Dr. Jason West presented Isoscapes: the spatial fingerprints of the biology of the Earth’s chemistry. Isoscape is actually a word that he made up to encompass the entirety of what he studies. Basically what this is the subject of the percent abundance of certain isotopes as it pertains to a specific geographic location. This percent abundance will be different depending upon the location of the sample. Isotopes are variations of elements due to differing atomic masses due to altering numbers of neutron in the nucleus. Isotopes chemically behave almost identically, but the keyword in this statement is almost. For example, hydrogen 2 diffuses slightly slower than hydrogen 1 which can make a difference when considering the atmosphere because this …show more content…
In my previous chemistry experience, isotopes had never been given a significant amount of attention. I was under the false impression that there was no true value to investigating them. This presentation corrected my previous view. They actually behave chemically different which leaves lasting effects on our environment. These differences can help us in forensic endeavors, product verification, and many other previous undiscovered ways. While I greatly enjoyed this presentation, I found myself lost a couple of times, unsure of what he was actually talking about. Topics that I had no previous exposure to such as fractionation and C4 plants had me playing catch up during the presentation trying to be sure I was coming to the right conclusions. To prevent this from occurring, I would have enjoyed a presentation on what we were currently learning and its application in the real world of science. Having a presentation on something such as recycling, ocean acidification, or combustion would have resonated better with me. However, I did enjoy this presentation and Dr. West did a fantastic job of simplifying this concept so I would be able to
Answer. The isothermal shift is much more pronounced in high altitudes than in low and also much more pronounced over the continents than over the oceans. (Hess, 2011, p.90). The temperature gradient (rate of temperature change with horizontal distance) is steeper in winter than in
The fear’s very existence is caused by the lack of easy-to-access chemistry information for the public. Much of the knowledge the average American receives on a daily basis is through coverage in popular culture, and chemistry is simply not mentioned as often as the two other major sciences, biology and physics, on a daily basis. In fact, the only direct relationship most Americans have with chemistry is in a high school lab. A survey by the Royal Chemical Society, the oldest non-profit chemistry society in the world boasting a membership of over 50,000, found “the two most common words adults associate with the word “chemistry” are “school” and “teacher.” Once a person ends their formal schooling, however, they rarely learn more about chemistry in a professional environment. Despite being just as, if not less, dangerous than biology and physics, chemistry is not feared as much by the public because it is not mentioned in everyday life as often as the other two sciences. When the European Space Agency’s Philae lander made contact with the comet 67P/Churyumov-Gerasimenko, the world watched in awe as a human invention made contact with a comet for the first time, an incredible achievement in the world of physics and astronomy. However, there was no attention given to the fact that the sole purpose of the Philae lander was to fix a chemistry lab to the surface of 67P. It is no wonder why physics took the
1The isopods will gather in the wetter environment instead of the dry environment. 2The isopods will have an affinity to a more basic region than an acidic region. 3The isopods will tend to gather in the environment with a greater amount of light, than an environment with no light. 4The isopods will take a liking to a warmer temperature environment than a cooler temperature environment.By looking at the data you can see that there is a preference among isopods to favor an environment that is cold, wet, basic, and dark. We included the observed data as well as the expected data. Our expected data show what the information would look like if it came from a null universe. To come from a null universe means that the data will have no difference,
Please, Elene maybe we can put some of the information in the notes, since the slides text is very long?
Content selection should be abreast with knowledge of audience expected from the scientific presentation. Each slide should be self-contained and must not require external support for understanding. There are two ways to cut down presentation time: Visual is worth a thousand words and helps saving time for explaining in depth details of a project especially numerical data. One should put applicable content on slides because what matters most is the amount of information you caused to be absorbed by attendee. The Q&A is significant, the audience must gain freedom to engage with speaker and ask questions for better perspective of the talk. Contents should reflect critical analysis of evidences supported by research findings. Furthermore, Credibility can be established through what audience perceive by the presenter’s evidence.
Growing up in suburban Detroit, David Hahn was fascinated by science. He often conducted experiments in his basement and enjoyed making things such as homemade fireworks, brewing moonshine, and even making his own self-tanning lotion. Hahn especially loved chemistry and spent much of his time doing amateur chemistry experiments. The chemical reactions in these experiments sometimes went wrong and resulted in small explosions. We learned about chemical reactions in class this semester. He loved to read “The Golden Book of Chemistry Experiments” that his father had given him and tried to collect samples of every element in the periodic table, including the radioactive ones. We learned in class about the elements in the periodic table and how they are identified.
I did not find anything in the lecture particularly surprising. However, I do find it interesting the relationship wavelengths have with matter. I find it interesting that each element emits certain wavelengths that are unique to that element and how particular wavelengths of light are absorbed by matter.
Overall I think are presentation was good the reason why I think that is. Are presentation was about the apollo missions one through eleven and what each objective was for each mission. Each mission was an important role for nasa because they learned many things like the mistakes they made and the new things they discovered throughout the missions. It's fascinating how much they were able to achieve in a short period of time.
Our group decided on the science understanding of chemical science as our theme through strong influence from the Victorian Curriculum, as we adapted our unit of work to focus on the ‘Three States of Matter’ that centred around looking specifically at solids, liquids and gases in detail. We thought that this unit topic would be a fun and interesting to plan and create a sequence of six lessons with student-centred and hands-on activities throughout. I felt our presentation went informative in the sense of highlighting and addressing all our Victorian Curriculum components, although instead of just reading out all the content descriptors it would have been more beneficial to just focus and pinpoint how it relates, and how it was incorporated
Higher altitudes are cooler than lower altitudes, which is explained by the lapse rate. On local scales, temperature differences can occur because different surfaces (such as oceans, forests, ice sheets, or man-made objects) have differing physical characteristics such as reflectivity, roughness, or moisture content.
Dr. La Gerche gave an overall capable speech. His PowerPoint was well put together. It used dark colors that displayed well on screen and didn’t have paragraphs of text. The graphics were extremely effective some were
As fellow students and buddies Sam and I are fully (and painfully) aware of how difficult and troubled this presentation has been for some of you. We are really sorry for that, and although things might not have work out the expected way. I am sure the people in charge of this module have done its best to correct any immediate problems and to learn from this presentation to make it better for the future.
Presentations should reflect a careful analysis of audience interest and be relevant. Presentations should also reflect the theory we
The native american presentation that happened in class was quite informative. The things that one might learne were quite interesting. For example, the stereotype slide was informative. One seeing the peter pan part may be genuinely confused as to if they were singing or worshiping Cthulhu. Another part that was informative was the video about the treaties. The original treaty, the Two Row Wampum belt, was particularly interesting because it is a treaty and symbolic. The Iroquois confederacy segment was equally fascinating, as it explains a possible origin of democracy in America. Those are some of the many pieces of information in the native american slideshow.
The science presenter of the seminar is Greg Foot, he studied Natural Sciences at Cambridge and then he did a Master degree in Science Communication, the video was published on the Royal Society of Chemistry in March 11 2016.
