A few weeks ago, my fellow peers and I went on a field trip to the Camden Aquarium. A few things I learned from this trip were: - How all the organisms behaved in their environment or habitat. - How these creatures interacted with each other. - The symbiosis relationships between animals that were put together (ex: the hippos and birds). - How these organisms rely on their resources in order to survive. - How some aspects are just a matter of the circle of life (ex: hippos eating fish). This trip was very exciting, fun, and educational all at once. I would reccommend and encourage anyone I can to go to the Camden Aquarium if they haven't done so already. Hopefully, anyone can have the same experience I did during the trip and enjoy and learn about everything I did. If I could I would love to go on this trip again. ~Vikinggirl15(:
In my Red science class, I conducted a radiation popcorn experiment. What i had to do was microwave popcorn. I know what your probably thinking which is that this has nothing to do with science whatsoever and that this is just a lame excuse to satisfy my hunger in science class but your wrong! This lab showed radiation and how heat is transferred with molecules. Radiation is the process in which air is heated and this process is the only way that the heat is transferred to move around in areas of space. Radiation causes molecules from the popcorn to vibrate and it moves the heat in the kernels which causes the popcorn to pop. The moisture in the popcorn kernels extend when the moisture inside the kernels get hot enough which makes them build up pressure transform into popcorn. In order for this to happen, there has to be a certain amount of heat in order for the popcorn to pop. This is how your favorite movie snack that seems simple is made. This proves that even the simplest aspects of life can deal with science. Next time you should ponder the simplest things in life and then you can see the nothing is actually simple.~Vikinggirl15<3>
In science class, we did a collapsing can lab which shows how air pressure has the power to crush a can so easy right before your eyes! When you heat the can half way filled with water, you cause the water to boil inside and turn into water vapor (which is a gas). Then this gas from the boiling water causes it to push all of the air out of the can. After putting the heated can filled with water vapor into a tub of ice cold water it will make the heated molecules cool instantly. When the can gets put into the water it makes the vapor condense and force all the air into the can to push all the air out. This makes the can get all scrunched up and close together in a flash. You may think this is magic but this is merely just science and the process of air pressure. :DD I recommend trying this at home because its easy to do and I enjoyed this experiment!~Vikinggirl<3
The Greenhouse effect article I read made me change my opinion about how important this is to the Earth. A few important facts I learned were: *The problems begin when human activities change the natural process by creating more greenhouse gases in the atmosphere than are necessary to warm the planet to an ideal temperature. *Scientists agree that even the smallest increase in the global climate would lead to significant climate and weather changes, affecting cloud cover, precipitation, wind patterns, the frequency of storms, and the length of seasons. *Many of the world’s endangered species would become extinct as rising temperatures changed their habitat.
This proves that WE are the ones who are causing the greenhouse effects that are occurring in the atmosphere. Therefore, we have to find a way to stop this before chaos breaks loose and the place that is now called Earth will turn into a disastrous place of havoc, destruction, and devastation! I was absolutely shocked when I read this article and now I just hope that the worse isn't going to happen and that Earth will still be able to sustain us and all the future generations that are yet to come. :0) ~Vikinggirl<3
In my red science class, we were given the assignment to dissect a frog. Personally, I felt that the dissection didn't seem so bad once we started exploring our frogs. The purpose of this assignment was to see the organs in the structure of the frog and to identify what each organ did for the frog. It seemed fairly easy to learn all the major functions and parts of a frog. Others may have hated this activity or thought that this assigment was intricate however, I thought it was way better than taking a written test on the frog. This dissection helped me learn about the frog and all of its systems and functions which gave me a better understanding of how the frog's body works. Hopefully, I will get the oppertunity to experiance dissections again so I can learn more about the major functions of other organisms. :D ~Vikinggirl15<3>
For the past two weeks or so, I have been learning about Sponges and Cnidarians in my science class. What I learned about these underwater animals are about their body structures, how they obtain food and oxygen, and how they reproduce. Here are some facts about each of these creatures: Sponges
Sponges are asymmetrical, which means they don't have any lines of symmetry. Sponges stay attached to a solid surface and they don't swim. Sponges obtain food and oxygen by filtering the water that flows through their bodies and taking the oxygen from that water. Sponges reproduce asexually (budding) and sexually. Sponges are invertebrate, which means that they don’t have a backbone. Sponges have spikes they use to protect their soft inner parts of their body.
Cnidarians are invertebrates. Cnidarians have two basic structures called medusa and polyp. Cnidarians have radial symmetry. Medusas are weak swimmers so they rely on water currents to move them. Polyps don’t move at all, they attach themselves to a solid surface. Cnidarians have stinging cells and tentacles that they use to capture and obtain their food. Cnidarians reproduce sexually and asexually.
In my opinion, I liked learning these intresting facts on these underwater creatures and I would like to learn more about them soon! ~Vikinggirl15<3
