  • What about the Sun?
  • Oh I know, it was our gnome with the paintbrush…

How do Leaves Change Color in the Fall Science Project

To delve into why leaves change color kids need to first understand the purpose of leaves.

While on your nature hunt to collect the leaves for this science project is the perfect opportunity to discuss what jobs leaves are responsible for.  (Don’t miss this leaf scavenger hunt to teach kids about types of trees]

Plants are responsible for creating the oxygen that we breathe. They do this by absorbing water from the ground and carbon dioxide from the air. Using sunlight (through photosynthesis) they turn water and carbon dioxide into oxygen and glucose. Oxygen is what we need to breathe and glucose is what the plant uses to grow. The term photosynthesis means “putting together with light”. The chemical that plants use to make photosynthesis is chlorophyll. Chlorophyll is the same chemical that gives plants their green color.

Why do leaves change color

To find the answer to why leaves change color in the fall, children will need to collect a couple handfuls of leaves. We like to take a fun nature walk, enjoying nature, and collecting fall treasures along the way. Try to collect a variety of fall colored leaves.

Now, sort the fall leaves into containers by color. The sorted cover leaves should then be ground up or torn into pieces and covered with simple rubbing alcohol. Continue mashing as needed, the rubbing alcohol should start showing all the colors in the leaves.

Leaves changing color experiment

Make a cone shape with the coffee filters and place the pointed tip into the leaf and rubbing alcohol mixture and allow it to sit long enough to absorb the liquid.

You will immediately be able to see the coffee filters absorb the liquid.

HINT:  How long it takes to completely absorb the color will depend on how many leaves and how much rubbing alcohol was used.

Why do Leaves Change Color in the Fall Answers

During winter, the days get shorted affecting the amount of sun the leaves are exposed to. Due to this lack of sunlight, plants go into a resting state and live off of the glucose that they stored over the summer. As they shut down for the winter, the green chlorophyll disappears from the leaves. As the bright green fades away, we begin to see yellow and orange colors. Small amounts of these colors have been in the leaves all along.  For example in Maple trees the bright red that shows up is a result of excess glucose being trapped in the leaves.

This is an experiment that is pretty fascinating no matter your child’s age.
