M Hodža´s Grammar school, Liptovský Mikuláš, Slovakia. Then we found out information about our trees and marked 4 leaves on their branches. We regularly observed the colour change of marked leaves and entered data in Green Down Protocol. We experimented with leaf pigments and tried to understand why and how the leaves change their colour in autumn. We have learned much about nature and spent a nice time together.

Quick warning
This study helps people understand nature and its biological life cycles.

That's why students from this school decided to dedicate themselves to the sake of this study. I'm telling you that once you start reading, you won't be able to stop.

Many people might think this is a boring study, but we have children from all over the world who prove those people wrong.

Here we have students from the middle school ''Petar Pop Arsov". They will explain what phenology means to them.

- 'At first, I thought that this study was going to be very boring. Turns out I was wrong. It's extremely interesting, and you get to learn many things about trees and leaves. And not only that but also how the seasons influence the color and strength of the leaf.' - Matea S.

- 'This is such an amazing study. The moment my teacher mentioned nature, I was instantly sold. It's truly something you mustn't take for granted.' - Jana K.

These are just some of the many students that participate in this activity.

If you would like to know what they do to the leaves and trees, turn to the next page, and who knows maybe you would like to join them.

Which tree did we pick?

This adventure started when our English and Biology teachers introduced this activity to us, explaining how it all works.

While listening to my teachers, I was daydreaming about all of the fun and exciting journeys I could have with my friends.

So my two best friends joined this group and started working immediately.

There were a few beginning steps before the actual observation. First, we had to find a tree, then we had to pick out four leaves for which we had to collect data and put that data into a table.

For each leaf, we had to put what day we checked it, what colour it was, has it had fallen, if was it still attached to the branch and so on.

We had to check each leaf twice a week for four weeks.

Come and see how our last month was spent.

We decided to pick a tree that was located behind our school. A big, tall walnut tree full of branches and a lot of leaves.

If you didn't know, the scientific name of the walnut tree is Juglans regia or just Juglans.

The height of this tree is about 16 meters (53 feet) tall. Trust us it's very tall.

When and how did we start?

Me and my best friends started doing this research on the 9th of October. We learned many things about the trees and the leaves. It was really interesting.

Let's see all the weeks in a few pages!

The first week on Monday 9th of October at 11 AM we started by marking 4 leaves with ribbons. After we marked the leaves with ribbons, we took the color guide and placed it on one leaf and then another until the last leaf.

The first leaf that we marked with a blue ribbon was the color 5GY 4/8 and the name is Verdun green. The second leaf was marked with a red ribbon, and it was the color 5GY 5/10 or Green-Yellow. The third leaf we marked with a yellow ribbon and it was 5GY 4/8 or Verdun green as the first leaf.

The fourth and last leaf was marked by a pink ribbon and the color was 5GY 5/10 or Green-Yellow like the second leaf.

Then we checked back on the leaves after two days on Thursday 12th of October at 1 PM. The first leaf this time was 5GY 5/10. The second leaf was still the same color as the first time we checked. The third leaf was lighter this time it was 5GY 6/10 or by the name Limeade, and the fourth leaf was also lighter, and the same color.

The first week of checking the color change of the leaves went by very fast.

Second and third week!

In the second week, the weather was very bad, it was raining almost all the time, but to a surprise, our four leaves survived the harsh weather and all of the ribbons stayed on the leaves.

The leaves were very good-looking and hard. Their color changed a little bit, and now it was 5GY 7/12 a very nice shade of green.

Then, we wrote the data in a table and took pictures of the tree and the leaves. The same procedure was followed the next week (the third week), except that the leaves had a very different color. Here, the leaves were starting to change. They had a more yellowish color than before when they had a vibrant and refreshing green color. Also, they were a little softer and smoother. But not all of the leaves were the same. Two of the leaves, the leaves that were more exposed to the sun were brighter than the other two, with the color number 2.5Y 8/12.

The other two darker leaves had the color number 7.5YR 6/4 and they were under the shadow of the other leaves that blocked their path to the sun's rays.

PHENOLOGY PROCESS AND LEAF PICKING

Pictures taken by Hana, Jana and, Matea

The fourth week started on the 30th of October. This day was very shocking for all of us. The first two leaves went from the color 2.5YR 8/12 to 7.5YR 6/4, and the other two which had the color 7.5YR 6/4 have now fallen on the ground. They were almost rotten from the rain since it was raining a lot that week.

Truly we were a little sad for the leaves. We felt like we'd been with them from the start of their lives, and now we were a part of their end.

We put the data in the tables and went back to class.

The last day came. The 2nd of November. We were very nervous to check the remaining two leaves because we were scared that they didn't make it.

