energy, thermal energy, motion energy, and sound energy. Potential energy is stored energy. Some examples of potential energy are chemical energy, stored mechanical energy, nuclear energy, and gravitational energy. Radiant energy can either be visible or invisible to the human eye. An example of radiant energy could be the sun's rays hitting Earth. Radiant energy is also known as solar energy. Gravitiational energy is energy that exists between two or more masses. An example of this could be an object falling off a high cliff or mountain. While studying the different forms of enegy, I learned that everything around us uses energy to work. This topic was interesting to learn about and I hope to learn more.

DNA Tests Help Parents Choose Sports For Kids

A recently discovered genetic test helps detect which sports are fit for your child to play. This test that costs $149 can judge the natural abilities a child has that helps the parents find a sport that the child is capable of playing. This test predicts the strengths a child has and which sport is right for that child's body. This DNA test is performed by simply swabbing the inside of a child's cheek and all along the gums. After that, the test is sent to a lab to be evaluated. When you get this test back, you can tell what strengths the child has and how much speed the child is capable of. This DNA test is said to predict less parental frustration for those who are having trouble finding sports right for their children. Therefore, I think this DNA test is a really cool genetic test that will really help parents find sports that are right for their children.

New Car Technology

Throughout the year, around 40,000 people are killed in car accidents due to either being careless or not having enough safety to protect themselves from other drivers. However, recently companies around the world advertised the future of cars at a convention in Manhattan. One of the cars that were displayed was the Mercedes-Benz. When CBS 2's Cindy Hsu took a ride in the car, she experienced a lot of protection during her ride. For example, in order to protect the passenger, windows would roll up, the sunroof would close if there was one, and seatbelts would tighten in order to protect the driver and passengers. Therefore, once these technologies are made for the cars, we would be saving countless lives of those who are in danger while on the road. By learning about this topic, I strongly come to agree that these technologies are important and should be available in cars to protect the passengers while driving. Safety comes first.

Producers,Consumers, and Decomposers

What are producers, consumers, and decomposers? These three terms indicate how an organism gets its energy and interacts with the other living things in its community. Producers are organisms that use a source of energy to make their own food. However, consumers are organisms that cannot make their own food. Therefore, they feed directly or indirectly on producers and depend on them for food and energy. In this category, there are three types of consumers. The three kinds are herbivores, carnivores, and omnivores. While herbivores only eat plants and leaves, carnivores only eat meat. However, the kind that eats both plants and meat is called an omnivore. Humans for example, are omnivores. Deers are herbivores and lions are carnivores. Besides producers and consumers, we also have decomposers in our ecosystem. Decomposers are organisms that break down dead matter into simpler substances. Bacteria and mold are two examples of decomposers. Also, along with breaking down dead matter, decomposers also start and end every food chain. In conclusion, producers, consumers, and decomposers are three terms that tell how different organisms obtain energy and interact with other living things in their community.

Enviornment and Habitat

What is your environment? First of all, environment is where an organism lives and obtains the needs for its survival. Your habitat also provides you with resources that you need to live in the given area. In a certain environment, there could a community or a population. Community is where all the different organisms live together in a given area where in a population, the same species, or same types of organisms live together. Aside from this, not many organisms can adapt to new habitats whereas humans can. An example of this would be that if an architect was to design a new home for the cheetahs in a zoo, then he would have to now the environment the cheetahs live in. Since the cheetahs cannot adapt to a new habitat, the architect would have to design a home with the resources found in their natural environment. After learning about environments and different habitats I am really interested in learning more. This topic was very pleasing and I hope to learn more about it.

Math is...

You may not know it, but we use math everyday to solve some of our problems. Whether it be getting into even groups to play a game, or timing how fast you do something. All of it is math.
Along with that, you can find math everywhere. It can be in number form and in word form. Math is full of different formulas and techniques in solving problems. The different techniques help you to see something differently if you don't get it one way. Therefore, math is everywhere around you even though you may not realize it.
