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! 😉
