3. W HY DO L EAVES CHANGE THEIR COLOR IN THE FALL ?

4. L EAVES M AKING F OOD Leaves make food in the summer by using the sun light and turning it into sugar But in the fall the leaves have to survive off of the food that they had made in the summer How leaves make and use their food These leaves are starting to use up their food

5. So, as the leaves start using up all the food they begin to lose their bright green color The tree to the right is still green and the tree to the left is beginning to lose the green color

6. W HAT IS HAPPENING WHEN THE LEAVES CHANGE COLOR ? As the food in the leaves that has been made and stored over the summer gets used up by the leaves, the leaves begin to turn the brown color that we see when leaves fall off the trees.

7. D ID THE LEAVES ALWAYS HAVE THE COLORS WE SEE IN THE FALL ? Leaves have always had the red, orange, and yellow colors that we see in the fall But they don’t show until the fall because the green in the chlorophyll covers it up. Chlorophyll: the green coloring matter of leaves and plants, essential to the production of carbohydrates by photosynthesis As the leaves use up the energy that they have stored, the reds, yellows, and oranges of fall then begin to show.
