2 hours and 30 minutes. Some leaves even have stuff in common with vegetables. That means that a tree changing much earlier than those around it is breaking down chlorophyll faster than it is being manufactured.

In the spring many plants burst to life growing the green leaves they need in order to survive. Learn WHY in this funny and educational classroom video appropriate for kindergarten grade school and all ages.

Plants need water carbon dioxide and sunlight to produce their food called glucose. Start by heading outside and collecting leaves. Soon the tree does not have enough sun and water to make both its food and Chlorophyll so it stops making Chlorophyll and the leaves return to its natural color.
As the Sun becomes less intense in fall chlorophyll production slows down. As we know Chlorophyll gives leaves their green colour and is so dominant it hides the other colours in the leaves. You want to gather 4 to 6 leaves of each type.
