Autumn is by far one of my favorite times of the year. There is something refreshing about fall from the crisp air to the magical colors that fill the horizons. This week as the leaves in our front yard began to change color the kids became filled with questions. This science experiment to discover Why Leaves Change Color was the perfect solution for their curious minds.

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.

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.

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 science experiment

To try this leaf science experiment, you will need a few simple materials you probably already have laying around the house. You will need the following supplies:

  • Masson Jars – (Glass Jars)
  • Coffee Filters – we’ve done this a couple times and the BIG ones let kids see more of the chromatography (colors in the leaves)
  • Leaves
  • Rubbing Alcohol
  • Notebook and Pencil to Record Observations

Why 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.

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.

After 12 hours ours hadn’t fully absorbed the liquid but you could begin to see the effect.

What causes leaves to change color

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 such a fun, simple leaf science project your kids will want to try again and again! Each time it is a little different as the coloration in the leaves, amount of rubbin alcohol, etc. affect the colors you will see in the chromatography. Again, we got the most dramatic show of what colors are in a leaf when we used LARGE corree filters that were almost as tall out of the solution as the mason jars were tall.

As the liquid travels up the coffee filter it separates all the colors that were inside the leaf.