We came to tree and none of us dared to look at the branch. One of my friends gained the courage and looked towards the leaves.

- 'Good news and bad news' - said my friend. We looked towards the tree and there it was. One single leaf with a ribbon was hanging for dear life. Now its color was 7.5YR 6/4. Sadly, the other leaf was on the ground with the color 2.5R 4/2.

Table made by Hana,Jana and Matea

This was the last day of our little journey. The last day of the four leaves who tried to survive this horrible weather. We know that they're just leaves, and none of us ever cared about fallen, rotten or moldy leaves.
But this study isn't only about putting data into a table, it's about respect towards unliving things, and the fact that everything has to come to an end.
We loved doing this activity, and we hope we will have an opportunity to do it again.
And we're going to tell you a little secret, even after this project was done, we kept on checking the leaf, and we were with it until its very last day.

Once upon a time, there was a magical tree. It grew near the kindergarten in Trnsko. It was magical because all the animals wanted to land on it. It had various branches and colors. A man passing by the tree was so amazed that he called his brothers, godparents, family, and friends. They wanted to take it home, but the children wouldn't allow it. Then, the animals landed and started singing to hypnotize people, preventing them from cutting down the tree. When the people left, all the animals rejoiced because the tree continued to live. The tree was very grateful.

Using leaves they collected while walking and getting to know the nature around our garden, they adorn and create various hairstyles for drawn characters. They spend a considerable amount of time on this activity, exchanging experiences and ideas, learning to listen to others, and accepting their ideas.

In our daily activities, we also incorporate a tactile box. Inside, various leaf textures await - fresh, dry, and by reaching in, they must determine the leaf's shape, color, and even its scent. This multi-sensory experience enhances their learning journey, allowing them to explore and appreciate nature through a variety of senses.

Children take great pleasure in visiting the trees we observe in our phenological campaign and noting the changes in leaf color. They use colored chalk to outline various leaf shapes and combine colors they have seen and find interesting for the leaves. This activity allows them to practice fine motor skills, enhance visual perception, strengthen their individual competencies, and nurture social interactions within the group.

Following their observations of real trees, the children embarked on a creative endeavor, fashioning tree models from non-pedagogically shaped materials and natural elements. Engaging in a phenological campaign, they displayed heightened attention to intricate details, the visual aesthetics, leaf shapes, and colors. This hands-on experience allowed them to deepen their connection with the natural world, fostering a keen sense of observation and a profound appreciation for the beauty of nature.

We want to share an exciting experience from our Trnsko nursery this autumn! A group of 26 cheerful children and two dedicated educators decided to participate in the phenological campaign. Our focus is on the plants Betula pendula and Tilia platyphillos, and we'll tell you what we've learned so far.
Betula pendula, more commonly known as silver birch, represents an interesting and recognizable species of tree easily identified by its white bark. Our children were delighted to study the leaves of this plant and compare their changes as time passed. Given the phenological campaign, we paid special attention to the onset of leaf fall and the color changes of the leaves during autumn. First observation leaves: 1. 5GY 5/10 2. 5GY 5/10 3. 5GY 5/10  4. 5GY 5/10
We also have the opportunity to observe Tilia platyphillos, known as the large-leaved linden, which is also an interesting and valuable plant. First observation leaves: 1. 5GY 4/8 2. 5GY 4/8 3. 5GY 4/8  4. 5GY 4/8

GrowApp GrowApp was launched by GLOBE Netherlands and partners as a part of the GLOBE European Phenology Campaign. The app allows you tо make animations of your tree by taking pictures with your smartphone. The app directly transforms these pictures into a time-lapse movie that shows changes over the seasons and even over the years. / GrowApp е лансиран од GLOBE Холандија и партнерите како дел од европската кампања за фенологија GLOBE. Апликацијата ви овозможува да правите анимации на вашето избрано дрво со фотографирање од вашиот паметен телефон. Апликацијата директно ги трансформира овие слики во филм со видливо време кој ги прикажува промените во текот на сезоните, па дури и со текот на годините. Why GrowApp? The GrowApp can be used as an addition to GLOBE data collection. It is great to observe the Green Up and Green Down process with GLOBE protocols and at the same time make a beautiful time-lapse movie of the tree. While having fun making an animation of their backyard, you will help scientists better understand climate change impact on the environment. / Зошто GrowApp? GrowApp може да се користи како додаток на собирањето податоци на GLOBE. Одлично е да се набљудува процесот на раснење и опаѓање на лисја со протоколите GLOBE и во исто време да се направи прекрасен филм со временски промени на дрвото. Додека се забавуваме правејќи анимација од училишниот двор, ќе им помогнете на научниците подобро да го разберат влијанието на климатските промени врз животната средина.
