Three months seem to have flown by in the blink of an eye and yet so many things have changed in that time. We began this project with very little information about what the end product would be and why we were doing it but we learned a lot along the way.
The purpose of the project was to make us think about what goes on in the sky over time. As it turned out, I was a slow starter. I work full-time and my regular lunch hour is from noon until one o 'clock, therefore making observations at 1:15 p.m. during the beginning of our semester was nearly impossible for me. However, over time my mindset and my methods changed and I eventually got smart and set an alarm on my phone to remind me to make the observations. As the old saying goes -

In addition to the shadow getting longer, the declination (or altitude) also changed during the course of our project. Beginning at approximately eleven degrees way back at the end of August and decreasing over time until the end of November when we see the declination at approximately negative twenty degrees. However, I also noticed a variance in the given data from my data of about three to four degrees. My calculations were taken in York and the given calculations were taken in Harrisburg. A question that I would have is whether the small distance and subsequent change in latitude between the observation points would explain the difference in declination or not.
The graph of the altitude measurements or declination is very helpful at showing
the steady decrease in the altitude of the Sun during the course of the project. My personal observations were not as clearly defined, however, when placing them on the graph with the given observations, the whole picture is clear.
The graph of the percentage change in declination did not turn out quite as well for
me. The calculations that I did with the given observations graphed quite nicely and stayed relatively in a line. Then I added my own observations and they pretty much went all over the graph. Based on feedback that I received earlier in the semester, I realize that some of my observations were not coming out correctly, so this may have

I found out that both of my experiments were off by 0.46 and 0.13 but were remotely
For many years astronomers and people alike have constantly heard about the observations and records of the Chinese and Europeans. No other culture can provide as much information as that gathered by the Chinese and Europeans, but there are many other cultures that observed and recorded the night sky, one of those being the Native Americans. During the last fifteen to twenty years archaeoastronomers have uncovered much concerning the beliefs and records of Native Americans. Unfortunately, the methods of keeping records of astronomical events were not as straight forward as the Chinese and Europeans. The Native Americans had to use what they could to record what they observed. Their records were found on rock
Observation one is carried out straight after the lunch time break and is during a 30 minute teacher lead whole class science activity investigating light sources. This links to The National Curriculum under Science, Physical Processes - Light and Sound, (DfES, 2004). KU1.4

If they do not, but are within the acceptable margin of error of ±20√4=±40’’, each angle is corrected to create a sum of 360˚. For this project, the angles added to 360˚ 00’ 10’’. After each angle is corrected, angle 412 is 78˚31’03’’, angle 123 is 99˚01’23’’, angle 234 is 92˚32’21’’, and angle 341 is 89˚53’13’’. After using the Total Station, the Auto level is used to measure the elevations of each point. The known elevation outside of Powell is 380’. The Auto level is placed between each point to measure the backsight and foresight. Once all the points are measured, all the backsights and foresights can be measured with the difference taken to find the error. With this project, the error was -0.128’. Next, the pacing between each point must be taken to find the correction for each elevation with the equation, (distance from known elevation/total level network distance) X total error. The total pacing for the project is 235 steps with a pace of 2.31 feet per step. After the corrections, point 4 is 379.384’, point 3 is 378.182’, point 2 is 379.093’, and point 1 is 379.645’. A transit is used to find the true north from the magnetic
Recording short and longer-term patterns of events that occur on Earth and in the sky, such as the appearance of the moon and stars at night, the weather and the seasons.
Use the elementary school textbooks you selected to complete the following table. You must review at least one textbook from each of the following three grade ranges: Grades K–2, Grades 3–5, and Grades 6–8.
The black line is so much more variable than the red line because the black line represents the annual average temperature and the red line represents the 5 year running average temperature.
Bruce Palmquist and I held for them. I was amazed by how captivated the young students were when the planetarium light was dimmed to make the dome pitch black. Their voices in awe are vividly engraved in my memories when the bright stars appeared all around them. As the stars appeared bright on the dome’s wall, I showed them how to find Polaris, and shared with them several Greco-Roman and Navaho stories about constellations. It was a rewarding experience. The students were happy to learn about constellations and stories about the stars, and when the show was over, the students were happy to have been inside the planetarium.
In conclusion, I chose this Citizens Science Project for my future classroom because of the benefits it will give my students. I believe that each student will be a scientist and will prepare them for observing higher education labs, without the intimidation that can happen to many students. This project will help scientists make predictions about natural disasters and weather patterns, while simultaneously helping boost my students’ confidence and interest in science and the world going on around

Since the first Egyptian farmers discovered the annual reappearance of Sirius just before dawn a few days before the yearly rising of the Nile, ancient civilizations around the Mediterranean have sought to explain the movements of the heavens as a sort of calendar to help guide them conduct earthly activities. Counting phases of the moon or observing the annual variations of day length could, after many years' collection of observations, serve as vital indicators for planting and harvesting times, safe or stormy season for sailing, or time to bring the flocks from winter to summer pastures. With our millennia of such observation behind us, we sometimes forget that seeing and recording anything less obvious than
