Class Response: Frog Dissection





Recently in science class, we dissected frogs. I went into this completely disgusted by the idea and when I saw how big the frogs were, that didn't help. To make it even better, my table mate chose the largest frog with the most eggs. As the skin of the frog was opened up and the eggs were removed, my opinion on the dissection changed. The organs were so clear and it was so easy to tell what they were. I then realized why dissecting is so educational and why it is necessary; because the frog's systems are much more like a humans and by dissecting a frog, I received a better education on how frogs work and even how my body works as a human. I was really surprised by how much my take on the dissection changed. I would even recommend the dissection of frogs in future years but one thing I would change about the dissection is I would have less frogs used per class because it is sad that so many frogs are being killed. The one other problem with the dissection though was something that could not have really been changed and that was the smell of the frogs. All in all, the dissection was successful and a lot was learned from it.

Snowacane




Recently the northeast has experienced a "snowacane". The storm was called a "snowacane" because is was similar to a hurricane but was with snow. Both hurricanes and this snow storm started because of the low pressure system in the atmosphere. The storm was formed around Texas on Tuesday and began with light snow flurries. As it progressed, is became much more violent, and intense winds became part of the storm. A hurricane begins lightly and as it progresses it becomes much more violent and ferocious winds are added, just as they did to the "snowacane". The "snowacane" also included huge waves and flooding just as a hurricane does. The damaging flooding is the outcome of the snow melting and the torrential rains that were added to the storm. Flooding and rain is also a part of a hurricane. Just as after a hurricane is over, the "snowacane" left some places severely damaged. Some of these damages included flooding, dangerous ice, and damages on buildings and such, from winds. Some believe the cause of the storm was global climate change just as some blame global change for the higher number of hurricanes. Will the snow ever stop coming?
