Air Pressure_ Collapsing Can Lab (10pts) :D

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_Respond (15pts) :)

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

Class Response- Frog Dissection O.o

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>

Class Response Blog #4 :]

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

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

Here are some links to some pictures of cnidarians and sponges: (:

This podcast talks about the awesome job of food and flavor chemists and everything you need to know such as the job description, salary range, why this career is exciting and useful and much more! Enjoy!

Science Class Response Blog- The Cork Experiment :]

Just recently in my science class, we did an experiment where we had to use vinegar and baking soda to make a cork shoot across the room to hit our classroom window. Although this may sound easy to do however, it really isn't. The reason for that is because if you don't do one thing correctly, you won't be able to hit the window which was what kept happening to my group. What happened was that my group couldn't do this procedure correctly which made us uncapable to hitting the window. We were so close a few times however, we couldn't hit the window. Even though we didn't hit the window, we still learned how to collect data and how chemical reactions form. In my opinion, I felt that that experiment was a fun way to learn about chemical reactions and that its more fun than just completing worksheets on chemical reactions. Hopefully, we can do more experiments like this one instead of completing worksheets and wasting paper. :)~vikinggirl15<3

Blog #2 Current Event :)

Did you know that there are only four specimens of the Yangtze giant softshell turtles left on Earth? Well there is, one in the wild and three in captivity. Now conservation partners from different societies are trying to save this species. On May 5th, 2008, turtle biologists, veterinarians, and zoo staff from different organizations came up with a plan to save the entire species. Their plan was to transport the turtles in order for the turtles to start a reproductive cycle and save the whole species from extinction. Yangtze giant softshell turtles are the most critically endangered species of turtles in the world and extinction risk is higher than ever! In my opinion, I think that this is a serious matter for the Yangtze giant softshell turtles and I hope that eventually, the population of these turtles will increase and become normal again. Also, I hope that in the future, these turtles will become a specie that will last a long time before they become extinct for good. ~Vikinggirl15<3
