'; Fanny Keisala | Flekke Glocal
I am a 16-year old student from Finland and Switzerland, now studying in United World College Red Cross Nordic in Flekke, Norway.
My challenge
Learning one concept or system from the nature per day, for example how the leaves change colors ...

Day 28:

  • Why do we have freckles?

Our skin contains melanin, a protein that protects us from the ultraviolet radiation of the sun. Some people have it spread evenly on there body, some have it in clumps, these clumps are called freckles.

Melanin consists of celles called melanocytes, that reflect and darken the damaginf UV-rays. Freckles are genetic, both red hair and freckles are often related to the same gene MC1R.

Day 22:

I have been wondering why these different shapes and lines (in the picture above)  appear on the surface of the fjord. Me and my friends have guessed its probably because of underwater currents, the wind etc. We were not too far from the answer, which was that it is fresh water that forms these currents. Fresh water descends  from the mountains and ends up in the salty fjord water. These two do not mix together and so fresh water currents end up going around and you can see them on the surface as darker lines.

It is funny how I have been wondering about these water currents since the first day I saw them on campus. I never bothered asking other students or teachers about it. It doesn’t take long to obtain an answer either by asking or by researching. After the challenge is ovet, I might not try to find questions daily, but every time I do wonder about something, I will make sure to figure it out! 🙂 

Day 9:

More than a week of challenge down, I have already learned plenty of new things. 🙂 Why does it rain so much here in Flekke, can I plant an apple tree from a single seed, how does water reflect the sky… My favourite one so far is why/how do leaves change colour and fall off. Here’s why. Because of the changes in temperature and amount of sunlight, the trees stop their food-making process. This makes the chlorophyll (biomolecule that absorbs energy from sunlight and gives leaves their green colour) break down into smaller molecules. This makes other pigments, like red and orange, appear. 

In the fall trees stop their food-making process and reduce themselves to only trunks and branches. By dropping their leaves, they save energy. Trees that lose their leaves part of the year are called “deciduous trees”. 

We’ve had a couple sunny days this week,  and I have walked around enjoying the colourful leaves and the fresh autumn weather. This challenge has made me more curious on my surroundings. Some questions have surprisingly simple, some surprisingly complicated answers. My goal this week is to think a little more outside the box and come up with new interesting questions! 😀

P.S I linked a video in case my explanation of the leave process was unclear! 😉

Day -1:

  • So the challenge starts tomorrow, and I have prepared a notebook to write my new discoveries on the nature and its behavior. I hope that by the end of these 30 days I am more aware of how the environment around me actually functions and feel like I can understand it! 🙂
