When the trees are actively growing they need a lot of food so that is why the. The chlorophyll breaks down the green color disappears and the yellow to orange colors become visible and give the leaves part of their fall splendor.

In the activity Falling for Leaves students make crayon rubbings of tree leaves then take a closer look to observe the characteristics of leaves in their own neighborhood.
This way when it gets colder and darker outside and they arent able to perform photosynthesis these plants can live off of the food they have stored. The trees use a bright green pigment called chlorophyll to absorb the sunlight they need through their leaves. In the winter there is not a lot of sunlight so deciduous trees and plants that lose their leaves in the fall trees begin to stop making food.

In this mini-lesson students discover how and why some tree leaves change color when the weather starts to get colder.
Darker red leaves are the result of a chemical change. I hope your kids will love this experiment as much as mine. Plants use a process called photosynthesis to get the energy they need to survive.
Inside a leaf there are many pigments but during the growing season these pigments are obscured by the green of the chlorophyll. Sugars that can get trapped in the leaves produce new pigments called anthocyanins that werent part of the leaf in the growing season. If the plants break down the chlorophyll and move it out of their leaves before the leaves fall plants save energy.
Every year kids are fascinated by the changing of the leaves in fall. The color change usually happens before the leaves fall off of the tree. The Chlorophyll fades causing the true color of the leaves to show.

As we know Chlorophyll gives leaves their green colour and is so dominant it hides the other colours in the leaves. But in the fall chlorophyll in the leaves breaks down allowing the other colours to finally shine through and show their beautiful reds yellows and oranges. Darker red leaves are the result of a chemical change.
Plants need water carbon dioxide and sunlight to produce their food called glucose. The lack of chlorophyll reveals yellow and orange pigments that were already in the leaves but masked during the warmer months. Why do leaves change color in Autumn.
