HAPPY PLANET

BIODIVERSITY MAP

The students of 1st grade created a biodiversity map during their nature lessons. The children worked with pre-prepared maps, on which they glued pictures representing elements of nature characteristic of specific areas.

The maps included, among others:
• coniferous and deciduous trees,
• various species of animals living in the forest, meadow, water, and near humans,
• plants typical of specific environments.

While working on the project, the students learned about the diversity of organisms living in their surroundings and discovered that every part of nature is important and interconnected. The activity combined education and art, helping children develop observation skills, teamwork, and creativity.

The finished maps were presented in class and discussed together with the teacher.

TREE FESTIVAL in kindergarten

 

Tree Day Celebration –10^TH October in Poland

Students from grades 1–3 celebrated Tree Day, the main goal of which was to remind everyone how important trees are in our lives. During the activities, the children learned why we should care for nature and how we can protect the trees around us.

At the beginning, the students solved riddles about places where trees grow—they correctly guessed that these are the forest, the park, and the orchard. Next, they watched educational videos about how a tree grows and learned the structure of a tree—the teacher discussed parts such as the trunk, the crown, and the roots. The children also learned the difference between deciduous and coniferous trees.

During the discussion, the students reflected on why trees are so important. They now know that trees produce oxygen, clean the air, provide shelter for animals, offer shade, retain water in the soil, and make the world more beautiful with their colors.

There was also an artistic component:

● Grade 1 colored prepared drawings of trees.
● Grades 2 and 3 created posters of different tree species as well as posters under the theme “Why Are Trees Important?” The children colored, cut out, and glued leaves and fruits, and wrote short facts about the role of trees on cloud-shaped labels. The completed works were displayed in the school hallway.

To conclude, the students thought about what they can do to protect trees. Their ideas included planting new trees, taking care of those already growing, and explaining to others why trees are essential.

To conclude the celebration, the students planted a tree together on the school grounds. This shared activity not only helped beautify the school environment but also served as an important educational experience, fostering a sense of community and responsibility for the world around them.

 

Tree Day was filled with interesting facts, creative activities, and inspiring conversations. Thanks to such initiatives, students learn that caring for trees and nature is an important step toward a happier planet.

OBSERVATION OF FAUNA AND FLORA IN POLAND

Students from classes 2a and 3a took part in outdoor lessons under the theme “Observation of Local Fauna and Flora.” During a field trip around the nearby area, the children carefully observed the surrounding nature and recorded their findings on specially prepared worksheets. During the activity, the students also learned the meaning of the term biodiversity and discovered why it is so important for the natural environment. At the end, each group of students created their own “biodiversity map,” which summarized the knowledge they had gained and the observations they had collected. Thanks to these lessons, the children were able not only to develop their skills in attentive nature observation but also to form an attitude of responsibility for the environment.

LIFE CYCLE OF WASTE - POLAND

In class, we prepared a glass container, soil, and a selection of items: mandarin peels, a candy wrapper, a candy, leaves, a stick, pine needles, a seashell, a pear, cereal grains, a cardboard box, and a deceased grasshopper that the children had found during a walk. We placed layers of soil in the glass container and arranged the individual objects, covering them with additional soil. This activity was carried out on 30 September 2025.

On 4 November, we examined the changes that had occurred. It turned out that only the candy had disappeared; all the other items were still present. The grains had germinated. While observing the changes in the various types of waste, the students noticed an unpleasant smell, indicating the decomposition of natural materials. They also discovered a new living inhabitant in the container — an earthworm — which remained in the soil together with the other items.

In a month, we will check again to see what has changed and how our waste is “living.”

RECYCLING

In the lower grades, students participate in ecological education sessions dedicated to proper waste segregation. Children bring various types of waste from home, including plastic bottles, paper, cardboard, glass, and mixed waste.  At the beginning of the lessons, the principles of segregation and the colour-coded system of waste containers were reviewed. Working collaboratively, students then sorted the collected materials, placing each item into the appropriately designated container.

These sessions are highly practical in nature—students independently decide which container is suitable for a particular type of waste. During the activity, the most common segregation mistakes are discussed, along with the broader importance of responsible environmental behaviour. Through these lessons, students consolidate their understanding of recycling and the responsible handling of waste. They also gain awareness that their everyday choices and actions directly contribute to the protection of the natural environment.

