Introduction For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.
Therefore, the linear shape of the rigid body rotation curve demonstrated that the curve was a solid body rotation. In the second activity, I completed the table by determining the speed of the planets in the solar system. The table included the planets,
Gravity is caused by the penetration of the centers of the sun and planets without any diminution, according to Sir Isaac Newton. Francis Bacon, English philosopher of science, believes that science make little progress because there isn’t a specific goal sciences just keep providing new discoveries.
Although the book contains a massive amount of words, there is one thing in particular that stands out to me and that is, pictures. For a 32 paged book about the Solar System; you would think there would be word after word, but its not the case in this book. In every page of the book there are small graphics explaining how new planets are found, how stars are made, etc. “Five planets formed in the cooler, outer part of the disk-- Jupiter, Saturn, Uranus, Neptune, and Pluto are formed from the lumps of ice and freezing gas found there” (8 Kerrod). Kerrod shows 2 graphics explaining how each planet is formed and where it is found in our Solar System.
The Wastelands is segregated with species from hundreds of Realm Worlds and rival nations. These uniform militias employ their home world technologies to fortify their kingdoms from feuding enemies. Ruled under a totalitarian dictatorship they often launch campaigns against neighboring kingdoms resorting to guerrilla warfare tactics. Once the kingdom is toppled the captors are systematically enslaved consequently expanding their future reign. Several are capable of traveling to their worlds through the use of Realm Portals.
I also used the H-R diagram to describe the position of the stars. For instance, as I changed the temperature of the star, I realized star 1 moves closer to star 2 as the temperature decreased. In addition, I understood how the star's mass effects the system period. For example, as the mass decreases, the system period increases.
Other scientists like Nicolas Copernicus believed in the Heliocentric Theory. At first, it didn’t explain how the planets orbits the way they did and was very hesitant to share it with others. In 1601, another scientist named Johannes Kepler proved that Copernicus idea was correct. They show that the planets rotate around the sun. Another method Copernicus, Kepler, and Galileo developed was called the Scientific Method.
During the Middle Ages a Roman Astronomer named Ptolemy came up with the theory that all surrounding planets orbited around the Earth. Advancement in telescopes and technology helped Copernicus during the renaissance create a more logical and accurate theory which stated how the sun is in the middle of our universe and all planets orbited the sun. This changed the way man thought because it realized how small Earth is compared to the rest of the solar system and how we may not be
As the data suggests (assuming no errors were made during the measurement process), the angular separation between Jupiter and Spica grew slowly from 10 degrees to 11 degrees (approximate numbers), then shrank back down to 10 degrees towards the end of the semester. However, the angular separation between Jupiter and Arcturus seems to increase over the course of the summer and did not make a return (at least dramatic enough to be noticed like Jupiter and Spica) to its original separation (consulting the Starry Night software after the experiment confirms that the angular separation between Jupiter and Arcturus was indeed slowly decreases). Question 12: Over the course of the summer, Jupiter was getting dimmer. This can be attributed to the
Comprising 45 percent of the sun’s radius, the radiative zone extends outward from the core, and the energy from the core is carried outwards by photons. A photon travels around one micron (one millionth of a metre) as it is made, before being absorbed by a gas molecule. As it is being absorbed, the gas molecule heats up and re-emits another photon of the same wavelength. This exact cycle is repeated once the re-emitted photon travels another micron before being absorbed by another gas molecule. Before a photon reaches the surface, about 1025 absorptions and re-emissions take place, which means there is a significant time delay between a photon made in the core and one that reaches the surface.
Whenever I look up at the night sky, I can see the stars that are just visible enough for me to see as a small dot. I look up at the stars wondering if they are galaxies, stars, or even planets. Whatever those stars may be I see them as opportunities, opportunities for us to see and explore. However, they aren’t the only stars that can be seen as opportunities. The stars that are drawn on paper can also be seen as opportunities.
Throughout units one through six, there have been many interesting topics such as the Antikythera Mechanism, Charlemagne , the fall of the Roman Empire, and my favorite; the Bayeux Tapestry! The Antikythera Mechanism was the Greek’s guide to the universe! This complex device, created in Greece during 100 BC was used to show the position of the sun and the moon and even eclipses! The sky was of interest and by tracking the moons phases and eclipses, the Greeks saw more significant, successful harvests.
Their efforts did not produce change because the motions of the sun and the moon were not measured accurately. Copernicus’ calculations of the motions of the sun and the moon were satisfactory to their needed
Gravity has impacted our solar systems in many ways from shaping it’s formation, the motion of each planet, asteroid, and other celestial object’s orbits, and is in fact the glue that holds it together all of this together -- Knowing this has helped many scientists in the past and it will in future discoveries and observations. As said before gravity has impacted the formation of our solar system and with the given evidence I will say how. Gravity in many ways has shaped and formed our solar system. An example would be the shape of the solar system’s celestial bodies’ orbit. They are in a circular orbit (though the sun is not in the center making it look a bit elliptical) and this is because of the sun’s gravitational force pulling on each
Today virtually every child grows up learning that the Earth orbits the Sun, but four centuries ago the heliocentric solar system, where the Earth orbits the Sun, was so controversial that the Catholic Church classified it as a crime of heresy (UCLA). In the age of early philosophy, Socrates’ is well known. Between the Socratic method and his line of successful students, Socrates’ makes the history books. Galileo Galilei turned astronomers on their heads when he discovered moons around Jupiter. Giordano Bruno didn’t back down from any of his brilliant and different ideas.
