The space that air occupies is called the volume of air.

We put water in a large bowl and color it. Then we take a smaller bowl with paper inside (about halfway up) and place it upside down into the large bowl. We observe that the air inside the small bowl takes up space, so the paper does not get wet.

In our student webinar, we explored the fascinating world of science together! We conducted an experiment on the buoyancy of water to see which objects stay on top and which go to the bottom.

First, we made predictions about different items like stones, corks, and spoons. Then, we placed them in water one by one to see the results. We discovered that while some objects float, others sink depending on their weight and shape. Through this hands-on activity, we learned about the "pushing power" of water in a fun and interactive way!

The real magic happens when the children slowly pour vinegar into the shells. As soon as the liquid touches the powder, a chemical reaction occurs, creating carbon dioxide gas that foam up and bubbles over the rim. The result is a beautiful, fizzing eruption of colorful foam that mimics a real volcano on a tiny, egg-sized scale. It is a wonderful way for young learners to see science in action while exploring colors and textures.

Through our eTwinning project, we demonstrated that the language of science is universal. Little researchers shared the curiosity and excitement of discovery with their peers from another country, carrying out fascinating experiments live. This collaboration not only develops logical thinking, but also cultivates respect for diversity and team spirit at a European level.

Through this process, the children acquired important scientific thinking achievements, such as asking questions about topics they are curious about, describing the observed situations in detail, and establishing cause-and-effect relationships through a scientific process. At the same time, the students who presented and observed the experiment reinforced their skills in conducting simple experiments and talking about the results, while learning to transfer this knowledge into their daily life personal care and hygiene habits. This teamwork, carried out in groups, enabled the children to develop their cooperation, sharing, and communication skills by taking an active role in group activities, while maximizing their social-emotional values, such as feeling joy from working together and producing as a team.