 Experimental junior High School of Rhodes, University of the Aegen, Rhodes, Greece

Educational visit by the students of the Experimental Junior High School of Rhodes, University of the Aegean, to the Rhodes Butterfly Education Center for the Environment & Sustainability

On Wednesday, November 26, 2025, students from the Eco Club of the Experimental Junior High School of Rhodes – University of the Aegean made an educational visit to the Rhodes Butterfly Education Center for the Environment & Sustainability. The visit was part of the school's environmental education activities and aimed to raise students' awareness of issues related to the natural environment, water, and sustainable development. During their stay at the Environmental Center, the students learned about the Center's operation and role in promoting environmental education. Through a series of experiential games and educational quizzes, the children actively participated in exploring issues related to the natural environment, acquiring knowledge in a creative and enjoyable way. Particular emphasis was placed on the "World of Water" program, which included topics such as: the relationship between water and human needs and its invaluable importance, the concept of modern marine ecology, the distinction between fresh and salt water, the ecological footprint of food, and the water cycle. The students approached the topic not only from an environmental perspective but also from the perspective of active citizenship, exploring ways of responsible management of water resources. Outside the Environmental Center, the students had the opportunity to observe closely how solar panels work, how a botanical garden works, as well as a small wind turbine, which converts the kinetic energy of the wind into electricity, offering a practical example of renewable energy sources. Later, the group went to the Valley of the Butterflies, where they participated in activities at the Pelekanos stream. Using state-of-the-art binoculars, the students observed the natural landscape and took part in experiential activities that highlighted the richness and uniqueness of the area.

Learning how to make pH Measurements 

On December 10, 2025, in collaboration with the Physics teacher, we gathered at the Physics Laboratory of the Experimental High School of Rhodes, University of the Aegean. 
Initially, the students dealt with the basic distinction of materials into acidic, basic, and neutral. Through an experimental process, they used pH paper to measure the pH of various solutions, such as acids, bases, and water, in order to understand the concept of acidity and alkalinity. At the same time, substances of different acidity and basicity were compared, reinforcing the students' investigative approach and critical thinking.
Then, as part of the environmental investigation, the teachers brought in samples of seawater from different spots around the wider sea area of Rhodes. The students measured the pH of these samples and found that there were no significant deviations, as the values were within the normal limits for the marine environment.
The activity was completed with microscopic observation.The students used optical and electronic microscopes to observe microorganisms contained in seawater, gaining a direct picture of the microscopic life and biodiversity of the marine ecosystem of Rhodes.
The above activities contributed significantly to the understanding of basic concepts of Chemistry and Environmental Science, while at the same time raising students' awareness of issues related to the protection and conservation of the natural environment through experiential and experimental learning.

 

CREEPY CRAWLIES COMPETITION 

Under the Microscope – Discovering the Secrets of Leaves.

The lesson began with a short discussion linking the topic to the Happy Planet project, emphasizing that plants are the “lungs of the Earth” and introducing the importance of understanding their internal structure. Students then checked their workstations and prepared for the laboratory activity. During the main part of the lesson, the teacher demonstrated how to take a piece of the lower leaf epidermis, and students prepared their own slides using a drop of water and a cover slip. Under the microscope, they observed epidermal cells, stomata, and chlorophyll grains (if visible), documenting their observations with scientific drawings on their worksheets. The lesson concluded with a short presentation or discussion of the most interesting findings and the functions of the observed tissues.

 

Experiment with salt & importance of water

The experiment carried out by first-grade students focused on observing the process of salt crystallization. Warm water was poured into a jar and mixed with salt, and a few drops of food colouring were added. A string was attached to a stick placed across the top of the jar so that the end of the string was submerged in the solution, and the experiment was left for two weeks for observation. During the following days, the students noticed that the water slowly evaporated and colourful salt crystals began to appear on the string. Through this activity, the children learned about evaporation and crystallization, and also understood how important water is in nature and why we should protect it. The experiment encouraged curiosity about the natural world and showed that science helps us better understand the processes taking place on our planet.
