Hello, guys! I am very excited to invite you to take part in my project "The coolest spot in your city". It is well-known that there are a lot of magnificent cities and towns in our country and all over the world. Each city is brilliant and unique! And I am sure that every person living in any city has a special spot where he enjoys spending his time. Share your fabulous wonders! Show us their beauty!
The nature is a living organism. It feels the pain. It can suffer just as we do. The humanity has been exploiting it for many centuries. We have always seen the nature as an inexhaustible well of sources only. But now we know that one day sources will be run out. Ruthless exploitation makes a great damage to the nature. Our growing appetite cannot be satisfied by it. We should develop new ways of using the sources. These ways lead to Eco Economy.
Batteries are labeled: do not throw into the dustbin. What to do with the used ones?
People like travelling, they do it a lot, as we live in a wonderful world full of different countries, beautiful cities, picturesque places, great monuments. Some travellers have visited most parts of the Globe and they can’t stop, they continue searching for something special. You are a manager of a travel agency and if you work hard, next year you will become the head of the agency. You want to have more people who will buy your tours. For that reason, you need to attract tourists including those who have been practically everywhere. What will you do to help you sell well? How will you attract travellers? Here, in this project you are going to create a virtual excursion to the most exciting parts of our Globe and be the first one among your rival agencies. Let’s see who will win and become the Head of the company!
What happens to unfinished soda? Many soft drinks are easy to tell apart by their tastes; they all are made from different recipes. But what they have in common is the presence of carbon dioxide. Compare the original acidity of soda with what happens to pH levels as the soda loses its carbonation and goes “flat”.
Fresh milk right from the cow has a pH value that is almost neutral. Gradually, however, milk becomes sour, even when it is stored in a refrigerator. In this investigation we will see if we can tell how many days old the milk is simply by measuring its pH. We will also investigate the microorganisms at work in its change in acidity.
