Climate Change and Marine Invertebrates English : Climate Change and Global Warming The concepts of “global warming” and “climate change” have become really popular and they affect the world in many ways. Passionate responses and heated debates between people to different views of the threat posed can be evoked by these subjects. Yet there are many things that are not well understood by the public when it comes to global warming, climate change, and the threats they represent. Generally speaking, climate change interests me because it is such an important subject because it affects the world and environment in which we live in. Global warming refers to the phenomenon of increasing surface temperatures of the Earth and Climate change is a change in climate patterns. What many people don't know is that climate is long-term weather, so it's over the course of hundreds of years. So if it rains a lot for 3 days and then it's sunny, that's not climate change. In the long run., global warming is mainly caused by greenhouse gases. Why? Because producing greenhouse gases acts as a thermal blanket for the earth. Certain gases in the atmosphere, like carbon dioxide, block heat from escaping. So the sun passes light through Earth's atmosphere and it warms the temperature and this heat is radiated back towards space. But what happens it that most of the outgoing heat is absorbed by greenhouse gas molecules so that heat gets trapped. And what that does it warm the surface of the Earth. Most of these greenhouse gases are carbon dioxide methane nitrous oxide and water vapour. The affects caused are warmer temperature, melting ice, increases sea level, ocean acidification and more. To conclude, I found this topic very interesting and I learned many cool new things about climate change. Because this is such an important topic, I just had to write about. I loved learning about how this affects the world around us and I will share this with some of my family to educate them on this. So, all in all, I found this topic very interesting. Math: pH Levels lab: So after we were done learning about climate change we did labs based on ocean acidification. In my group we measured the pH levels of the ocean and what this does is tell you how acidic the water is. The scale goes from 0-14. 0 being acidic, 7 being neutral, and 14 being basic. So what we did was add different solutions like vinegar and baking soda to fresh and sea water and see how that affected the pH.
Science: In our experimental marine biology lab we got to come up with a new hypothesis , make an experiment and actually do it. So I'm gonna show the experiment.
Career: Marine Biologist A marine biologist is someone who studies all types of creatures of the sea. They can study large animals such as whales and also microscopic ones such as plankton. What they do on a typical day or a day to day basis can vary because there are so many subjects they can focus on. A day can span from diving on delightful and amazing reefs; taking samples of the ocean from boats and then looking at them in the laboratory. You could even be teaching like undergraduates. Most marine biologists work regular hours in labs and use specialized equipment. They also may have to travel. The average salary for a marine biologist is around $50, 000. In order to become a marine biologist they need at least a bachelor's degree for entry-level jobs, a master's degree for higher-paying ones, teaching or research jobs, and a PhD. for teaching at the postsecondary level and for most research jobs. The fields they need degrees in are marine biology and other biological sciences, for example, zoology, ecology, and etc. So become a marine biologist requires lots of hard work put the work and research seems really interesting. Social Studies Map:
At the whale lab our marine invertebrates lab took place and in the lower lab which is the main building is where our climate change lab took place. These are what interested me through the field trip. Also at the docks there were ropes we could pull and I saw a whole lot of invertebrates there. We also measure salinity and collected plankton at Grappler Inlet. Moving on to the second map, on Aguilar point I saw a whole lot of anemones and observed them there. I also saw them eat hermit crabs which was pretty interesting. How the Scales work It's pretty straight forward how the scales work so basically you measure the line and the value beside the line is what that length equals. So for example on the first map, that line is approximately 1.75 cm. So that means 1.75 centimetres approximately equals 50 metres on the map.
