Project Overview

1. Description of Our Community

Our local communty is located in Romania , a Central European Country. Situated in the center of the depression with the same name, at an altitude of 360-380 m, Radauti has established its hearth in the confluence angle of Suceava with Sucevita. The oblong form of the dumps (NV-SE) favors the conduct of the wind blowing in this way, and the numerous water surfaces introduce some changes in the normal way of meteorological elements. The average annual temperature is 6.9°C; the average annual temperature of July is 18.2°C and of January -5.3°C. The average annual rainfall is 643.6mm. The clime is temperate. At first sight, an opened territory, the area of the town called Radauti is well hidden in a natural way, by the swampy land that surrounds it. This natural protection, associated with the vast possibilities of practicing the agriculture and cattle rising, have made Radauti, from the ancient times, an adequated place for living (the oldest signs found are from 7000 years ago). The first document that certifies the town dates from 1392, where Radauti was mentioned as the village of Radomir, making part of his properties, from which, as some versions say, it is supposed to have derived the name of the town. Other opinions say that the settlement has its origins in old times and the name “Radauti” comes from the latin word Rottacenum, given by the soldiers to name the roman garrison in Siret. Under slave influences we assist at a distortion of the original name Rottacenum and its conversion to Radauti, as it appears in later documents.

2. Summary of Our Project

Density is a physical quantity which represents the mass of the unity of volume. It shows us how much a cubic meter of substance weighs. In the international system of measurement, density is quantified in kg/m3. In day to day life, kg/m3 is used quite frequently. Water is part of the few bodies whose volume grows through solidification and thereby shrinks its density. At 0 degrees Celsius, water freezes, increasing its volume by 9%. The small value of density is due to the structure of the crystalized network. Because the density of ice is so much smaller than that of water, the water floats on the surface of the liquid. Normally, the density of a liquid decreases with the increase in temperature. Water has a different behavior between 0 and -4 degrees Celsius (nicknamed the anomaly of water). In this interval, the volume shrinks, and the density increases. The colder waters (which a higher density) can attract cold currents or can influence the climate. Moreover, the variables of density can affect the humidity of air and the formation of clouds. The changes of temperature of water influence local ecosystems, the vegetation, and the fauna. During winter, at the bottom of lakes there is water at 4+ degrees Celsius, which makes aquatic life possible. The local climate can change based on the changes of temperature of water and density, and in the long run, in the context of global warming.

3. Our Computer and Internet Access

A. Percentage of students using the Internet at home:more than 50%

B. Number of workstations with Internet access in the classroom:2-3

C. Connection speed used in the classroom:not sure

D. Number of years our classroom has been connected to the Internet:more than 6

4. Problems We Had To Overcome

Lack of time management.

5. Our Project Sound Bite

We got experience in working together and we learnt how to design a site better.

6. How did your activities and research for this CyberFair Project support standards, required coursework and curriculum standards?

We planned our site’s design before starting it, going through a lot of steps to make a result based off our ideas. This project helped us both in our ability to use different digital programms as well as learn more things about this topic. For strcturing our team work, he have divided the work based on what we were best at. This website helped us to understand better what we learn in school, and we believe that using the internet made our research easier, as it was accesible for all of us.

Project Elements

1) What information tools & technologies did you used to complete your CyberFair project?

We used both our personal devices and devices provided by our school. At home, it was easier and convenient to use our personal devices for creating the website, both on research and structuring the website and at school our teachers helped us on completing it, by providing to us their devices. We have also used books provided by our school library, in learning more about this topic. Overall, we found the most helpful our digital devices, as it made the creation of the website and structuring the information easier.

2) In what ways did you act as "ambassadors" and spokespersons for your CyberFair project both on-line and in person.

In the process of collecting information, we have contacted people interested in physics and computer science domain as well our school’s teachers to help us inform ourselves about the topic of the project and how to make the website containing it.

3) What has been the impact of your project on your community?

With the help of our project, we have helped our classmates from our class and other classes learn more about this theme, ”Density of water”, thus helping them understand them better through an user-friendly interface. Also, through the duration of making this project, we have made friends with one another and we learned more things together. In the end, the project was well appreciated by our school community.

4) How did your project involve other members of your community as helpers and volunteers?

We asked our friends, family and classmates if they have information about people who might be interested in taking part of the project, in the creation of the site or in informing themselves about this topic.

5) Discoveries, Lessons and Surprises (Optional)

During our research, we have discovered interesting things about how the density of water influences the nature.
