Why Do Leaves Change Color in Autumn?

Hi there! Today we are going to learn about the cool things that happen to leaves in autumn, the season that comes after summer!

1. Getting Ready for Winter: As autumn arrives, the weather starts to cool down, and this means that trees have to prepare for winter. In winter, there isn't as much sunlight or water. So, trees change and get ready!

2. Changing Colors: During autumn, the green leaves, which are filled with something called chlorophyll (that makes them green), start to disappear. When this happens, we can see other colors in the leaves, like red, orange, and yellow. These colors are always there, but we only see them when the green goes away!

3. Why Do Leaves Fall? When the trees know that winter is coming, they don't need their leaves anymore, so they let them go! This is a way to save energy and water. The leaves fall to the ground, making a beautiful carpet of colors!

4. What Happens Next? After the leaves fall, they will break down and turn into soil. This helps the tree get nutrients for the next spring when it will grow new leaves again.

5. Fun Activity: You can also collect different leaves outside and see their beautiful colors! Try to find leaves that are red, yellow, and brown!

Now you know why leaves change color in autumn and fall off the trees. Isn’t nature amazing?
