Why do most parents insist that one eat breakfast? And, what kinds of foods are eaten first thing in the mornings around the world? Using the data we collect let’s discover and celebrate a variety of breakfast foods.
Is your world noisy? Are some places louder than others? Does noise bother you? Can noise be a form of pollution? Let’s map noise levels and find out.
Travel to the heart of your community to discover the level of awareness of the importance to preserve bees in the ecosystem. Using provided questions, interview the experts about your island's flora and agricultural practices, and how they relate to the bee population; explore the data at a local and at a global levels using the data collected by your colleagues from different locations.
The goal of this project is to travel to the heart of your community to discover the level of awareness related to the importance of preserving bees in the ecosystem. It provides specific questions that you can make to experts on your island related to the flora and agricultural practices in the island, which you can then relate to the bee population status at a local and at a global level (through the data collected by your colleagues from different locations on Earth)
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?
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.
Sometimes people preserve fruits by adding water, sugar, and some spice to make a fruit preserve, and then putting the preserve in a tightly sealed jar. But when fruit preserves are stored in a warm place, they start fermenting, which is a chemical breakdown by microorganisms like bacteria, and they get sour. What does this process have in common with the souring of milk?
Berries differ by the amounts of sugar and organic acids, such as citric acid and ascorbic acid (vitamin C). Which type of berry is the most acidic? Is it true that the more sour a berry, the lower is its pH? Working together in this investigation, we will find out.
To avoid problems with your teeth or your health in general, the pH of tap water you drink should be close to neutral. But what is the actual pH of the tap water you drink? Does the pH of tap water change over the course of the day? Does it change day by day? Or after a large rainfall or snowstorm?
Every citrus fruit contains organic acids, such as citric acid and ascorbic acid, also known as vitamin C. Yet limes or lemons taste quite acidic while oranges or mandarins are on the sweet side. Which among citrus fruits is the "world champion" in acidity? Is there a correlation between acid taste and pH-levels? Are there variations in pH for the same citrus fruit grown in various countries, regions or climate zones. Those questions will be explored in this activity.
Today anyone can become a helper of the Earth. Help can only affair. And children can participate. Yes, Yes. Сhildren can help the planet. It is important that there was a desire to meet at the weekend with friends or with family and make something simple that requires no special costs and approvals, such that you just, their own, to act. After all, the future is coming in a minute. And, you see, well, if it was at this time somewhere on Earth plant trees, peacefully solve problems, clean up after themselves, help each other... Let such minutes, hours, days will be more. The project is supported by the Junior international organization "United by space".
How boring is sitting in the class! Today everything is like it was yesterday..., last week... last month... And if the lessons would be hold in museums - do you like the idea?
As we breathe, we exhale CO2. Can CO2 accumulate in closed environments like classrooms? Might air quality drop over the school day? Let’s find out.
Rarely do we take time to listen to how noisy our world can be. Stop and listen. What sounds do you hear? Day or night, quiet or loud, pleasant or abrasive - noise can be a form of pollution. Let's map noise levels and see what we discover.
Why do we like the sports we do? Does where we live impact our sports preferences? Is it our environments? Our cultures? Our friends? Our parents?
For many people on our planet the world is an everyday reality. We live under a peaceful blue sky, enjoy life, to dream of something more than the world and try to become a person in this large and imperfect world. However, for many people, the world is a dream or a fairy tale. Already at an early age, many children learn the meaning of war-blood, death, loss of loved ones, lack of funds to exist.
What do you do with used batteries? You don’t simply throw them away in the garbage do you? Please don’t do that! Recycle batteries correctly and join us in creating a map of hazardous waste drop-off centers.
“May there only be peaceful and cheerful Earth Days to come for our beautiful Spaceship Earth…” U.N. Secretary-General U Thant on March 21, 1971.
You will examine snow to determine what has fallen on it from the sky. You will prepare a report about what you find. You can compare your results with those of students at your school and other schools.
